Pulmonary lymphatic function and its research progress in pulmonary diseases

The lymphatic system is a unidirectional network in which lymph fluid flows centripetally along a series of lymphatic channels and eventually into the veins, so the lymphatic system can also be considered an auxiliary part of the venous system and an important part of the cardiovascular system. The lymphatic system, which regulates interstitial fluid balance, lipid absorption, and immune monitoring, and its imbalance can lead to a variety of diseases. The pulmonary lymphatic system plays a very important role in many lung diseases, involving maintaining fluid balance, antigen presentation, etc., in addition, it will affect the survival of the transplant after lung transplantation.
