Aorta

The aorta (/ˈɔːrtə/) is the main artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.

Structure

Sections

In anatomical sources, the aorta is usually divided into sections.

One way of classifying a part of the aorta is by anatomical compartment, where the thoracic aorta (or thoracic portion of the aorta) runs from the heart to the diaphragm. The aorta then continues downward as the abdominal aorta (or abdominal portion of the aorta) diaphragm to the aortic bifurcation.

Another system divides the aorta with respect to its course and the direction of blood flow. In this system, the aorta starts as the ascending aorta then travels superiorly from the heart and then makes a hairpin turn known as the aortic arch. Following the aortic arch, the aorta then travels inferiorly as the descending aorta. The descending aorta has two parts. The aorta begins to descend in the thoracic cavity, and consequently is known as the thoracic aorta. After the aorta passes through the diaphragm, it is known as the abdominal aorta. The aorta ends by dividing into two major blood vessels, the common iliac arteries and a smaller midline vessel, the median sacral artery.

Aorta (band)

Aorta were an American psychedelic rock band from Chicago who recorded two albums in the late 1960s and early 1970s.

History

The band developed from a soul, pop and rock'n'roll group who had originally formed in Rockford, Illinois in 1962 as Kal David and the Exceptions. Its members were Kal David (b. David Raskin - vocals and guitar), Peter Cetera (bass, vocals), Denny Ebert (drums, vocals), and Marty Grebb (saxophone, keyboards, guitar, vocals). David left in 1965, to join The Rovin' Kind, later to become Illinois Speed Press, and was replaced by James Vincent (b. James Vincent Dondelinger, 8 February 1943, in Chicago; later known as Jim Donlinger). The band was then known as The Exceptions. They released several singles on local labels, and an EP, Rock and Roll Mass, on the Flair label, before Grebb left to join The Buckinghams, being replaced by Jim Nyeholt. Ebert also left to be replaced by Billy Herman. As The Exception, Vincent (Donlinger), Cetera, Nyeholt and Herman recorded several singles for Capitol Records, but Cetera left when the other members expressed a desire to perform more psychedelic material. Cetera joined The Big Thing, who became Chicago Transit Authority and then Chicago.

You say you're not tired of talking
But you don't know what to say
You have the winning score
If i would play the game
But the man from behind the future's talking
Begging you to find
Keep from what tomorrow's asking
But it's much too high to pay
Sleep tight, don't you worry
Everything will be all right
Sleep tight, don't you worry
You don't have a dream tonight
You send the card and invitations
But there's no one going to come
I know, you want to cry
But you'ru not there
Sleep tight, don't you worry
Everything will be all right
Sleep tight, don't you worry
You don't have a dream tonight
Time and time again you went everywhere you could
No one's ever seen you looking backwoods
You say a little extra time is all you need to save your soul
But your story's getting old
Now i'll have to close the line
