Lymphatic capillaries collect tissue fluid or lymph from intercellular spaces, and larger lymph vessels drain into veins. This process helps regulate fluid balance by returning excess fluid from the extracellular space back into the blood, ensuring efficient circulation.

The lymphatic system plays a crucial role in maintaining fluid balance in the body. Lymphatic capillaries collect excess tissue fluid, known as lymph, from intercellular spaces. This fluid contains water, dissolved substances, and nutrients. As the lymph moves through larger vessels, it passes through lymph nodes where impurities and harmful microorganisms are filtered out. The lymphatic system then returns the filtered lymph, now purified, to the bloodstream, preventing the accumulation of excess tissue fluid. By aiding in the drainage of interstitial fluid, the lymphatic system helps regulate fluid balance, ensuring that cells receive essential nutrients and waste products are efficiently removed.
