Hint: Female reproductive system gives birth to new baby, it produces egg (ova), it produces sex hormones (estrogen, progesterone), support and protect developing embryo. Major organs are cervix, vagina, ovaries (gonads), uterine tubes (fallopian tubes) and uterus.
Complete Answer:
- Vagina is internal genitalia. Vagina is muscular, rigid sheath connecting the external genitals to the uterus. Function as a two- way street, accepting the penis and sperm during intercourse. Serving as the course of birth through which the new baby enters the world.
- Cervix is lined mucus, known as cervical mucus. Cervix mucus provides lubrication and sperm transport during sexual intercourse. At the end of pregnancy, Cervix acts as a passage through which the baby exits the uterus into vagina. The cervix canal expands to roughly times its normal width for the passage of the baby during birth.
- Ovaries produce eggs (also called ova) every female is born with a lifetime supply of eggs.
- Uterus is a pear- shaped muscular organ in the female reproductive tract. The fundus in the upper portion of the uterus where pregnancy occurs. Uterus expands considerably during the reproductive process.
Thus, the option (A) is correct.
Note: Female reproductive system has external genitalia, internal genitalia and accessory reproductive organs. External genitalia act as enabling sperm to enter into the body, protecting the internal genital organs from infectious organisms. Clitoris is the most sensitive protrusion; it is used for stimulation and can become erect.
