ductus arteriosusn.

Brit.

/ˌdʌkttəs ɑːtɪərɪˈəʊsəs/, U.S.

/ˈdək(t)əs ˌɑrtɪriˈoʊsəs/

Origin: A borrowing from Latin. Etymon: Latin ductus arteriosus.

Etymology: < post-classical Latin ductus arteriosus (1711 or earlier) < classical Latin ductus ductus n. + post-classical Latin arteriosus arterious adj.An earlier post-classical Latin and scientific Latin name for this structure is canalis arteriosus (1628 or earlier).

Anatomy and Zoology.

A short, wide blood vessel that connects the pulmonary artery with the aorta in fetuses and embryos of amniote vertebrates, allowing blood to bypass the non-functional lungs, and normally closing irreversibly to form a fibrous ligament soon after birth. Also: a similar connection in amphibian larvae, which may retain some degree of patency in adult life.
