"understanding the heart"

The heart is a vital organ in the human body, responsible for pumping blood through the circulatory system to deliver oxygen and nutrients to tissues and remove waste products. Located in the chest, slightly to the left, the heart consists of four chambers: two atria and two ventricles. It works as a muscular pump, with electrical impulses coordinating the heartbeat. The heart plays a crucial role in maintaining the body's overall function and health, and any disturbance in its rhythm or structure can lead to serious health conditions, making it essential to monitor heart health throughout life.
