szívkamrák

The szívkamrák, or heart ventricles, are the two lower chambers of the heart responsible for pumping blood out to the rest of the body. The right ventricle pumps deoxygenated blood to the lungs, while the left ventricle pumps oxygenated blood to the systemic circulation. These chambers are crucial for maintaining blood flow and oxygen delivery throughout the organism.

The right ventricle receives deoxygenated blood from the right atrium and pumps it through the pulmonary artery to the lungs for oxygenation. The left ventricle, which is the larger and more muscular of the two ventricles, receives oxygenated blood from the left atrium and pumps it into the aorta, the main artery of the body, to distribute it to all organs and tissues. The thick walls of the left ventricle are necessary to generate the high pressure required for systemic circulation.

The coordinated contraction and relaxation of the szívkamrák, along with the atria, constitute the cardiac cycle, which is essential for life. Any dysfunction in the ventricles, such as weakened pumping ability or abnormal thickening of their walls, can lead to serious cardiovascular conditions like heart failure or arrhythmias. Understanding the structure and function of the szívkamrák is fundamental to comprehending the overall mechanics of the heart.
