The female reproductive system has two ovaries (singular: ovary). These have two functions:

Each ovary is connected to the uterus by an oviduct.. The oviduct is lined with cilia, which are tiny hairs on cells. As part of the menstrual cycle, an ovum develops, becomes mature and is released from an ovary. The cilia move the ovum along the oviduct and into the uterus.

The uterus is a muscular bag with a soft lining. The uterus is where a baby develops until birth. The cervix is a ring of muscle at the lower end of the uterus. It keeps the baby in place during pregnancy.

The vagina is a muscular tube that leads from the cervix to the outside of the body. A penis goes into the vagina during sexual reproduction. This is also where menstrual blood leaves the body and where a baby exits during birth.
