Ventrikler

Ventrikler are the lower chambers of the heart, comprising the right and left ventricles. These muscular chambers play a crucial role in the circulatory system by responsible for pumping blood out of the heart to various parts of the body. The right ventricle pumps deoxygenated blood into the pulmonary artery, which leads to the lungs for oxygenation. The left ventricle, significantly thicker and more muscular, pumps oxygenated blood into the aorta, distributing it throughout the body.

Anatomically, the ventricles are separated by the interventricular septum, a thick wall that provides structural support and prevents the mixing of oxygen-rich and deoxygenated blood. The walls of the ventricles contain thick cardiac muscle tissue, known as myocardium, necessary for generating the force required to circulate blood effectively.

During the cardiac cycle, the ventricles contract in a phase called systole, propelling blood into the arteries. This is followed by diastole, during which the ventricles relax and fill with blood from the corresponding atria. Proper functioning of the ventricles is essential for maintaining adequate blood flow, blood pressure, and overall cardiovascular health.

Ventricular dysfunction can lead to various heart conditions such as heart failure, ventricular hypertrophy, or cardiomyopathies. Diagnosis and management of ventricular-related issues are critical components of cardiology, often involving imaging techniques like echocardiography, MRI, and other diagnostic tools. Overall, the ventricles are vital for sustaining life through their continuous and robust contribution to blood circulation.
