lymfevæske

Lymfevæske, also known as lymph or lymphatic fluid, is a clear, colorless or slightly yellowish fluid that circulates within the lymphatic system. It plays a vital role in maintaining fluid balance in the body, transporting nutrients, and supporting immune function. Lymph originates from the interstitial fluid that surrounds tissue cells, collecting waste products, pathogens, and immune cells as it moves through tissues.

The lymphatic system comprises a network of vessels, lymph nodes, and organs such as the spleen and thymus. Lymphatic vessels carry lymph away from tissues toward the bloodstream, filtering it through lymph nodes that trap and destroy pathogens or foreign particles. Lymph contains various components, including lymphocytes (a type of white blood cell), proteins, fats, and cellular debris.

Lymfevæske is essential for immune surveillance, aiding in the detection and response to infections. It also plays a critical role in absorbing dietary fats from the gastrointestinal tract via specialized lymphatic vessels called lacteals. The composition and flow of lymph are regulated by muscle contractions, respiratory movements, and vessel valves to ensure unidirectional movement toward the venous circulation.

Disorders related to lymph or lymfevæske include lymphedema, characterized by abnormal swelling due to impaired lymph drainage, and infections such as lymphadenitis. Maintaining healthy lymphatic circulation is important for overall health, supporting immune defense and preventing fluid buildup.

In summary, lymfevæske is a crucial component of the lymphatic system, involved in fluid regulation, immune response, and nutrient absorption, contributing to the body's overall homeostasis.
