REPRODUCTIVE SYSTEM

The reproductive system allows humans to make more living things of the same type.
Everything starts with two cells: a sperm (made by the male reproductive organs) and an ovule or egg (made by the female reproductive organs).

Next video is the whole process of creating a new human: from fertilization to the newborn baby. A summary of the nine moths into 15 minutes!!!
