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 includes a system of lymphatic capillaries, vessels, nodes, and ducts that collects and transports lymph, which is a clear to slightly yellowish fluid, similar to the plasma in blood.The lymphatic system is important for maintaining your bodyâs fluid balance, and it helps transport some fats.t also works along with the rest of the immune system (namely, the leukocytes) to fight infections.
