ANATOMY

Detailed explanation-1: -Your tricuspid valve opens to let blood travel from your right atrium to your right ventricle. When your right ventricle is full it squeezes, which closes your tricuspid valve and opens your pulmonary valve. Blood flows through your pulmonary artery to your lungs, where it gets oxygen.

Detailed explanation-2: -The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart. From there, the blood flows through the tricuspid valve (TV) into the right ventricle (RV), or the right lower chamber of the heart.

Detailed explanation-3: -The tricuspid heart valve separates the right atrium from the right ventricle and allows deoxygenated blood to flow between them.

Detailed explanation-4: -Blood flows through the tricuspid valve into the right ventricle. It then flows through the pulmonic valve into the pulmonary artery before being delivered to the lungs.

Detailed explanation-5: -2. From the right atrium, blood flows through the tricuspid valve into the right ventricle.
