[Answer] What do the AV nodes do?

Answer: They prevent backflow into the atria when the ventricles contract




Most relevant text from all around the web:


What do the AV nodes do? The AV node is a very important part of the heart’s electrical system. It transmits the heart’s electrical signal from the atrium to the ventricle optimizes the coordination of each heartbeat and if atrial fibrillation occurs protects the ventricles from being bombarded with a … The atrioventricular node or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart. It electrically connects the atria and ventricles. The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus and conducts the normal electrical impulse from the atria to the ventricles. The AV node is quite compact (~1 x 3 x 5 mm). Tue Dec 04 2018 · Electrical signals from the atria must pass through the AV node to reach the ventricles . The AV node which controls the heart rate is one of the major elements in the cardiac conduction system. The AV node serves as an electrical relay station slowing the electrical current sent by the sinoatrial (SA) node before the signal is permitted to pass down through to the ventricles. Thu Jul 18 2019 · Atrioventricular (AV) Node The atrioventricular node lies on the right side of the partition that divides the atria near the bottom of the right atrium . When the impulses generated by the SA node reach the AV node they are delayed for about a tenth of a second. The AV or atrioventricular node is part of the electrical system of your heart and conducts electrical signals from the upper part or atria to the lower part or ventricles . Watch this animation to see the atrioventricular node in action....
