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.

Female Reproductive System Structures. 1. ovary -- (females have two of these) -- produce female gametes or eggs and the hormone estrogen. 2. oviduct (fallopian tube) -- carries the egg away from the uterus. -- internal fertilization normally occurs here.3. uterus -- implantation and development of the embryo and fetus before birth occurs here. 4. vagina or birth canal -- entry point for sperm from the male and exit tube for the baby when it is born.emale Reproductive System Structures. 1. ovary -- (females have two of these) -- produce female gametes or eggs and the hormone estrogen. 2. oviduct (fallopian tube) -- carries the egg away from the uterus. -- internal fertilization normally occurs here.
