The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
It is located on the diaphragmatic surface of the heart [1] [2] near the right margin. [2] It extends between the coronary sulcus and the (notch of [ 2 ] ) apex of the heart. It contains the posterior interventricular artery and middle cardiac vein .

The heart is a muscular organ found in humans and other animals. This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]
The right coronary sulcus begins anteriorly and superiorly on the sternocostal surface of the heart. Its position is marked by the location of the right coronary artery, and small cardiac vein. The right coronary sulcus separates the right atrium and its atrial appendage from the right ventricle inferiorly. The right coronary sulcus then passes ...
It is situated on the sternocostal surface of the heart, [1] [2] close to the left margin of the heart. [2] It extends between the coronary sulcus, and the apex of the heart; [1] upon reaching the diaphragmatic surface of the heart, it ends at the notch of cardiac apex. [3]
