The movement of fluid across the arterial end of capillary membranes into the interstitial fluid surrounding the capillary is an example of which fluid movement process?
A)Hydrostatic pressure
B)Osmosis
C)Diffusion
D)Active transport

Question

Quizplus · Accepted Answer

Hydrostatic pressure is the mechanical force of water pushing against cellular membranes. Osmosis is the movement of water "down" a concentration gradient, that is, across a semipermeable membrane from a region of higher water concentration to a region of lower water concentration. Diffusion is the movement of a solute molecule from an area of greater solute concentration to an area of lesser solute concentration. Active transport requires a life, biologic activity, and the expenditure of metabolic energy.
