THORAX ABDOMEN AND PELVIS

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 extends downward, to the left, ending in a blunt point called the apex, which is even with the fifth intercostal space. The apex points toward the left hip. Just below the left nipple, between the fifth and sixth ribs, theapi-cal impulse can easily be felt.

Detailed explanation-3: -The heart consists of four chambers: two smaller atria at the top (the base) and two larger ventricles at the apex. A band of fibrous tissue separates the atria from the ventricles and seats the four cardiac valves. A muscular septum separates the right from left atrium and the right from left ventricle.
