The vessels serve to deliver the blood to all locations within the body, and to return the blood back to the heart. Located within the thorax and rests upon the diaphragm. Parietal pericardium pericardial cavity/space (fluid filled) 3 layers: from the outside in: epicardium- visceral pericardium, myocardium, endocardium. Right and left atria(atrium) -receive blood from veins. Right and left ventricles -force blood out of the heart into arteries. Septum- separates the atria and ventricles on the left and right side. The heart pumps blood: to the lungs to pick up the oxygen, then, to the rest of the body. Closed loop of vessels carrying blood between heart and lungs systemic circulation.
