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.

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.
Where does the mitral valve allow blood to enter during contraction of left ventricle?
It blocks the backflow of blood from left ventricle to left atrium.
Where does blood flow from the right atrium?
right atrium --> tricuspid valve --> right ventricle --> pulmonary semilunar valve --> pulmonary arteries --> lungs --> pulmonary veins --> left atrium --> bicuspid valve --> left ventricle --> aortic semilunar valve --> aorta --> arteries and capillaries --> cells --> venules, veins, vena cava --> right atrium -->thoughtfulobserver
The valve located between the right ventricle and the pulmonary trunk is?
pulmonary semilunar valve
What event results in the pressure deflection called the dicrotic notch?
When the aortic semilunar valve snaps shut, a momentary increase in the aortic pressure results from the elastic recoil of the aorta after valve closure.
What comes after the aortic semilunar valve?
The blood flows through the aorta after exiting the left ventricle through the aortic valve.
What heart valve is located between the left ventricle and the aorta?
the aortic valveThe Aortic valveThe aortic semilunar valve lies between the left ventricle and the aorta.
Where is the aortic valve?
The aortic semilunar valve is located between the left ventricle and the aorta.
What valve prevents blood back flow from aorta to left ventricle?
Pulmonary semilunar valve (pulmonary valve)
What valve is at the entrance to the aorta?
The heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.
The valve that prevents blood from returning after the left ventricle has emptied itself is the?
Aortic semilunar valve
How many cusps does the aortic semilunar valve have?
There are three cusps in the aortic valve; the right, left and noncoronary cusps The aortic semilunar valve is composed of three cusps and opens only when the left ventricle contracts. I hope this helps
What guards the opening between left atrium and left ventricle?
Aortic Semilunar Valve
Which structure marks the end of the left ventricle and the entrance to the aorta?
aortic semilunar valve
What is the valve that prevents blood returning to the right ventricle after it pumps?
The aortic semilunar valve prevents backflow of blood from the aorta to the left ventricle.The aortic valve prevents backflow of blood from the aorta to the left ventricle of the heart.aortic valve
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.
Which heart valves prevent backflow into the ventricles?
The semilunar valves prevent backflow into the ventricles. The pulmonary semilunar valve prevents backflow in the right ventricle, and the aortic semilunar valve prevents backflow of blood in the left ventricle.
