The heart is the organ that helps supply blood and oxygen to all parts of the body. It is divided by a partition or septum into two halves‚ and the halves are in turn divided into four chambers. The heart is situated within the chest cavity and surrounded by a fluid filled sac called the pericardium. This amazing muscle produces electrical impulses that cause the heart to contract‚ pumping blood throughout the body. The heart and the circulatory system together form the cardiovascular system.

I. ANATOMY AND PHYSIOLOGY OF THE HEART I. LOCATION OF THE HEART The heart is located in the chest between the lungs behind the sternum and above the diaphragm. It is surrounded by the pericardium. Its size is about that of a fist‚ and its weight is about 250-300 g. Its center is located about 1.5 cm to the left of the midsagittal plane. Located above the heart are the great vessels: the superior and inferior vena cava‚ the pulmonary artery and vein‚ as well as the aorta. The aortic arch lies

ANATOMY AND PHYSIOLOGY OF THE HEART Anatomy: The heart and heart wall layers: The heart is located in the left side of the mediastinum; it consists of three muscle layers the Endocardium‚ myocardium‚ and epicardium. The epicardium is the outermost layer of the heart. The myocardium is the idle layer of and actual contracting muscle of the heart. The endocardium is the innermost layer and lines the inner chambers and heart valves. Pericardial sac: The pericardial sac encases and protects

ANATOMY AND PHYSIOLOGY OF HUMAN HEART The human heart is a cone shape‚ hollow‚ muscular organ located in the mediastinum between the lungs. It is a about the size of an adult fist. The heart rests on the diaphragm‚ tilting forward and to the left in the client’s chest. Each beat of the heart pumps about 60ml of blood‚ or 5L/min. During strenuous physical activity‚ the heart can double the amount of blood pumped to meet the increased oxygen needs of the peripheral tissues. ANTERIOR VIEW
