Oviducts is a thin and coiled muscular tube with a funnel-shaped opening near the ovaries. It joins uterus to the ovary. The ovum (or egg cell) released by an ovary goes into the fallopian tube through its funnel-shaped opening. The fertilisation of egg (or ovum) takes place in the fallopian tube.
The Vas Defenders is a narrow duct which starts from testis and joins the urethra. It carries sperms to the urethra by the muscular action of its wall. Fluid produced by the seminal vesicles mixes with the sperms to produce semen. This fluid provides nourishment to the sperms.
