Human lymphatic system. Artwork of a front view of a human, showing the lymphatic system (yellow). Also seen are associated organs including the spleen (centre right). Beneath the skin runs a network of lymph vessels (lines) that serve lymph nodes or glands (rounded). There are groups of nodes in the neck, armpits, groin, and abdomen. This system functions to drain fluid (lymph) from body tissues and has a role in the absorption of fats from the intestine. The lymphatic system also plays a vital role in the body's immune system.
