Verified step by step guidance

Understand that lymph is a fluid that is part of the lymphatic system, which plays a crucial role in immune function and fluid balance.

Recognize that interstitial fluid is the fluid that surrounds the cells in tissues, providing them with nutrients and a means to remove waste.

Learn that lymph originates from the interstitial fluid. As blood circulates through the body, some plasma leaks out of the capillaries into the surrounding tissues, becoming interstitial fluid.

Realize that this interstitial fluid is collected by the lymphatic vessels, where it is then called lymph. This process helps maintain fluid balance in the body by returning excess fluid to the bloodstream.

Note that lymph does not originate directly from the bloodstream, cerebrospinal fluid, or the digestive tract, although it can carry substances absorbed from the digestive tract, such as fats, into the bloodstream.
