Answer:
Here are the key functions of the lymphatic system:
Fluid Balance: The lymphatic system collects excess interstitial fluid, which contains water, solutes, and small proteins that have leaked out of blood capillaries, and returns it to the bloodstream. This helps maintain the balance of fluid levels in the body tissues.
Immune Response: The lymphatic system plays a crucial role in the body's immune defense. Lymph nodes, which are small bean-shaped structures along the lymphatic vessels, contain immune cells called lymphocytes that help recognize and fight off pathogens, such as bacteria and viruses. Lymph nodes filter lymph, removing harmful substances and activating immune responses when necessary.
Absorption of Dietary Fats: Specialized lymphatic vessels called lacteals in the small intestine absorb dietary fats and fat-soluble vitamins. These fats are transported through the lymphatic system as chylomicrons before eventually entering the bloodstream.
Transportation of Immune Cells and Molecules: The lymphatic system transports immune cells, such as lymphocytes and antigen-presenting cells, throughout the body. It also carries antibodies, cytokines, and other immune molecules to sites of infection or inflammation, aiding in the immune response.
By performing these functions, the lymphatic system helps maintain fluid balance, supports immune responses, and facilitates the transport of essential nutrients throughout the body.
Step-by-step explanation:
I apologize for any confusion caused. The function of the lymphatic system is not solely to "recur" excess interstitial fluid to the blood, but rather to maintain fluid balance and support immune function. The lymphatic system collects excess interstitial fluid, known as lymph, from the tissues and returns it to the bloodstream. However, its role goes beyond fluid balance.but i mentioned some keys above !
