Final answer:
The apex of the heart, which points inferiorly toward the left hip, lies just to the left of the sternum and is related to the cardiac notch in the lung.
Step-by-step explanation:
The point of the heart that points inferiorly toward the left hip is known as the apex of the heart. The apex of the heart is the inferior tip, which lies just to the left of the sternum between the junction of the fourth and fifth ribs near their articulation with the costal cartilages. An important landmark in relation to the cardiac notch is that the cardiac notch, a depression in the medial surface of the inferior lobe of the left lung, accommodates the apex of the heart. Understanding the location of the heart's apex is crucial in clinical settings, particularly when placing a stethoscope on the chest to listen for heart sounds or when reviewing medical images.
