Question

multiple choice question
which term describes the physical force exerted by a liquid against a surface such as a capillary wall?

hydrostatic pressure
oncotic pressure
orthostatic pressure
hypostatic pressure

Explanation:

Hydrostatic pressure is the pressure exerted by a fluid (liquid) at equilibrium due to the force of gravity, and it acts against surfaces like capillary walls. Oncotic pressure relates to colloidal osmotic pressure, orthostatic pressure is about blood pressure changes with posture, and hypostatic pressure is not a standard term for this context.

Answer:

A. Hydrostatic pressure
