About

It is located in the chest and is responsible for supplying oxygen and nutrients to all tissues and organs, while also removing waste products. The heart is a muscular organ with four chambers - two atria and two ventricles - that work together in a synchronized contraction and relaxation process, known as the cardiac cycle, to ensure efficient blood flow. Additionally, the heart is regulated by electrical signals that maintain its rhythm and control its rate. Various conditions and diseases can affect the heart's function, leading to potentially serious health issues. Therefore, understanding the structure and function of the heart is essential in maintaining cardiovascular health.
