Hi today i´m going to talk about the humnas reproduction.

The important parts of the male: the male parts are the peins and the testes having the testes outside the abdomen facilitates the temperature regulation of the sperm which require especific temperatures to survive.

The female parts: vagina and uterus which act as the receptacle for the cemen, and the ovaries, which produce the females ova.

sex organissims are called gametes. In human beings the male sex cells are called sperm and the female sex cells are called egg or ova.

sexual reproduction happened when a male and a female gamate joins this fussion of gamates is called fertilization sexual reproduction allows some of the genetic in information from both parents mix, producing a offspring remsamble their parts but the kids are not identical to them. all living things reproduce by sexualy.
