A baby grows in the uterus, a muscular organ located in a woman's pelvis.
Understanding the Uterus
The uterus, often described as being shaped like an upside-down pear, is a vital part of the female reproductive system. Its muscular walls are designed to expand significantly during pregnancy to accommodate the growing fetus. After the baby is born, these muscles contract to help expel the placenta.

Several other sources corroborate this: The Nemours KidsHealth article on the female reproductive system explains that the uterus is where the fertilized egg (zygote) implants and develops into a baby. [Nemours KidsHealth link] ACOG's FAQ on fetal growth also identifies the uterus as the location of fetal development. [ACOG link] The Cleveland Clinic's description of the female reproductive system further emphasizes the uterus's role in pregnancy. [Cleveland Clinic link]
Fetal Development in the Uterus
Throughout pregnancy, the fetus grows and develops within the protective environment of the uterus, receiving nourishment and oxygen through the placenta and umbilical cord. Ultrasound technology allows medical professionals to monitor the fetus's growth and development inside the uterus. [ACOG link] The process of fetal development is complex and involves the formation of various body parts and organs. [MedlinePlus Fetal Development link] The stages of fetal development are well documented, and show progressive growth within the uterus from a single cell to a fully formed baby.
