Lymphatic system model. 18th-century wax model of a head and torso, showing the lymphatic system (white vessels). 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. This exhibit is part of the collections held at the Javier Puerta Museum of Anatomy, at the Faculty of Medicine of the Complutense University of Madrid, Spain.
