Which of the following is an example of water shifting due to hydrostatic pressure?

Question

Quizplus · Accepted Answer

Hydrostatic pressure is the pressure exerted by a fluid at rest. When someone stands for a long period of time, gravity causes the hydrostatic pressure in the blood vessels of the feet and ankles to increase, resulting in water shifting out of the blood vessels and into the surrounding tissues, causing swelling. This is an example of water shifting due to hydrostatic pressure. Option A refers to loss of plasma volume due to sweating, which is an example of fluid loss due to sweating. Option C refers to swelling of cells due to high intracellular sodium concentrations, which is an example of osmotic pressure. Option D refers to passive movement of water molecules from areas of high solute concentration to areas of low solute concentration, which is an example of osmosis.
