The lymphatic system consists of a network of lymph vessels, lymph nodes, lymphoid organs, and lymphatic tissue. Its primary functions include maintaining fluid balance in the body, transporting immune cells, and facilitating the absorption of fats and fat-soluble vitamins from the digestive system. Key components include:
- Lymph - A clear fluid that circulates through the lymphatic system.
- Lymph Vessels - A network of vessels that transport lymph from tissues to the bloodstream.
- Lymph Nodes - Small, bean-shaped structures that filter lymph and house immune cells.
- Spleen - An organ that filters blood, recycles iron, and helps regulate immune responses.
- Thymus - An organ where T-cells mature and develop, playing a crucial role in the immune system.
- Tonsils - Lymphoid tissues located in the throat that help protect against pathogens entering the body through the mouth or nose.
- Bone Marrow - Produces blood cells, including lymphocytes that are essential for immune function.
The lymphatic system is integral to the body’s immune response and fluid homeostasis.
