Human Heart The heart is a muscular organ that is situated in the front of the chest. It pumps blood all through the body in a process called circulation. Apart from the heart , the blood vessels and blood as a unit constitute the cardiovascular system. The heart cavity is divided down the middle into a right and a left heart, which in turn are subdivided into two chambers. The upper chamber is called an atrium (or auricle), and the lower chamber is called a ventricle. The heart is a muscular organ that serves to collect deoxygenated blood from all parts of the body, carries it to the lung s to be oxygenated and release carbon dioxide. Then, it transports the oxygenated blood from the lungs and distributes it to all the body parts [1] The heart pumps around 7,200 litres of blood in a day throughout the body [2] [3]. The heart is situated at the centre of the chest and points slightly towards the left. On average, the heart beats about 100,000 times a day ... The human heart is a complex organ featuring an intricate network of blood vessels, chambers, and supporting structures that work together to maintain circulation throughout the body. This detailed anatomical illustration showcases the heart 's major vessels, arteries, and veins, along with its essential structural components, providing a comprehensive view of cardiac anatomy from an anterior perspective.
