Aorta

(Taxon-specific: ) Heart. [Stachowitsch, 1992]
(Taxon-specific: ) Unpaired blood vessel extending ventroposteriorly from heart. Separated from heart by anteroventral aortic valve and splits distally into several branches. [Stachowitsch, 1992]
In circulatory system, major blood vessel exending from end of heart. One may distinguish 1) an unpaired anterior aorta extending into head and bearing a cor frontale and 2) paired posterior aortas extending to end of abdomen. [Stachowitsch, 1992]
In circulatory system, major blood vessel extending from end of heart. One may distinguish an anterior aorta extending into head and paired posterior aortas. Anterior aorta bears cor frontale.
See: Lateral artery [Stachowitsch, 1992]
Anterior aorta, dorsal aorta. [Stachowitsch, 1992]
In circulatory system, major blood vessel extending from end of heart. One may distinguish an anterior aorta extending into head and a paired or unpaired posterior aorta extending to end of abdomen. [Stachowitsch, 1992]
In circulatory system, major unpaired blood vessel extending from anterior end of heart. Extends into head and bears small accessory heart (corfrontale). [Stachowitsch, 1992]
In circulatory system, major blood vessel extending from heart. According to position one may distinguish an anterior aorta (bearing cor frontale), a posterior aorta, and a descending aorta. [Stachowitsch, 1992]
Major blood vessel leading from heart. According to position one may distinguish an anterior aorta (giving rise to antennal, antennular, opthalmic, and other cephalic arteries) and a posterior aorta. [Stachowitsch, 1992]
(Taxon-specific: Class Secernentea) In circulatory system, major unpaired blood vessel extending from end of heart. One may distinguish an anterior aorta extending into head and a posterior aorta extending into abdomen; each is branched distally. [Stachowitsch, 1992]
(Taxon-specific: Order Monhysterida) Unpaired dorsal blood vessel extending anteriorly from heart. [Stachowitsch, 1992]
(Taxon-specific: Family Cyatholaimidae) Unpaired dorsal blood vessel extending anteriorly from heart.
(syn. anterior aorta) [Stachowitsch, 1992]
In circulatory system of anaspidacean, major blood vessel extending from heart. According to position one may distinguish an anterior aorta extending into head, a posterior aorta extending into abdomen, and a descending aorta at level of eighth thoracic somite. (See also artery). [Stachowitsch, 1992]
In circulatory system, blood vessel extending from end of heart. One may distinguish short anterior and posterior aortas. [Stachowitsch, 1992]
Anterior aorta, descending aorta, posterior aorta. [Stachowitsch, 1992]
