Los ovarios contienen alrededor de medio millón de óvulos inmaduros todos los óvulos que una mujer alguna vez tendrá se producen cuando ella aún es un feto. Producen las hormonas estrógeno y progesterona

29 trompas de falopio (oviductos)
Las trompas de Falopio son responsables de: Recoger al óvulo recientemente liberado. Proveerle al óvulo nutrientes y movimiento. Trasportar el espermatozoide hasta el óvulo. Mantener un ambiente adecuado para la fertilización. Trasladar un óvulo fecundado dentro del útero.

30 útero El útero es el órgano hueco, con forma de pera ubicado en el centro inferior de la pelvis de una mujer. El revestimiento uterino, conocido como endometrio, se forma durante la fase proliferativa del ciclo menstrual antes de recibir un embrión fecundado desde la trompa de Falopio. Es donde vive el fetus durante el embarazo

31 El Cuello de Utero o Cervix
que es un conducto que conecta con la vagina

32 La Vagina es el órgano de la copulación (junto con el vestíbulo y la vulva), cumpliendo el papel de recibir el pene durante el coito; la parte inferior del canal del parto. Es un conducto fibromuscular elástico. En las hembras de los mamíferos (el ser humano incluido), se extiende desde el vestíbulo vaginal hasta el cérvix uterino.
