Lymph is a colorless fluid that contains white blood cells that soak tissues and flow through the lymphatic system into the bloodstream.
An important function of the lymph is that it captures bacteria and carries them to the lymph nodes, where they are destroyed.
It also helps to absorb fatty acids and transport fats and fats to the circulatory system.
The lymphatic system, a complex network of vessels, is essentially a drainage system inside the body, carrying excess fluid and metabolic waste from the interstitium to the circulatory system.
