Topography and anatomy of the oviduct the chicken cross Highseks White

Female reproductive organs consist of ovaries and oviducts. The chicken oviduct is a long, winding tube that extends from the ovary to the cloaca and occupies most of the abdominal cavity. The oviduct is divided into five anatomical and functional parts: funnel, Magnum (protein Department), isthmus, uterus and vagina.

The vagina connects the uterus to the cloaca, through which the egg is excreted outside...
