What's the difference between ovary and oviduct?

Ovary


Definition:

  • (n.) That part of the pistil which contains the seed, and in most flowering plants develops into the fruit. See Illust. of Flower.
  • (n.) The essential female reproductive organ in which the ova are produced. See Illust. of Discophora.

Oviduct


Definition:

  • (n.) A tube, or duct, for the passage of ova from the ovary to the exterior of the animal or to the part where further development takes place. In mammals the oviducts are also called Fallopian tubes.

Example Sentences:

  • (1) Scintigraphic pictures of the uterine cavity and oviducts were obtained with a Jumbo Toshiba gamma-camera; they were subsequently analysed by an Informatek SIMIS-3 data processing system.
