Chapter 18, Problem 16CYR
Summary Introduction
Introduction:
Capillaries usually form branching networks called capillary beds, which allow quick exchange of substances between cells and the blood. There are two main types of pressure in the capillaries: the colloidal osmotic pressure (COP) and the hydrostatic pressure (HP). These cause water to move inopposite directions. The net filtration pressure (NFP) is the overall pressure that can drive water in and out of the capillaries. It is equal to the difference between the opposite HP (drives water out) and the COP (drives water in).
