Vas Deferens

The ductus or vas deferens traverses superiorly from the testes. It is encased in the spermatic cord along with nerves and blood vessels. The ductus or vas deferens travels over the public symphysis. It then moves up and around the bladderA muscular organ that stores urine before excretion.. After that, it goes through the prostate gland and finally connects with the ureters. Sperm in the ductus (vas) deferens should be fully mature, with functional flagellaLong, whip-like structures used by some cells (e.g., sperm) for movement.. However, the ductus (vas) deferens is lined with pseudostratified ciliated columnar epithelial cells. The uniform waving motion of the ciliaHair-like projections on the surface of some cells that move fluids or particles. moves the sperm forward. Alternating contractions of the thick layer of smooth muscle surrounding the ductus (vas) deferens help propel spermatozoa. They push the sperm toward the urethraThe tube that carries urine from the bladder to the outside of the body..
