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.

(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.

Etymology: L, trans, across, portare, carry
