Pulmonary valve and Aortic valve
During systole, the aortic and pulmonic valves open to permit ejection into the aorta and pulmonary artery.
<h3>What happen when ventricles contract ?</h3>
When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery
- Then it travels to the lungs. In the lungs, the blood receives oxygen then leaves through the pulmonary veins. It returns to the heart and enters the left atrium.
- When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta. The aorta and its branches carries the blood to all the body's tissues.
