pulmonary vein

Answer 1

Right atrium

pulmonary artery

The right atrioventricular valve is the tricuspid valve. The tricuspid valve is located between the right atrium (top chamber) and right ventricle (bottom chamber). Its role is to make sure blood flows in a forward direction from the right atrium to the ventricle. It functions as a one-way valve that closes during ventricular systole to prevent regurgitation of blood from the right ventricle back into the right atrium. It opens during ventricular diastole, allowing blood to flow from the right atrium into the right ventricle.

In the normal course, blood passes from the right atrium through the tricuspid valve 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.
