system

[sis′təm]

Etymology: Gk, systema

1 a collection or assemblage of parts that, unified, make a whole. Physiologic systems, such as the cardiovascular or reproductive system, are made up of structures specifically able to engage in processes that are essential for a vital function in the body.

2 a set of computer programs and hardware that work together for some specific purpose.

---

system,

n a set or series of organs or parts that unite in a common function.

system, acid-base buffer,

n the system by which a virtually constant pH level of the blood and body fluids is maintained. The base and acid electrolytes associated with normal metabolism are continuously introduced into the bloodstream. Notwithstanding the marked amounts of base or acid or both introduced into the bloodstream during exercise, rest, hunger, or the ingestion of fluid and solid foods, the pH level of the blood remains rather constant between 7.3 and 7.5. Four means by which this relatively narrow but constant pH level is maintained are: the buffer system of the blood, tissue and cell fluids, and mineral salts of the bone matrix; excretion and retention of carbon dioxide by the lungs; excretion of an acid or alkaline urine; and the formation or excretion of ammonia and organic compounds.

system, apothecaries'

n a nondecimal system of weights and measures traditionally used by druggists. See also system, avoirdupois.

system, autonomic nervous,

n See autonomic nervous system (ANS).

system, avoirdupois

n a commercial nondecimal system of weights and measures. See also system, apothecaries'.

system, central nervous (CNS),

n the brain and spinal cord, including their nerves and end organs; controls all voluntary acts.

system, circulatory,

n the heart and blood vessels. Three major groups of blood vessels are defined: arteries, capillaries, and veins. The system transports metabolites to and from the tissue cells.

system, computer,

n an assembly of procedures, processes, methods, routines, techniques, and equipment united by some form of regulated interaction to form an organized whole. It is an approach to a complex problem.

system, flowchart,

n a pictorial diagram illustrating the flow of information into, through, and out of a system of programs.

system, hematopoietic

n a term used to describe collectively the blood, bone marrow, lymph nodes, spleen, and reticuloendothelial cells.

system, masticatory,

n the organs and structures primarily functioning in mastication: the jaws, teeth, and their supporting structures; temporomandibular articulation; mandibular musculature; tongue; lips; cheeks; and oral mucosa and their nerve supplies.

system, metric,

n a decimal system of weights and measures almost universally used in scientific and professional work, including the writing of prescriptions. The individual units are based on an international set of standards, notably the meter, liter, and kilogram. In dentistry, measurement is done by the metric system.

system, musculoskeletal,

n the system of body structures that provides the energy and movement necessary for the functions of life. The muscles, bones, and connective tissues of the body are grouped together into one system, and they are intimately connected in their individual and combined functions. E.g., for muscle to accomplish its ultimate purpose of movement by contraction, bone, leverage, and connective tissue are required to transmit the force that the contraction generates. In the oral cavity and its related structures the musculoskeletal tissues fulfill the mechanical and structural requirements for movement of the mandible and some related visceral functions, such as respiration and digestion.

system, neurohormonal,

n the system by which the hormone secretions of the endocrine glands function in part as the regulators of both visceral and somatic function and have intimate anatomic and functional relationships with the nervous system by the union of the pituitary gland and the hypothalamus of the cerebrum. The pituitary gland has a pars nervosa, which is an extension of the anterior part of the hypothalamus, and a pars intermedia, which is an epithelial evagination of the secretory tissue from the stomodeum of the embryo. From its position in the cranial structures in the sella turcica, the pituitary gland regulates, by its union with the nervous system, the whole endocrine system, with its many glands; these glands in turn partially regulate the viscera and somatic muscle organs.

system, occlusal (occlusal scheme),

n the form or design and arrangement of the occlusal and incisal units of a dentition or of the teeth on a denture. See also system, masticatory.

system, parasympathetic nervous,

n one of the motor divisions of the autonomic nervous system. It is described as the
craniosacral division and does not have the simplified structural apparatus of the strong sympathetic adrenal axis about which to function. It inhibits the heart, contracts the pupils, and, in emotional states, produces a vagus-insulin axis of activity. The several parts function rather independently. The ocular division relates to the midbrain, and the bulbar division relates to the hindbrain. The bulbar division supplies the facial, glossopharyngeal, and vagus nerves. It also supplies the secretory and vasodilator fibers of the salivary glands and mucous membranes of the oral cavity and pharynx. In conditions of very loud noise or unusual anxiety states, the parasympathetic system causes unaccounted-for spontaneous urination, excessive salivary and gastric juices, and either nausea or vomiting.

system, proaccelerin-accelerin,

n See factor V.

system, proconvertin-convertin,

n See factor VII.

system, stomatognathic,

n the combination of all the structures involved in speech and the reception, mastication, and deglutition of food. The system is composed of the teeth, jaws, muscles of mastication, epithelium, and temporomandibular joints and nerves that control these structures.

system, sympathetic nervous,

n one of the two opposing motor systems in the autonomic nervous system that mediate the activity of the viscera. (The other is the
parasympathetic system.) It is composed of 21 or 22 ganglia in chains on each side of the spinal cord. The fibers connect with the spinal cord through these ganglia. The actions are closely allied to the action of the medulla of the adrenal gland; thus a sympathetic-adrenal axis that functions as a unit to protect and regulate the body environment may be conceived. The sympathetic control is modified by the volitional somatic control of the patient. The volitional control, superimposed on the autonomic control, gives rise to great variations in motor patterns, as seen in the face in the presence of emotional changes, such as in the blushing of shame and pallor of fear.

system, vascular, closed tube,

n the type of vascular system, as in humans, in which the blood circulates through the vessels (or tubes) and is not dissipated into the tissues. The closed vascular tube system offers resistance to the pumping action of the heart because the pressures are cumulative with each pumping action. The elastic walls in the arterial vessels, particularly in the aorta, absorb the additional energy and release it slowly, thus creating the possibility of maintaining a fairly steady and safe pressure head throughout the vascular system. The high-pressure point at the height of cardiac contraction is the
systole, and the low point before the ventricular contraction is the
diastole.

system, vascular, open tube,

n in some vertebrates a vascular system with an open end that causes the blood fluid to dissipate into the tissues. This system starts with a maximal head pressure that diminishes until inertia in the blood is overcome. The blood is returned to the heart by muscle function, gravity, and diffusion. The blood pressure in this system fluctuates from a maximum at the heart to a minimum at the tissue cell.

system, venous,

n a system of interconnected blood vessels that returns blood to the heart from the tissue and capillary bed through progressively larger vessels. The following affect the return of blood to the heart: thoracic pressure, associated with respiration; gravity, associated with body posture; the valves, diameter of the lumen, and muscle structure of the veins; muscle contraction of the somatic structures; the pressures in the arteriole system and capillary bed; and the nervous and hormonal system controls that regulate cardiomuscular activity. The influences over the venous system circulation are collectively termed
venopressor mechanisms.

system

1. a set or series of interconnected or interdependent parts or entities (objects, organs or organisms) that act together in a common purpose or produce results impossible by action of one alone.

2. an organized set of principles or ideas.

The parts of a system can be referred to as its elements or components; the environment of the system is defined as all of the factors that affect the system and are affected by it. A living system is capable of taking in matter, energy and information from its environment (input), processing them in some way, and returning matter, energy and information to its environment as output.

An open system is one in which there is an exchange of matter, energy and information with the environment; in a closed system there is no such exchange. A living system cannot survive without this exchange, but in order to survive it must maintain pattern and organization in the midst of constant change. Control of self-regulation of an open system is achieved by dynamic interactions among its elements or components. The result of self-regulation is referred to as the steady state; that is, a state of equilibrium. homeostasis is an assemblage of organic regulations that act to maintain steady states of a living organism.

Definitions of individual systems are to be found under those titles, e.g. alimentary system.

general s's theory

a theory of organization proposed by Ludwig von Bertalanffy in the 1950s as a means by which various disciplines could communicate with one another and duplication of efforts among scientists could be avoided. The theory sought universally applicable principles and laws that would hold true regardless of the kind of system under study, the nature of its components, or the interrelationships among its components. Since the introduction of the general systems theory, theoretical models, principles and laws have been developed that are of great value to scientists in all fields, including those of medicine, nursing, other health-related professions, and in veterinary medicine.

heterogeneous system

a system or structure made up of mechanically separable parts, as an emulsion or suspension.

homogeneous system

a system or structure made up of parts that cannot be mechanically separated, such as a solution.

system

1. A group of body organs serving a common function (e.g. the nervous system).

2. A combination of parts or things forming a unitary whole (e.g. optical system).

3. A method of arrangement or classification.
autonomic nervous system  (ANS) A part of the nervous system involved in the regulation of the internal environment (homeostasis) which is achieved mostly by controlling cardiovascular, digestive, respiratory and reproductive functions of the body, as well as salivation, perspiration, pupil size, urinary and genital systems. Most of these activities are involuntary, although, for example, breathing can be partly voluntary. Sensory information from the visceral sensory neurons (afferent) located in the peripheral nervous system (PNS), such as monitoring the composition of the blood and stomach, is conveyed to the central nervous system (CNS), especially the hypothalamus and medulla oblongata, where it is integrated. Motor neurons (efferent) of the ANS consist of a set of two neurons: the first with its cell body in the CNS project to an autonomic ganglion (preganglionic neuron) and a second motor neuron (postganglionic neuron) outside the CNS, innervates visceral effectors (target organs). The efferent part of the ANS has two principal divisions: sympathetic and parasympathetic. Many organs receive autonomic fibres from both divisions. The preganglionic sympathetic neurons have their cell bodies in the lateral horn and the first two or three lumbar segments of the spinal cord, while the parasympathetic preganglionic neurons are found in the brainstem and their axons leave the brain via the third, seventh, ninth and tenth cranial nerves. Sympathetic postganglionic neurons project to sympathetic ganglia from which axons project to the eyes, lacrimal glands, salivary glands, respiratory, cardiovascular, digestive, urinary and reproductive systems. Parasympathetic postganglionic neurons are located in or near the target organs. They also innervate the eyes, lacrimal glands, salivary glands, respiratory, cardiovascular, digestive systems, urinary and reproductive systems. Examples: sympathetic stimulation causes pupil dilatation and relaxation of the ciliary muscle, while parasympathetic stimulation causes pupil constriction, accommodation and lacrimal secretion.The
sympathetic nervous system  dominates in stressful situations causing a 'fight or flight' response, while the parasympathetic nervous system primarily regulates those activities that conserve and restore energy. Acetylcholine is the neurotransmitter for sympathetic and parasympathetic preganglionic neurons and for postganglionic parasympathetic neurons, which act on muscarinic receptors, while noradrenaline (norepinephrine) is the neurotransmitter for all postganglionic sympathetic neurons (except for the sweat glands) which act on adrenergic receptors. See acetylcholine; adrenergic receptors.
boxing system A method of measurement of the eyesize of spectacle frames. It is based on a rectangle with its horizontal and vertical length tangential to the edges of the lens. The horizontal lens size is equal to the horizontal length of the rectangle. Syn. box system of lens measurement; boxing method. See boxing centre; standard optical position centre.
catadioptric system An optical system employing both reflecting and refracting components as used, for example, in a lighthouse. This design makes long focal length more compact and mirrors, unlike lenses or prisms, are free of chromatic aberration. See catadioptric image.
central nervous system (CNS) The largest part of the nervous system, comprising the brain and the spinal cord. The brain is encased and protected by the skull and the spinal cord by the vertebrae, as well as the meninges and the blood-brain barrier that protects against blood-borne toxins. The central nervous system processes and integrates sensory information received from the peripheral nervous system and issues appropriate motor responses.
centred optical system See optical system.
compound optical system An optical system consisting of more than one lens (e.g. the eyepiece of a telescope).
immune system A complex system that protects the body against infection, disease and malignant cells by producing the immune response. The system includes skin and mucous secretions, white blood cells (leukocytes), lymphocytes (B cells and T cells), killer T cells, complement system (proteins in the blood) and antibodies. Disorders of the immune system can cause disease: they include immunodeficiencies due to aging, alcoholism, malnutrition, etc., immune responses against its own cells (autoimmunity), or damaging effects caused by the immune system (hypersensitivity). See autoimmune disease; hypersensitivity.
magnocellular visual system That part of the visual pathway from the photoreceptors in the retina to layer 4Cα (and to a lesser extent in layer 6) of the visual cortex and then projected to area V5, which is mainly responsible for transmitting information about movement, depth perception and high contrast targets. Action potentials are transmitted faster in this pathway because of the large diameter axons of these neurons than in the parvocellular pathway. Syn. dorsal stream; parietal pathway; transient visual system; 'where' system. See M cell; dyslexia; lateral geniculate bodies; two visual systems theory.
optical system A collection of lenses, prisms, mirrors, etc. which act together to produce an image of an external object. If the axes of all the components coincide, the system is called a centred optical system.
parvocellular visual system That part of the visual pathway from the photoreceptors in the retina to layer 4Cβ, (and to a lesser extent in layers 4A and 6) of the primary visual cortex and then projected to area V4, which is mainly responsible for transmitting information about visual acuity, form vision, colour vision and low contrast targets. Syn. sustained visual system; ventral stream; 'what' system. See visual association areas; ganglion cell; P cell; lateral geniculate bodies; two visual systems theory.
peripheral nervous system (PNS) The part of the nervous system which consists of the nerves and neurons that are outside the brain and spinal cord. It comprises the cranial nerves, spinal nerves and the autonomic nervous system. The primary role of the peripheral nervous system is to transmit sensory information about the external and internal milieus to the central nervous system and to transmit motor commands to the effectors such as muscles and glands. Note: some authors do not consider the autonomic nervous system as part of the peripheral nervous system. It is, however, a separate entity, which is part central and part peripheral.
'what' system See parvocellular visual system.
'where' system See magnocellular visual system.

Patient discussion about gets out of system.

Q. how long dose pills take to get pills out your system

A. How long it takes to leave your system depends on how much you smoke. But the time maxes out at around 45 days. One smoking session for someone with a clean system takes about 3-4 days to be clean. Smoke 2 days later and then have to wait about a week, and so on. The time it will take roughly doubles every time you smoke until it maxes at about 45 days to be clean. So if you are maxed out and you wait about 2 weeks and then smoke again, you're basically back to 45 days. This also depends on the test. Most job drug tests only test down to about 100 nanograms, which isn't dead accurate but will pick up if you are a smoker obviously. Court-appointed tests can test anywhere down to 10-20 nanograms, which is very accurate, and can also detect high levels of water, and any other drug test liquids. You can not fool those tests, and drinking water and tea does nothing for getting weed out of your system at all. The ONLY way to get it out is time, because it is in your blood. Hope this helps.

Q. Why does the body attack itself in autoimmune diseases? And if it’s possible - How come it doesn’t happen most of the time?

A. Wow, good question…I got Lupus which is an autoimmune disease. And when I checked about it I discovered that apparently you are born with a perfect immune system. There are billions of white cells that can detect any foreign or self antigens. But then they are “educated” in the thymus and all those that recognize self die. But sometimes a cell that recognize similar self antigens stay, and no one knows why, they can just attack one day for no apparent reason. I hope I helped.

Q. It feels like I cannot breath properly, my chest feels heavy and Whenever i eats something it gets even more. If i don't eat much i get gases problem. I am regularly having constipation if i don't take proper medicine. Mostly i have been diagnosed as Digestive System problem, stomach problem, dryness in body and no Problem with my breathing system just cause of gases which causes my chest to remain heavy. I am worried because i never gets my real power in breathing and my digestive system is not getting well. Kindly suggest.

A. I take milk regularly have no problem with it nor with any specific food or i have never tried to look at this aspect. However i do feel stomach problem with foods heavy for stomach like burger or too much oily things..
