Draw the female reproductive system cockroach?

Explanation

The female reproductive system of cockroach consists of a pair of ovaries, vagina, genital pouch, colleterial glands, spermathecae and the external genitalia.
2. A pair of ovaries lies laterally in the 2nd and 6th abdominal segnment.
3. Each ovary is formed of a group of eight ovarian tubules or ovarioles, containing a chain of developing ova.
3. The lateral oviducts of each ovary unite into a broad median common oviduct known as vagina, which opens into the genital chamber.
5. The vertical opening of the vagina is the female genital pore.
6. A pair of spermathecae is present in the 6th segment, which opens by a median aperture in the dorsal wall of the genital pouch.
7. During copulation, the ova descend to the genital chamber, where they are fertilized by the sperms.
8. A pair of white and branched colleterial glands present behind the ovaries forms a hard egg case called Ootheca around the eggs. Genital pouch is formed by the 7th 8th and 9th abdominal sterna.
9. The genital pouch has two chambers, a genital chamber into which the vagina opens and an oothecal chamber where oothecae are formed,
10. Three pairs of plate like chitinous structures called gonapophyses are present around the female genital aperture. These gonapophyses guide the ova into the ootheca as ovipositors.
11. Ootheca is a dark reddish to blackish brown capsule contains nearly 16 fertilized eggs and dropped or glued to a suitable surface, of high relative humidity near a food source.
