nyirokútjain

Nyirokútjain refers to the lymphatic vessels in Hungarian. These vessels are a crucial part of the lymphatic system, which plays a vital role in the body's immune function and fluid balance. Lymphatic vessels form a network throughout the body, similar to blood vessels, but they carry lymph fluid instead of blood.

The lymph fluid originates from the interstitial fluid, the fluid that surrounds cells. As this fluid enters the lymphatic vessels, it is then called lymph. Lymph is a clear to yellowish fluid that contains white blood cells, particularly lymphocytes, which are essential for fighting infections. It also carries absorbed fats from the digestive system and waste products from the tissues.

The lymphatic vessels are thin-walled tubes that transport lymph towards the heart. They begin as tiny, blind-ended capillaries in the tissues. These capillaries merge to form larger vessels, which eventually converge into two main ducts: the thoracic duct and the right lymphatic duct. These ducts drain the lymph back into the bloodstream, typically near the collarbone. Along the path of the lymphatic vessels are lymph nodes, which act as filters, trapping bacteria, viruses, and other harmful substances. The movement of lymph through the vessels is aided by the contraction of surrounding muscles and the presence of valves that prevent backflow. Maintaining healthy lymphatic circulation is important for overall health and well-being.
