The female reproductive system consists of the following main organs:
- Uterus: Supports fetal development during pregnancy.
- Ovary: Produces eggs (ova) and hormones like estrogen and progesterone.
- Endometrium: The inner lining of the uterus, which thickens during the menstrual cycle to support embryo implantation.
- Cervix: A narrow passage between the uterus and vagina that allows the passage of sperm and menstrual blood.
- Vagina: Serves as the birth canal and receives sperm during reproduction.
Function: The female reproductive system plays a crucial role in reproduction, including egg production, fertilization, fetal development, and childbirth. A labelled diagram helps in understanding its structure.
