Answer 1

The correct option is D Return interstitial fluid to blood.

D. Return interstitial fluid to blood

EXPLANATION: After the accumulation of interstitial fluid, it is picked up and removed by small lymphatic vessels and returned to the blood. When the interstitial fluid enters the lymph capillaries, it is called lymph. Lymph helps to return interstitial fluid to blood and prevents edema. It also helps to maintain the blood pressure and blood volume.
