Lümfivõrku

Lümfivõrku, also known as the lymphatic network, is a critical component of the lymphatic system in the body. It is a complex system of vessels that run throughout the body, parallel to the circulatory system. The primary function of the lümfivõrku is to transport lymph, a clear to yellowish fluid containing white blood cells, throughout the body.

This network begins with tiny, blind-ended lymphatic capillaries that collect excess interstitial fluid, also known as lymph, from tissues. As these capillaries merge, they form larger lymphatic vessels. These vessels eventually drain into larger lymphatic ducts, the two main ones being the thoracic duct and the right lymphatic duct. These ducts then empty the lymph back into the bloodstream, typically near the collarbone.

Along the pathways of the lümfivõrku are lymph nodes, small bean-shaped organs that act as filters. Lymph nodes house immune cells, such as lymphocytes and macrophages, which identify and destroy foreign substances like bacteria, viruses, and abnormal cells. Swollen lymph nodes can be an indication of an infection or other immune response.

The lümfivõrku plays a vital role in maintaining fluid balance by returning leaked plasma to the bloodstream, absorbing fats from the digestive system, and supporting the immune system's ability to fight off pathogens. Its intricate structure ensures the efficient movement of lymph and immune surveillance throughout the entire organism.
