It manages body temperatures and water substance of body fluids and blood. This system contains of the heart, veins, and arteries. The heart is somewhat little and lays on the diaphragm which rests on the mediastinum and is located in the thoracic cavity. The mediastinum reaches out from the sternum to the vertebral column. From the first rib to the diaphragm and sits between the lungs. The heart has an apex which is the pointed end of a cone shaped structure, and a base which is the posterior part of the heart. The front surface of the heart is deep by the sternum and the ribs and the inferior surface of the heart is the apex and right surface and lays on the diaphragm. The heart is guarded by the ribs, lungs, and sternum as well as by pericardium. Pericardium holds the heart in its position in the mediastinum, yet permitting opportunity of development for compressions. The pericardium has two primary parts; serious pericardium (dense, inelastic, thick connective tissue) and serous pericardium (slender, more fragile film that form a double layer around the heart. The parietal layer of the serous pericardium is stuck on the fibrous pericardium and the visceral layer of the serous pericardium is one of the layers of the hearts
