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.
Aorta, arising from the left ventricle, ascending, arching, then descending through the thorax to the abdomen, where it divides into the common iliac arteries. abdominal aorta the distal part of the descending aorta, below the diaphragm; it is continuous with the thoracic aorta.onsists of four parts: the ascending aorta, the arch of the aorta, the thoracic portion of the descending aorta, and the abdominal portion of the descending aorta. Gives rise to the common carotid and subclavian arteries on the left side and to the brachiocephalic artery on the right side.
