ANATOMY

Detailed explanation-1: -Anatomically speaking, the heart’s apex is the bottom tip of the heart, consisting of the left and right ventricles. Conditions affecting the heart’s apex include myocarditis, cardiomyopathy, and heart attack. Experts define the apex of the heart by the left ventricular (LV) apex and the right ventricular (RV) apex.

Detailed explanation-2: -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-3: -Every heart has 4 chambers. The two upper chambers are called the atria (left and right). The lower two chambers are your ventricles (left and right).

Detailed explanation-4: -The apex of the heart is its sharpest point; it is located at the bottom of the heart, angled down and forward. The base of the heart is its superior aspect, but the base still retains a support function as it connects the heart to suspensory tissues.

Detailed explanation-5: -The base of the heart is located at the level of the third costal cartilage, as seen in Figure. The inferior tip of the heart, the apex, lies just to the left of the sternum between the junction of the fourth and fifth ribs near their articulation with the costal cartilages.
