in female mammals, the hollow muscular organ in which fertalized egg is embedded and in which the embryo and fetus develop
vagina
the canal in the female that extends from the vuvla to the cervix and that recieves the penis during sexual intercourse
vas deferns
a duct through which sperm move from the epididymis to the ejaculation duct at the base of the penis
