What's the difference between ovary and ovulation?

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.

Ovulation


Definition:

  • (n.) The formation of ova or eggs in the ovary, and the discharge of the same. In the mammalian female the discharge occurs during menstruation.

Example Sentences:
