Water crosses capillary beds from high to low hydrostatic pressure by:

Question

Quizplus · Accepted Answer

Water moves from an area of high hydrostatic pressure to an area of low hydrostatic pressure through filtration. This is the primary method by which fluids and nutrients are exchanged between the blood and interstitial fluid in capillary beds. Transcytosis involves the movement of particles across a cell by endocytosis on one side and exocytosis on the other side. Facilitated diffusion relies on carrier proteins to assist in the movement of molecules across a membrane. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration. None of these mechanisms describe the movement of water across capillary beds as well as filtration does.
