Question

Quizplus · Accepted Answer

If a valve is damaged, permitting backflow, a section of the vein is subjected to the pressure exerted by a larger volume of blood under the influence of gravity. The vein swells as it becomes engorged and surrounding tissue becomes edematous because increased hydrostatic pressure pushes plasma through the stretched vessel wall.
