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.

What organ system provides a developing fetus with nourishment? The reproductive system of the female, particularly the placenta which is attached to the uterine wall (the uterus). Maternal blood vessels are coiled up next to placental b â¦ lood vessels and nutrients and oxygen, as well as waste products from the developing fetus, pass the walls of both sets of vessels through a process known as osmosis.
