Detailed explanation-1: -As the interstitial fluid begins to accumulate, it is picked up and removed by tiny lymphatic vessels and returned to the blood. As soon as the interstitial fluid enters the lymph capillaries, it is called lymph. Returning the fluid to the blood prevents edema and helps to maintain normal blood volume and pressure.
Detailed explanation-2: -Only 10% of interstitial fluid is reabsorbed by the cell. The rest of 90% of interstitial fluid that is not reabsorbed is collected by the lymph vessel at the venous end of the capillary bed.
Detailed explanation-3: -This is important because water, proteins, and other substances are always leaking out of tiny blood capillaries into the body tissues around them. If the lymphatic system didn’t drain it, this extra fluid would build up in the tissues and make them swell.
