A Comparative Histological Study of The Female Reproductive System in Two Types of Amniotic Animals

Abstract

The research aims to conduct a comparative histological study of the female reproductive system in two types of amniotes that live in the Iraqi environment include the local rabbit and the Japanese quail. The study was conducted from 3/1/2021 to 21/5/2021 in the College of Agriculture, Anbar University, and the College of Education for Pure Sciences, Anbar University. After the animals were dissected, tissue sections were prepared for all parts of the reproductive system in birds and rabbits and examined for comparison. The study showed that the female reproductive system in birds consists of a single ovary with a shape similar to a grape cluster consisting of some ovarian follicles and a genital duct consisting of the funnel, magnum, isthmus, uterus, and vagina. As for the female reproductive system in rabbits, it consists of a pair of oval-shaped ovaries and an egg duct consisting of the ampulla and isthmus, as for the uterus, it is of a bicornuate type, connected by the cervix and the vagina on the lower side. The study showed that there are many differences in the shape and structure of the ovaries and oviducts in rabbits and quails, and this is due to the differences in their reproductive functions (viviparous or oviparous, respectively).
