Read remaining answer here. Also to know is, what prevents backflow into right atrium?
The tricuspid valve regulates blood flow between the right atrium and the right ventricle. It prevents the backflow of blood to the right atrium when the right ventricle pumps blood to the lungs. The mitral valve regulates the blood flow between the left atrium and the left ventricle.
Beside above, where does blood go when the right ventricle contracts? Blood passes from the right atrium through the tricuspid valve and into the right ventricle. When the right ventricle contracts, the muscular force pushes blood through the pulmonary semilunar valve into the pulmonary artery. The blood then travels to the lungs, where it receives oxygen.
Also Know, which heart valves prevents backflow into the right atrium?
The tricuspid valve is the three-leaflet valve on the right side of the heart between the right atrium and the right ventricle and stops the backflow of blood between the two.
Why do the right atrium and right ventricle contain oxygen poor blood?
The right atrium receives oxygen-poor blood from the body through the superior vena cava and the inferior vena cava and pumps the blood to the right ventricle. The pulmonary artery carries oxygen-poor blood to the lungs to receive oxygen. The pulmonary veins carry oxygen-rich blood from the lungs to the left atrium.
