Lymph is the fluid that circulates throughout the lymphatic system.
It is formed when the interstitial fluid is collected through lymph capillaries.
It is then transported through larger lymphatic vessels to lymph nodes, where it is cleaned by lymphocytes before emptying ultimately into the right or left subclavian vein, where it mixes back with the blood.
An important function of lymph is that it captures the bacteria and bring them to lymph nodes, where they are destroyed.
It also helps in the absorption of fatty acids and transport of fat and chyle to the circulatory system.
It helps in the production of immune cells- lymphocytes, monocytes antibody-producing cells (plasma cells).
