So fat must be absorbed via a different route: the lymphatic system. Lymphatic vessels are to blood vessels as Robin is to Batman. Every blood vessel inside the body is accompanied by a lymphatic vessel, even each tiny capillary in the small intestine. While our blood vessels are thick and red and heroically pump nutrients to our tissues, the lymphatic vessels are thin and filmy white in color. They drain away fluid that is pumped out of our tissue and transport the immune cells, whose job it is to ensure that everything is as it should be throughout the body.
