Detailed explanation-1: -The right atrium and ventricle make up most of the sternocostal surface of the heart, while the diaphragmatic surface is made up by the right and left ventricles. The left atrium contributes to the anatomical base.
Detailed explanation-2: -It runs as far as the midclavicular line. Because this inferior border lies along the surface of the diaphragm, it is often referred to as the “diaphragmatic” surface. It is formed mainly by the right ventricle.
Detailed explanation-3: -The Conduction System Electrical impulses from your heart muscle (the myocardium) cause your heart to contract. This electrical signal begins in the sinoatrial (SA) node, located at the top of the right atrium. The SA node is sometimes called the heart’s “natural pacemaker.”
