ventriklerna
Ventriklerna, also known as ventricles, are four chambers of the heart that play a crucial role in the circulatory system. They are responsible for pumping blood throughout the body. The heart has two upper chambers called atria and two lower chambers called ventricles. The right atrium receives oxygen-depleted blood from the body and pumps it into the right ventricle. The right ventricle then pumps the blood to the lungs, where it is oxygenated. The left atrium receives oxygenated blood from the lungs and pumps it into the left ventricle. The left ventricle is the strongest and most muscular of the heart chambers, as it pumps oxygenated blood to the rest of the body through the aorta. The coordinated contraction and relaxation of the ventricles ensure the efficient circulation of blood, maintaining homeostasis in the body.
