The 'heart' is our organ, whose main task is to pump blood, which moves oxygen-rich blood and nutrients to our body through the circulatory system. With its strong muscle structure, it is a non-stop pump that contracts 60-80 times per minute and pumps approximately 4-6 liters of blood to the organs. The most important system it works with is the 'vascular system'. It collects the blood from our body with the venous system, sends it to the lungs for oxygenation, and pumps the oxygen-rich blood back to our body through the arteries. The Department of Cardiovascular Surgery is the medical unit that carries out the treatment of diseases (congenital or acquired) related to the heart and the vascular system it works with, with drugs or surgery.
