Fluid Balance: The lymphatic system collects excess interstitial fluid (the fluid that surrounds cells) and returns it to the bloodstream. This process helps maintain normal fluid levels in the body and prevents swelling (edema).
Immune Defense: As a vital part of the immune system, the lymphatic system produces and transports lymphocytes (a type of white blood cell) that help defend the body against infections and diseases. Lymph nodes filter lymph fluid, trapping pathogens and initiating immune responses.
Fat Absorption: The lymphatic system plays a key role in the absorption of fats and fat-soluble vitamins from the digestive tract. Specialized lymphatic vessels called lacteals in the intestines absorb these nutrients and transport them back to the bloodstream in a milky fluid known as chyle.
Waste Removal: The lymphatic system helps remove waste products, toxins, and abnormal cells from the lymph fluid, filtering them out through lymph nodes before returning the cleaned fluid to the circulatory system.
Transport of Immune Cells: The lymphatic system serves as a transport network for immune cells, allowing them to move throughout the body to sites of infection or inflammation, enhancing the body’s ability to respond to threats.
