Reproductive System - A Key to Continuation of Generation
Reproductive system is one of the vital organs of body which is associated with the continuance of species. Many non-living fluids, hormones and pheromones are responsible for the success of activity of the reproductive system. Like different organs the sexes of different species are also an important part of reproductive system. The sexes of different species are identified by different characters that make them unique. This sexual dimorphism is responsible for the new genetic combinations as the genetic material of the two individuals is different which results in the offspring's fitness in the environment. The major human reproductive organs include the external genitalia which comprise the penis and the vulva along with internal organs which include the gamete producing gonads which include testis and ovaries.
