The heart is a muscular organ located in the chest that pumps blood throughout the body, supplying oxygen and nutrients while removing waste products. It has four chambers: the right and left atria, and the right and left ventricles, which work together in a coordinated rhythm. The heart operates through a complex electrical system that regulates its contractions, and it is crucial for maintaining overall circulatory health. Additionally, it can be affected by various diseases, such as coronary artery disease and heart failure.
