|
|
chamber in the heart that contracts and pushes blood through the tricuspid valve
|
Explanation:
Detailed explanation-1: -Blood first enters the heart’s right atrium. A muscle contraction forces the blood through the tricuspid valve into the right ventricle. When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs.
Detailed explanation-2: -Superior vena cava: Receives blood from the upper body; delivers blood into the right atrium.
Detailed explanation-3: -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.
