The uterus is the organ in a woman's body where an embryo grows during pregnancy. It provides a safe and nourishing environment for the embryo to develop into a fetus. Hormonal changes in the body during pregnancy support the growth and development of the embryo in the uterus.
An embryo forms first during pregnancy, after fertilization of the egg by sperm. It develops into a fetus around the end of the eighth week of pregnancy.
The organ that nourishes fertilized eggs is the uterus. After fertilization, the fertilized egg implants itself in the uterine lining, where it receives nutrients and oxygen through the placenta. The uterus provides a protective environment for the developing embryo and later the fetus throughout pregnancy.
