Artery to the ductus deferens
Encyclopedia
The artery to the ductus deferens, as its name suggests, is an artery in males that provides blood to the vas deferens
.
. It accompanies the vas deferens
into the testis, where it anastomoses with the testicular artery
. In this way it also supplies blood to the testis and epididymis
.
A small branch supplies the ureter

Vas deferens
The vas deferens , also called ductus deferens, , is part of the male anatomy of many vertebrates; they transport sperm from the epididymis in anticipation of ejaculation....

Course
The artery usually arises from the anterior trunk of the superior vesical arterySuperior vesical artery
The superior vesical artery supplies numerous branches to the upper part of the bladder.From one of these a slender vessel, the artery to the ductus deferens, takes origin and accompanies the duct in its course to the testis, where it anastomoses with the internal spermatic artery.Other branches...

Testicular artery
The testicular artery is a branch of the abdominal aorta that supplies blood to the testis. It is a paired artery, with one for each of the testes....

Epididymis
The epididymis is part of the male reproductive system and is present in all male amniotes. It is a narrow, tightly-coiled tube connecting the efferent ducts from the rear of each testicle to its vas deferens. A similar, but probably non-homologous, structure is found in cartilaginous...

Ureter
In human anatomy, the ureters are muscular tubes that propel urine from the kidneys to the urinary bladder. In the adult, the ureters are usually long and ~3-4 mm in diameter....
