Question

1 which of the following happens when a person stands in one place for a long period of time? multiple choice gravity causes an increased accumulation of blood in the veins in the feet and legs. blood pressure rises in the venules of the feet. edema may occur in the lower extremities. all of the choices are correct. without muscular movement, the pressure at the venous end of the capillaries increases.

Explanation:

When a person stands still for a long time:

• Gravity causes blood to pool in the lower - limb veins (due to lack of muscular pumping action which normally helps return blood to the heart).
• This pooling leads to increased blood pressure in the venules (small veins) of the feet as blood accumulates.
• The increased pressure at the venous end of capillaries (from blood stasis) can cause fluid to leak out into the interstitial space, resulting in edema (swelling) in the lower extremities.

Answer:

D. All of the choices are correct.
