Question

Quizplus · Accepted Answer

This description best fits lymph capillaries, which are structures composed of endothelial cells with flap-like minivalves that are opened as fluid accumulates in peripheral tissue. Blood capillaries, on the other hand, lack these valves and rely on pressure gradients for transport. Lymph nodes, cisterna chyli, and the thoracic duct are all parts of the lymphatic system but do not fit the given description.
