lümfijuhtmete

Lümfijuhtmed, also known as lymphatic vessels, are a crucial part of the lymphatic system. This intricate network of thin tubes runs throughout the body, working in tandem with the circulatory system. Their primary function is to transport lymph, a clear to yellowish fluid containing white blood cells, waste products, and other substances, from the body's tissues back to the bloodstream.

These vessels begin as tiny, blind-ended capillaries in the tissues, where they collect excess fluid and interstitial fluid, which then becomes lymph. The lymph then flows through progressively larger vessels, passing through lymph nodes. Lymph nodes are small, bean-shaped organs that filter the lymph, trapping bacteria, viruses, and other harmful substances. Immune cells within the lymph nodes can then identify and destroy these pathogens.

The lymphatic vessels eventually converge to form larger ducts, the thoracic duct and the right lymphatic duct. These major vessels empty the lymph back into the venous circulation, specifically into the subclavian veins near the heart. This continuous circulation of lymph is vital for maintaining fluid balance in the body, absorbing fats from the digestive system, and facilitating immune responses. Without healthy lümfijuhtmed, fluid would accumulate in the tissues, leading to swelling and compromising the body's ability to fight infection.
