The lymphatic system plays an essential role in maintaining fluid balance, immune defense, and waste removal from the body. Its main functions include:
Step 1: Fluid Balance:
The lymphatic system helps to drain excess interstitial fluid from tissues and returns it to the bloodstream, thus preventing edema and maintaining the body’s fluid balance.
Step 2: Immune Function:
Lymph nodes filter lymphatic fluid to remove pathogens, debris, and foreign particles. Lymphocytes (T-cells and B-cells) within the lymph nodes play a crucial role in the body’s immune defense.
Step 3: Absorption of Fat:
The lymphatic system also absorbs dietary fats from the small intestine through specialized lymphatic vessels called lacteals, which transport the fats to the bloodstream.
Step 4: Waste Removal:
The lymphatic system assists in the removal of cellular waste products, such as dead cells, bacteria, and waste materials from tissues, ensuring their elimination from the body.
