Detailed explanation-1: -The apex of the heart is the very tip and helps pump or “wring out” blood from the ventricles to the rest of the body (LV apex) or the lungs (RV apex). It does this by helping regulate the right and left ventricles of the heart and allowing them to pump blood upward and out of the heart.
Detailed explanation-2: -The distal end of the heart is called the apex and lies directly superior to the diaphragm. The base is the uppermost and below the trachea. The great vessels enter and leave from the base. To pump blood through the arteries, capillaries, and veins to circulate oxygen, nutrients, and other substances.
Detailed explanation-3: -In the anatomical position, the apex of the heart is the confluence of the inferior and left borders. It is a projection inferiorly, anteriorly and to the left of the left ventricle. Anterolaterally, it is covered by the anterior surface of the mediastinal pleura.
Detailed explanation-4: -The apex (the most inferior, anterior, and lateral part as the heart lies in situ) is located on the midclavicular line, in the fifth intercostal space. It is formed by the left ventricle. The base of the heart, the posterior part, is formed by both atria, but mainly the left.
Detailed explanation-5: -The heart sits atop the diaphragm and its apex is close to the anterior surface of the thoracic cavity. With every beat, the heart twists forward and the apex taps against the chest wall, producing the apex beat.
