limf

Limf is a term encountered in several languages as a transliteration of the English word lymph. In English, the standard spelling is lymph, and the term refers to both the clear fluid that circulates through the lymphatic system and to the system itself.

Lymph originates as interstitial fluid that enters small lymphatic capillaries, forming lymph. It travels through progressively larger lymphatic vessels, passes through lymph nodes where immune cells monitor the content, and ultimately drains into the venous bloodstream via the thoracic duct and, on the right, the right lymphatic duct.

Key functions include maintaining fluid balance, facilitating immune surveillance by transporting lymphocytes and other immune cells, and, in the gut, absorbing dietary fats in the form of chyle.

Composition of lymph includes water, proteins, electrolytes, lipids in the form of chyle, and immune cells such as lymphocytes and macrophages.

Clinical relevance centers on the lymphatic system’s role in health and disease. Impaired lymph drainage can cause lymphedema; diseases of lymph nodes or vessels can arise from infections, malignancies, or congenital conditions. Diagnostic methods include lymphoscintigraphy, MRI, and other imaging techniques; treatments may involve compression therapy, physical therapy, and surgical options to restore or optimize lymphatic flow.
