THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The left and right pulmonary surfaces are made up by the left ventricle and right atrium, respectively. Of note, the left pulmonary surface rests in the cardiac notch of the left lung. The heart is made up of four muscular chambers that work synergistically to propel blood throughout the body.

Detailed explanation-2: -The left ventricle is longer and more conical in shape than the right, and on transverse section its concavity presents an oval or nearly circular outline. It forms a small part of the sternocostal surface and a considerable part of the diaphragmatic surface of the heart; it also forms the apex of the heart.

Detailed explanation-3: -The lower left heart chamber is called the left ventricle. The left ventricle is the heart’s main pumping chamber. During left ventricular hypertrophy, the thickened heart wall can become stiff. Blood pressure in the heart increases. The changes make it harder for the heart to effectively pump blood.

Detailed explanation-4: -The ventricles are the two lower chambers of the heart, one on the right and one on the left. The ventricles receive blood from the heart’s upper chambers (atria) and pump it to the rest of the body. The right ventricle pumps blood to the lungs, and the left ventricle pumps blood to the rest of the body.
