Question

Excess interstitial fluid is collected and returned to the blood by the
A)lymphoid system.
B)lymph nodes.
C)venules.
D)capillaries.

Accepted Answer

Excess interstitial fluid is collected and returned to the blood by the lymphoid system, which includes lymphatic vessels, lymph nodes, and lymphatic organs such as the spleen and thymus. The lymphatic vessels collect interstitial fluid, which is then transported to the lymph nodes where it is filtered and any harmful substances are removed. The lymphatic fluid, now called lymph, is then returned to the bloodstream via the thoracic duct.
