Any of the capillaries which lead from tissue and join lymphatic vessels.
One of the smallest lymphatic vessels. These thin-walled tubes consist of a single layer of endothelium ending blindly in a swollen or rounded end, and form a dense network in most tissues of the body. They are generally slightly larger in diameter than blood capillaries. Because they collect interstitial fluid, the composition of the lymph varies according to the tissue being drained. Intestinal lymphatics contain fatty materials during digestion; those from the liver contain proteins.
