Filtration

Definition

noun, plural: filtrations

(1) The movement of water and solutes across the cell membrane due to hydrostatic pressure from the cardiovascular system.

(2) The process of separating suspended particles from the fluid through a porous material in which the fluid can pass while the suspended particles are retained.


Supplement

An example of filtration in the body is renal (ultra)filtration, a process in which the blood is filtered in the glomerulus of the kidney so that substances (e.g. cells and proteins) that are essential can be retained and selectively reabsorbed by the body.
