Opis

The heart is a vital organ in the circulatory system, responsible for pumping blood throughout the body. It is a muscular organ located in the chest, slightly left of center. The primary function of the heart is to ensure the circulation of oxygen, nutrients, and hormones to various tissues and organs, while simultaneously removing waste products. Comprised of four chambers - the left and right atria and ventricles - the heart operates in a coordinated rhythmic pattern known as the cardiac cycle. This intricate process involves the contraction and relaxation of the heart muscle, facilitating the flow of blood through the arteries, veins, and capillaries. The heart plays a crucial role in maintaining homeostasis and sustaining life by supporting the delivery of essential elements required for cellular function and overall physiological well-being.
