Origin of oviduct:
1830–40; < NL ōviductus. See ovi -, duct
Fallopian tube, uterine tube, oviduct(noun)
either of a pair of tubes conducting the egg from the ovary to the uterus
A duct through which an ovum passes from an ovary to the uterus or to the exterior.
In vertebrates, the passageway from the ovaries to the outside of the body is known as the oviduct. The eggs travel along the oviduct. These eggs will either be fertilized by sperm to become a zygote, or will degenerate in the body. Normally, these are paired structures, but in birds, crocodilians, and some cartilaginous fishes, one or the other side fails to develop, and only one functional oviduct is found. Except in teleosts, the oviduct does not directly contact the ovary. Instead, the most anterior portion ends in a funnel-shaped structure called the infundibulum, which collects eggs as they are released by the ovary into the body cavity. The only female vertebrates to lack oviducts are the jawless fishes. In these species, the single fused ovary releases eggs directly into the body cavity. The fish eventually extrudes the eggs through small genital pores towards the rear of the body.
