What Best Describes Hydrostatic Pressure

Question

What best describes hydrostatic pressure?
A)Hydrostatic pressure is the force that fluids exert against the capillary wall.
B)Hydrostatic pressure is created by the number of solute particles present in solution.
C)Hydrostatic pressure is created by the number of proteins present in solution.
D)Hydrostatic pressure is the force that proteins exert in solution.

Accepted Answer

Hydrostatic pressure is the force exerted by fluids against the capillary wall. It is mainly determined by the volume of fluid in the vessel and the force of gravity. This pressure is balanced by the oncotic pressure, which is the force exerted by proteins in the blood vessels. Together, they help regulate the movement of fluids and solutes across the capillary wall.
