The part of the aorta that connects the ascending(just as it leaves the heart) with the descending aorta It is significant for two major reasons The major vessels to the head and arms branch off the aortic arch Baroreceptors and chemoreceptors are located on the aortic arch Press the "back" button to return to where you came from
Narrowing of the aortic valve opening, causing obstruction of blood flow into the circulation The condition causes the heart to work harder and the muscle in the wall of the left ventricle (lower chamber) to thicken
The aortic valve is the last valve through which the blood passes before it enters the aorta or main blood vessel of the body The valve prevents blood from leaking back into the left ventricle from the aorta after it has been ejected from the heart
Four valves are in the heart with two on the left side and two on the right side On each side there is an inflow valve to the ventricle - the main pumping chamber - and an outflow valve The aortic valve is the outflow valve for the left ventricle, and as such opens when the ventricle squeezes blood out and then closes to keep blood from leaking back into the ventricle
