Functions
Absorption: One main function of the lymphatic system is to absorb fats and fat-soluble vitamins from the digestive system. It then delivers these nutrients to different cells to be used.
Removal: The lymphatic system removes excess fluid and waste product from the interstitial spaces between cells. It also aids the immune system by destraying debris, dead blood cells, pathogens, toxins, and cancer cells.
Production: Finally the lymphatic system produces immune cells such as lymphocytes, monocytes, and antibody producing cells called plasma cells

Thymus
The thymus is a large gland that covers the top of the heart in children. Lymphocytes travel to the thymus in order to get bone marrow and then divide and turn into T-lymphocytes. These then migrate to other organs and divide further. The thymus degenerts after puberty because its main goal is to help set up the immune system.
Lymph Node
Lymph nodes are present at different locations in the body. Its main function is to carry out the filtration of lymph as well as to produce lymphocytes, antitoxins, and antibodies.
Spleen
The spleen is a secondary lymphoid organ taht is normally purple/red in color but turns pink when fighting infections. Spleen filters blood rather than lymph. One of its main functions is to bring blood in contact with lymphocytes.
Composition of lymph
Lymph has a composition that is very similar to plasma and has the same composition as interstitial fluid. It contains cells such as white blood cells and it is a watery clear liquid. As it passes through lymphnodes it comes in contact with blood and accumulates proteins and lymphocytes. The composition of lymph depends on the tissue it is draining.
