The placenta is a specialized organ that develops during pregnancy and is responsible for providing the developing organism with oxygen and nutrients, as well as filtering away waste products. The ovum (or egg cell) is a female reproductive cell that is fertilized by sperm to initiate pregnancy. The umbilicus (or belly button) is the site where the umbilical cord, which connects the developing fetus to the placenta, is attached to the newborn after birth. The uterus is the muscular organ in which the fertilized egg implants, and in which the fetus grows and develops during pregnancy.
