The correct spelling is "regurgitation."
The atrioventricular valves prevent the backflow of blood into the atria when the ventricles are contracting. The semilunar valves prevent backflow from the arteries into the ventricles.
That is the correct spelling of "regurgitate" (cough up or spit up).
semilunar valves are called semilunar because they look like half a moon. If something is not full in biology it is called 'semi' and lunar means the moon. So basicaly its called that because the valve looks like a half moon.
Those are called the semilunar lines.
the function of the semilunar valves are that they provied the lungs with glucose and oxygen
Mitral regurgitation
pulmonary semilunar valve
Damage to the left semilunar valve would interfere with blood flow to the aorta.
aortic stenosis, aortic regurgitation and mitral regurgitation
The correct answer is between the right ventricle and pulmonary trunk.
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.
