The lymphatic system has three functions: 1  The removal of excess fluids from body tissues. 2  This process is crucial because water, proteins, and other substances are continuously leaking out of tiny blood capillaries into the surrounding body tissues. Absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system. 2  Production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells).
The lymphatic system, also recognized as body drainage system, consists of capillaries, vessels, and nodes. Its function is to collect the lymph (rich in proteins and waste products) from the extracellular space within majority of the organs and put into the systemic circulation.or precise mapping of the drainage of solid tumors via lymph nodes, particularly the sentinel lymph node (SLN, the initial lymph node or cluster of nodes approached by metastasized cancer cells originated from solid tumor), a noteworthy curiosity has been observed in the development of imaging approaches.
