transport

 [trans´port]
1. movement of materials in biologic systems, particularly across the cell membrane into and out of cells or across epithelial layers.
2. in the nursing interventions classification, a nursing intervention defined as moving a patient from one location to another.
active transport see active transport.
oxygen transport the carrying of oxygen through the bloodstream bound to hemoglobin (see oxyhemoglobin).
passive transport the movement of materials, usually across cell membranes, by processes not requiring expenditure of metabolic energy. See also active transport.

trans·port

(trans'pōrt),
The movement or transference of biochemical substances in biologic systems.
[L. transporto, to carry over, fr. trans- + porto, to carry]

transport

/trans·port/ (trans´port) movement of materials in biological systems, particularly into and out of cells and across epithelial layers.
active transport  movement of materials in biological systems resulting directly from expenditure of metabolic energy.

(A) Passive transport exemplified by diffusion of potassium ions across the plasma membrane, through specific ion channels, down a concentration gradient; (B) active transport exemplified by the cellular sodium pump, which uses ATP hydrolysis to create gradients of sodium and potassium across the plasma membrane.
bulk transport  the uptake by or extrusion from a cell of fluid or particles, accomplished by invagination and vacuole formation (uptake) or by evagination (extrusion); it includes endocytosis, phagocytosis, pinocytosis, and exocytosis.

transport

[trans′pôrt]
Etymology: L, trans, across, portare, carry
the movement or transference of biochemical substances from one site to another. Active transport involves an expenditure of energy, whereas passive transport allows movement down a gradient without an energy expenditure.

trans·port

(trans'pōrt)
1. The movement or transference of biochemical substances in biologic systems.
2. In physical therapy, movement of patients from one area (or surface) to another.

transport,

n the movement of biochemical substances from one site to another.
transport, active,
n transport of substances through membranes or epithelium, requiring metabolic energy.
transport, passive,
n transport along a gradient without the use of metabolic energy.
