How does the uterus change and adapt during pregnancy to support the growing fetus"?
During pregnancy, the uterus undergoes significant changes to support the growing fetus. The uterus expands in size to accommodate the developing baby, its muscle walls thicken to provide support, and the blood supply to the uterus increases to supply nutrients and oxygen to the fetus. Additionally, the cervix softens and dilates to prepare for childbirth. These adaptations allow the uterus to provide a safe and nurturing environment for the growing fetus throughout pregnancy.
