aorta    音标拼音: [e'ɔrtə]
n. 大动脉

大动脉

aorta
n 1: the large trunk artery that carries blood from the left
ventricle of the heart to branch arteries

Aorta \A*or"ta\, n. [NL., fr. Gr. ?, fr. ? to lift, heave.]
(Anat.)
The great artery which carries the blood from the heart to
all parts of the body except the lungs; the main trunk of the
arterial system.
[1913 Webster]

Note: In fishes and the early stages of all higher
vertebrates the aorta divides near its origin into
several branches (the aortic arches) which pass in
pairs round the [oe]sophagus and unite to form the
systemic aorta. One or more pairs of these arches
persist in amphibia and reptiles, but only one arch in
birds and mammals, this being on the right side in the
former, and on the left in the latter.
[1913 Webster]
[1913 Webster]
