During ventricular systole both ventricles contract, forcing the blood out of them and into another vessel. The left ventricle is the one that provides blood to the rest of the body. As it contracts, the high pressure causes the aortic semilunar valve to open, and blood travels through it to the aorta.
the four valves in the heart are
-tricuspid
-pulmonary semi-lunar
-bicuspid
-aortic semi-lunar
the aortic semi-lunar is valve the blood flows through when the described circumstance occurs but both of the semi-lunar valves open and close at the same time because both ventricles pump simultaneously
The left Ventricle dos that it gos from the left atrium to the left Ventricle in the aotra
left to right
yes
Semilunar valves are located at the base of both the pulmonary trunk (pulmonary artery) and the aorta
There are not valves in the pulmonary artery or the aorta. However there are valves between these and the heart. Between the right ventricle and the pulmonary artery there is a valve referred to as the pulmonary semilunar valve. Between the left ventricle and the aorta there is a valve called the aortic semilunar valve.
The entrance to the ascending aorta is guarded by the semilunar valve. The semilunar valves are pocketlike structures attached at the point at which the pulmonary artery and the aorta leave the ventricles.
Because there are crescent shaped, like half moons :)
No. No artery has valves, except for the aorta.
false
yes
false
Both these valves are halfmoon shaped
pulmonary and aorta valves.
veins
prevent the back flow of blood from ventricle to aorta
semi-lunar valves
