|
|
|
opens in ventricular systole, when the pressure in the right ventricle rises above
|
|
|
closes off the lower left chamber that holds the oxygen-rich blood before it is pumped out to the body.
|
|
|
closes the artery in the lower right chamber in order to send oxygen to other parts of the body
|
|
|
opens the artery in order to prevent blood from entering the lungs

Detailed explanation-1: -When the left ventricle relaxes, the aortic valve closes and the mitral valve opens. This lets blood flow from the left atrium into the left ventricle. The left atrium contracts. This lets even more blood to flow into the left ventricle.
Detailed explanation-2: -During the contraction of the heart, the aortic valve typically opens three to five square centimeters. As the heart relaxes, this valve then closes and prevents leakage of blood from the ascending aorta backwards into the heart.
Detailed explanation-3: -It brings oxygenated blood from your heart to the rest of your body. The aortic valve prevents backward flow from the aorta into the left ventricle.
Detailed explanation-4: -The left ventricle generates the high pressure needed to pump the blood to your whole body through your blood vessels. When blood leaves the heart to go to the rest of the body, it travels through a large artery called the aorta. A balloon-like bulge, called an aortic aneurysm, can sometimes occur in the aorta.
