Question

Quizplus · Accepted Answer

Standing still for 8 hours can cause blood to pool in the lower legs due to the force of gravity. This can lead to an increase in hydrostatic pressure in the capillaries, which can cause fluid to leak out into the surrounding tissues, resulting in swelling (edema). Additionally, the low blood pressure that Tina experienced may be due to decreased venous return from her legs, which could further contribute to the fluid accumulation and swelling.
