A great way to determine whether you a hot air balloon ride is for you is to try a tethered balloon ride at a fair or publicity event. In a tethered ride, balloons are anchored and pilots simply fly the balloon up and down with passengers in tow. Rides are short and last just a few minutes each.
The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle, the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve. Three leaflets on the aortic valve open and close with each heartbeat to allow one-way flow of blood. The aorta is a tube about a foot long and just over an inch in diameter.
The aorta is the central conduit from the heart to the body. Three great vessels arise from the top of the aortic arch. On the right is the innominate artery, which divides into the right subclavian artery and the right common carotid artery for the head and neck.he aorta has a thick wall, with three layers of muscle that allow the blood vessel to withstand the high pressure that is generated when the heart pumps blood to the body. The three layers are the tunica intima, tunica media, and the tunic adventitia.
