Explain the relative dominance of the reproductive system to the digestive system in Ascaris (Nematode).

Solution

In ascaris all the organs required in reproductive system are present and well developed which includes testis, vas deferens, seminal vesicle, ejaculatory duct, cloaca and penial setae in male and ovaries, oviducts, uterus and vaginal opening in female.

While digestive system is not fully developed which contains mouth, pharynx, intestines, and rectum which all together is called as alimentary canal in which food enters from mouth and exits from anus, Canal is kind of tube in which food gets digested.

This digestive system lacks many essential organs such as stomach, which shows relative dominance of reproductive system to digestive system
