Description

Technical Field

[0002] Lymphatic return refers to the process in which part of the body's tissue fluid enters the capillary lymphatic vessels to form lymph, then gathers along the lymphatic vessels and finally returns to the blood through the right lymphatic duct and thoracic duct. The generation and return of lymph are of great significance in: recycling protein in tissue fluid, transporting fat and other nutrients, regulating the fluid balance between plasma and tissue fluid, and removing red blood cells and other foreign matter from tissues. Under normal circumstances, the lymph in the lymphatic vessels flows slowly and continuously toward the centripetal. The flow rate is equivalent to about 1 / 10 of venous blood. In a normal person at rest, about 120 ml of lymph returns to the veins every hour.
