explain reproduction in human being. Why do testis lie outside the abdominal cavity.
Answers
Testis lies outside the body so that less temperature is maintained in the tests and sperm production is effective at that temperature Reproduction in human is a well defined one the reproductive events includes:formation of gametes,transfer of sperm,fusion of gametes, formation of zygote ,implantation then embryonic development finally parturition.
Reproduction means to reproduce young ones by parents.In human beings,two parents are required to reproduce,fusion of egg and ovum in correct time.Haploid gametes fuse to form diploid zygote.
Testis is located outside because it needs temperature 3-6 degree celcius less than body temperature for synthesis of sperms from spermatogonia.
