The upper portion is the larger part, and it is here where a fetus grows and is nourished during pregnancy. The uterus is very thick-walled and quite elastic, as is demonstrated by its ability to expand enough to hold a growing fetus, then return to approximately its prior size after the birth of the baby.

Reproductive System . Special note: The human body and reproduction involve highly personal information and topics. This page and all pages on this site are intended to supplement instruction and guidance from parents, schools and other responsible community organizations. The reproductive system is responsible for the creation of new life. Humans have sexual reproduction. This means that a male and female come together to form a new baby. Parts of the reproductive system. Gamete: The male or female sex cell that unite to form a zygote. Gonad: The major male or female reproductive organs that make the male and female sex cells (ovum and sperm). Puberty: This occurs around the preteen and teen years when males and females bodies mature and they become capable of creating new life.
