Question

Quizplus · Accepted Answer

Lymph capillaries do not have smooth muscle in their walls, but they do have overlapping endothelial cells that act like minivalves to allow the entry of interstitial fluid into the capillary. The other choices, milking action of active muscle fibers, thorax pressure changes during breathing, and lymph capillary minivalve action, are all involved in lymph transport.
