What is the term for fluid absorbed by lymph capillaries from between cells?

The term for fluid absorbed by lymph capillaries from between cells is lymph. Lymph is the clear fluid that circulates within the lymphatic system, which plays a crucial role in maintaining fluid balance in the body and is integral to the immune system. When interstitial fluid—the fluid found in the spaces between cells—enters the lymphatic vessels, it is referred to as lymph. This fluid is important as it contains a mixture of proteins, waste products, and immune cells.

In contrast, plasma refers specifically to the liquid component of blood, which transports blood cells, nutrients, hormones, and waste products throughout the body. Serum is the part of blood that remains after clotting has taken place and does not contain clotting factors. Interstitial fluid is the fluid that exists in the spaces between cells, and while it is the source of lymph, it is not the same as lymph itself, which is the processed form of that fluid once it's collected by the lymphatic system. Thus, referring to the fluid that is absorbed by lymph capillaries specifically as lymph is accurate and reflects its unique role within the lymphatic system.
