Preferred Label : ductus arteriosus;
Uberon definition : A fetal blood vessel connecting the pulmonary artery with the descending aorta[MESH].
In the developing fetus, the ductus arteriosus is a shunt connecting the pulmonary
artery to the aortic arch. It allows most of the blood from the right ventricle to
bypass the fetus' fluid-filled lungs, protecting the lungs from being overworked and
allowing the left ventricle to strengthen. There are two other fetal shunts, the ductus
venosus and the foramen ovale[MP]. the fetal vessel that connects the left pulmonary
artery with the descending aorta; the ductus arteriosus normally regresses into a
fibrous cord, the ligamentum arteriousum after birth[MP];
Uberon synonym : ductus Botallo;
Uberon related term : ductus layton; Botallo's duct; arterial canal; ductus arteriosis; ductus botalli; arterial duct; ductus arteriosum; fetal ductus arteriosus;
Uberon Homology note : On the other hand, in the sister clade of the actinopterygians, the sarcopterygians,
the gill circulation is supplemented with lung ventilation. As a result, the pulmonary
artery and vein and a functional ductus arteriosus arose as a major evolutionary innovation
from the sixth arch, giving the organism a flexible shunt to balance blood supply
to and from gills and lungs according to environmental conditions.[well established][VHOG];
