Why are the valves at the start of the aorta called semilunar valves?
Because there are crescent shaped, like half moons :)
What events occur when the semilunar valves are open?
The semilunar valves are open when blood is being pumped by ventricular contraction. This event is called systole.
Are the tricuspid valves of the heart also called semilunar valves?
The tricuspid valves are different from the semilunar valves. The tricuspid valve is the right atrioventricular valve.
Pressure in the arteries that opposes the opening of the semilunar valves is called what?
afterload
Why are the valves at the entrance to the aorta and pulmonary artery called semilunar?

This heart chamber pumps blood through the aortic semilunar valve?
pulmonary semilunar valve
Damage to the semilunar valves on the left semilunar valve would interfere with blood flow to which vessel?
Damage to the left semilunar valve would interfere with blood flow to the aorta.
What two blood vessels contain semilunar valves?
Right at the very start of the aorta is the aortic valve and at the very start of the pulmonary artery is the pulmonart valve, each of which are semilunar. In the heart there are two semilunar valves that lad to blood vessels. The pulmonary semilunar valve leads to the pulmonary trunk, and the Aortic semilunar valve leads to the Aorta.
Blood leaves through the semilunar valve and goes into the?
Blood leaving the the right ventricle through the pulmonary semilunar valve moves toward the lungs. Blood leaving the left ventricle though the aortic semilunar valve moves toward every where but the lungs.
