valves in the veins.
AV (Atrioventricular) Tricuspid between the right atrium and ventricle, Bicuspid (Mitral) between the left atrium and ventricle,
Semilinar valves = pulmonic valve between the right ventricle and the pulmonary trunk, Aortic valve between the left ventricle and aorta
valves
The tricuspid valve, the pulmonary valve, the mitral valve, and the aortic valve keep blood from flowing backwards inside the heart.
The Tricuspid valve
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.
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.
The blood in veins is not under direct pressure from the heart. It has little valves inside to prevent blood from flowing backwards away from the heart. These valves inside the veins prevent the backflow of blood in veins. They encourage the one-directional flow of blood to the heart.
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.
The aortic semilunar valve prevents backflow of blood from the aorta to the left ventricle.The aortic valve prevents backflow of blood from the aorta to the left ventricle of the heart.aortic valve
valves
Prevents backflow of blood from the pulmonary trunk (artery) into the right ventricle
The pulmonic valve prevents backflow of blood into the right 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.
An incompetent valve allows backflow of blood.
valves prevent the backflow of blood.

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.
It prevents blood flowing back into the heart from the arteries.
The papillary muscles and the chordae tendinae work to prevent prolapse of the AV valves. This prevents backflow of blood in the heart.
