chyle The milky fluid which travels in the lymphatic vessels draining the small intestine. It contains most of the products of digestion of the fat content of a meal, which are absorbed into the microscopic lacteals in the villi that project from the intestinal lining. Chyle is a particular type of lymph — the general term for fluid drained from body tissues; it flows into progressively larger channels to join lymph from other parts of the body in the thoracic duct in the chest, and thence reaches the bloodstream.
