.. atria during systole.
All the valves of the heart prevent backflow of the blood through the heart: tricuspid valve, pulmonary valve, mitral valve, and aortic valve. Furthermore, there are one-way valves in the veins that prevent backflow of blood.
The papillary muscles and the chordae tendinae work to prevent prolapse of the AV valves. This prevents backflow of blood in the heart.
ventricles
The semilunar valves prevent backflow into the ventricles. The pulmonary semilunar valve prevents backflow in the right ventricle, and the aortic semilunar valve prevents backflow of blood in the left ventricle.
Nothing, it is only pressure that keeps blood moving in the right direction in arteries. Veins have valves that prevent backflow of blood, but arteries do not.
Atrioventricular valves prevent backwards flow of blood inside the heart, i.e. flow from the ventricles back to the atria. Semilunar valves prevent backwards flow of blood into the heart from the aorta (left ventricle) or the pulmonary arteries (right ventricle).
yes, they get it back by pumping blood to the 4 parts of your heart. when you inhale, it makes rich blood when you exhale it takes out poor blood which turns into carbon dioxide.

The atrioventricular valves prevent the backflow of blood from the ventricles to the atria. They permit the one-directional flow of blood from the atria to the ventricles.
Valves prevent the backflow of blood
The part of the heart that prevents blood from flowing backward is primarily the valves. Specifically, the atrioventricular (AV) valves, which include the mitral and tricuspid valves, prevent backflow from the ventricles to the atria, while the semilunar valves (aortic and pulmonary valves) prevent backflow from the aorta and pulmonary artery into the ventricles. These valves ensure unidirectional blood flow through the heart and into the circulatory system.
valves prevent the backflow of blood.
When they are working properly, the four valves of the heart ensure one-way blood flow. The atrioventricular valves prevent backflow into the atria, and the semilunar valves prevent backflow into the ventricles.
