Document Summary
Hap201 week four chapter 20: the cardiovascular system the heart. Lo 20. 1: demonstrate the location of the heart with reference to surface landmarks. The heart rests on the diaphragm, near the midline of the thoracic cavity. The heart lies in the mediastinum, an anatomic region that extends from the sternum to the vertebral column, from the first rib to the diaphragm, and between the lungs. The pointed apex is formed by the tip of the left ventricle (a lower chamber of the heart) and rests on the diaphragm. It is directed anteriorly, inferiorly, and to the left. The base of the heart is opposite to the apex and is its posterior aspect. It is formed by the atria (upper chambers) of the heart, mostly the left atrium. The anterior surface is deep to the sternum and ribs. The inferior surface is the part of the heart between the apex and right surface and rests mostly on the diaphragm.
