- The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste, and other unwanted materials.
- It consists of lymphatic vessels, lymph nodes, the spleen, thymus, and tonsils.
- Lymphatic vessels are similar to blood vessels but carry a clear fluid called lymph instead of blood.
- Lymph nodes are small, bean-shaped structures that filter lymph and contain immune cells that help fight infections.
- The spleen is the largest lymphatic organ and filters blood, removing old or damaged red blood cells and storing platelets.
- The thymus is located in the chest and plays a crucial role in the development and maturation of T-cells, which are important for immune response.
- Tonsils are small masses of lymphoid tissue located in the back of the throat that help trap and filter bacteria and other pathogens.
- The lymphatic system works in close coordination with the circulatory system to maintain fluid balance and defend against infections.
- Lymph is formed from interstitial fluid that is collected by lymphatic vessels and transported back into the bloodstream.
- Lymph nodes play a vital role in the immune response by filtering lymph and activating immune cells to fight off infections.
- Lymphatic vessels also play a role in the absorption of fats from the digestive system, transporting them to the bloodstream.
- The lymphatic system can be affected by various diseases and conditions, including lymphedema (swelling due to impaired lymphatic drainage), lymphoma (cancer of the lymph nodes), and infections such as lymphangitis or cellulitis.
