Reprinted courtesy of the Wilderness Society from The Living Wilderness, March 1980. In the history of American conservation, few have worked as long and as effectively to preserve wilderness and to articulate the âwilderness ideaâ as Ansel Adams.n a letter to Ansel in 1938 Stieglitz said, âIt is good for me to know that there is Ansel Adams loose somewhere in the world of ours.â Lovers of photography were not the only ones glad to have Ansel Adams loose in this world. Lovers of wilderness echoed this feeling.
The ascending aorta is the first part of the aorta, and begins at the aortic valve-located obliquely just to the left of the midline at the level of the the third intercostal space.he ascending aorta is the first part of the aorta, and begins at the aortic valve-located obliquely just to the left of the midline at the level of the the third intercostal space.
For the embryological structure, see Aortic arches. The aortic arch, arch of the aorta or the transverse aortic arch (English pronunciation: /eÉªËÉrtÉªk/) is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea.t this point the aortic arch continues as the descending aorta. The aortic arch has three branches. The first, and largest, branch of the arch of the aorta is the brachiocephalic trunk, which is to the right and slightly anterior to the other two branches and originates behind the manubrium of the sternum.
