 | | The cardiovascular system consists of a muscular pump, the heart, in a double circuit of pipes that carry blood from the heart to the lungs and back in one circuit, the pulmonary circulation, and to the rest of the body and back to the heart, the systemic circulation. |
 | | Lymph capillaries are also important in the absorption of fat in the intestines and in fighting infection throughout the body by the contribution of immunologic factors and lymphocytes. |
 | | Injury or failure of the cardiovascular system, especially the heart, is a critical problem in that peripheral tissues depend on the delivery of nutrients and the removal of wastes through the blood vascular system. |
