Pitvarokra

Pitvarokra is a Hungarian term that translates to "atria" in English, referring to the two upper chambers of the heart. These chambers are crucial for the circulation of blood. The right atrium receives deoxygenated blood from the body and pumps it into the right ventricle. Simultaneously, the left atrium receives oxygenated blood from the lungs and pumps it into the left ventricle. The coordinated contraction and relaxation of the atria and ventricles ensure the efficient flow of blood throughout the body.

The structure of the atria consists of muscular walls, with the right atrium being slightly larger than the left. They are separated by a thin wall called the interatrial septum. Within the atria, specialized cells called the sinoatrial (SA) node act as the natural pacemaker of the heart, initiating the electrical impulses that trigger the heartbeat. The atrioventricular (AV) node then relays these impulses to the ventricles, coordinating their contraction.

Diseases or abnormalities affecting the atria can have significant implications for cardiovascular health. Conditions such as atrial fibrillation, where the atria beat irregularly, can lead to blood clots and increase the risk of stroke. Understanding the function and anatomy of the pitvarokra is fundamental to comprehending the overall mechanics of the heart and diagnosing various cardiac conditions.
