Aorta

(Taxon-specific: Order Cladocera) Heart. [Stachowitsch, 1992]
(Taxon-specific: Order Cladocera) Unpaired blood vessel extending ventroposteriorly from heart. Separated from heart by anteroventral aortic valve and splits distally into several branches. [Stachowitsch, 1992]
(Taxon-specific: Order Cumacea) 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]
(Taxon-specific: Order Tanaidacea) 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]
(Taxon-specific: Order Decapoda) Anterior aorta, dorsal aorta. [Stachowitsch, 1992]
(Taxon-specific: Order Amphipoda) 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]
(Taxon-specific: Order Isopoda) In circulatory system, major unpaired blood vessel extending from anterior end of heart. Extends into head and bears small accessory heart (corfrontale). [Stachowitsch, 1992]
(Taxon-specific: Order Mysida) 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]
(Taxon-specific: Order Stomatopoda) 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: Order Leptostraca) 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: Subclass Branchiura) Unpaired dorsal blood vessel extending anteriorly from heart. [Stachowitsch, 1992]
(Taxon-specific: Subclass Copepoda) Unpaired dorsal blood vessel extending anteriorly from heart.
(syn. anterior aorta) [Stachowitsch, 1992]
(Taxon-specific: Superorder Syncarida) 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]
(Taxon-specific: Order Thermosbaenacea) In circulatory system, blood vessel extending from end of heart. One may distinguish short anterior and posterior aortas. [Stachowitsch, 1992]
(Taxon-specific: Order Euphausiacea) Anterior aorta, descending aorta, posterior aorta. [Stachowitsch, 1992]
