lymphatic system

Also known as lymphoid systems, lymphatic vascular system

a part of the defense system (immune system) of vertebrate animals against pathogens

AI overview

The lymphatic system is a network of vessels and tissues that works as part of your body's defense against harmful pathogens like bacteria and viruses. It helps protect you by filtering and moving fluid through your body to identify and fight off infections.

Article

The lymphatic system, or lymphoid system, is an organ system in vertebrates that is part of the immune system and complementary to the circulatory system. It consists of a large network of lymphatic vessels, lymph nodes, lymphoid organs, lymphatic tissue and lymph. The Latin word for lymph, lympha, refers to the deity of fresh water, "Lympha".

Unlike the circulatory system, which is a closed system, the lymphatic system is open. Lymph originates in the interstitial fluid that leaks from blood in the circulatory system into the tissues of the body. This fluid carries nutrients to the cells and collects waste products, bacteria, and damaged cells, before draining into the lymphatic vessels as lymph. The circulatory system processes an average of 20 litres (5.3 US gal) of blood per day through capillary filtration, which removes plasma from the blood. Roughly 17 litres (4.5 US gal) of the filtered blood is reabsorbed directly into the blood vessels, while the remaining 3 litres (0.79 US gal) are left in the interstitial fluid. The lymphatic system provides an accessory return route to the blood for this remainder.
