valve
(valv) [L. valva, leaf of a folding door]Any of various membranous structures in a hollow organ or passage that temporarily close to permit the flow of fluid in one direction only.
aortic valve
Abbreviation: AoVThe valve at the junction of the left ventricle and the ascending aorta. It is composed of three segments (semilunar cusps) and prevents regurgitation. See: cardiac valve for illus.
Bauhin valve

Mitral valve.Bjork-Shiley heart valve
A synthetic artificial heart valve that is no longer commercially available but remains implanted in thousands of patients. The valve has been known to fracture at its struts during use, which results in death in the majority of cases.
cardiac valve
Any of the four valves that prevent the backflow of blood as it passes into, through, and out of the heart. In order of the entry of the venous blood into the right atrium, they are the tricuspid, pulmonary, mitral, and aortic. See: illustration
Carpentier-Edwards valve
See: Carpentier-Edwards valve.check valve
A valve that permits fluids or gases to flow in just one direction. Check valves are used in infusion sets to prohibit backflow of fluids during intravenous therapy.
coronary valve
The coronary sinus valve at the entrance of the coronary sinus into the right atrium. Synonym: thebesian valve
eustachian valve
The valve at the entrance of the inferior vena cava.
external nasal valve
The outermost opening of the nose (the alar rim).
flutter valve
A one-way valve used in chest tube drainage systems that allows fluids or gases to flow out of the chest, but does not let them reenter the body
Synonym: Heimlich flutter valve; Heimlich valveGerlach valve
See: Gerlach valvehigh-pressure relief valve
A safety device built into a ventilator circuit that protects the patient from excessively high airway pressures by venting excess pressure into the atmosphere.
Houston valve

Lacrimal plica.ileocecal valve
A projection of two membranous folds of the ileum of the small intestine into the cecum of the colon. It prevents backup of fecal material into the small intestine.
Synonym: valvula coliinspiratory impedance threshold valve

Nasal valve.Krause valve
See: Krause, Karlleft atrioventricular valve
Mitral valve.mitral valve
The valve that closes the orifice between the left cardiac atrium and the left ventricle during ventricular systole.
Synonym: bicuspid valve; left atrioventricular valvenasal valve
The site of greatest obstruction to airflow through the nasal passages. It extends from the bony cave near the piriform aperture into part of the cartilaginous vestibule of the nose. Synonym: internal nasal valve
pop-off valve
A safety valve that releases gas into the atmosphere from a ventilator circuit when the pressure in the circuit exceeds a known, safe level.
prosthetic heart valve
A substitute valve used to replace a diseased valve. There are two main types of prostheses: those made from biological tissues, e.g., the heart valves of animals, esp. pigs, and those made from biocompatible materials, e.g., metals or polymers. Biocompatible mechanical valves may be constructed in a variety of ways, e.g., from a ball that moves up and down in a cage; with bileaflet valves that close in the midline; or with a single leaflet (which tilts to open and close). See: illustration
pulmonary valve
The valve at the junction of the right ventricle and pulmonary artery. It is composed of three semilunar cusps and prevents regurgitation of blood from the pulmonary artery back into the right ventricle. See: cardiac valve for illus.
pyloric valve
The prominent circular membranous fold at the pyloric orifice of the stomach. Synonym: valvula pylori
reducing valve
A device to reduce the pressure of gas that has been compressed in a cylinder.
right atrioventricular valve
Tricuspid valve.semilunar valve
The type of valve separating the heart and aorta and the heart and pulmonary artery. See: cardiac valve for illus.
thebesian valve
Coronary valve.tricuspid valve
Abbreviation: TVThe valve that closes the orifice between the right cardiac atrium and right ventricle during ventricular systole. Synonym: right atrioventricular valve; valvula tricuspidalis See: cardiac valve for illus.
valve of Varolius
Ileocecal valve.tricuspid valve
Abbreviation: TVThe valve that closes the orifice between the right cardiac atrium and right ventricle during ventricular systole. Synonym: right atrioventricular valve; valvula tricuspidalis See: cardiac valve for illus.

Patient discussion about TV
Q. Is it possible to get addicted to T.V? My mother says I shouldn’t watch more than an hour and a half a day or I’ll get addicted. Could be? And what that means anyway? Is it harmful?
A. ? well, I think you misunderstood your mother’s intention. It’s not that if you watch an hour and 28 minutes a day you are safe from T.V. addiction, it’s not like drugs that you can measure it and say that a few grams can get you addicted for life. But it is bad for your plans of becoming anything in this life.
