Anatomy and Morphology

of the human heart The human heart is an essential organ that pumps blood around the body, allowing us to live and survive. It is approximately the size of a fist and has four chambers, two upper (the atria) and two lower (the ventricles). The walls of the ventricles are thicker and more muscular than the walls of the atria, allowing them to pump the blood more forcefully. The heart also contains four main valves, which allow the blood to move between the different chambers and throughout the body. The anatomy and morphology of the human heart influences how it functions, and is important for diagnosing, assessing, and treating heart-related health issues.
