Reproduction in Organisms Test - 8

• Ovaries are the primary female sex organs that produce the female gamete (ovum) and several steroid hormones (ovarian hormones).

• The ovaries are located one on each side of the lower abdomen.

• The uterus opens into vagina through a narrow cervix. The cavity of the cervix is called cervical canal which along with vagina forms the birth canal.

• During birth, the baby passes through the birth canal.

• The oviducts (fallopian tubes), uterus and vagina constitute the female accessory ducts.

• Mons pubis is the external female genitalia.

• Mons pubis is a cushion of fatty tissue covered by skin and pubic hair.

Each ovary is covered by a thin epithelium which encloses the ovarian stroma. The stroma is divided into two zones – a peripheral cortex and an inner medulla.

The oviducts (fallopian tubes), uterus and vagina, constitute the female accessory ducts.

The female external genitalia include mons pubis, labia majora, labia minora, hymen and clitoris.

Hence, option D is the correct option.

The clitoris is a tiny finger-like structure which lies at the upper junction of the two labia minora above the urethral opening.

The cell of alveoli secretes milk, which is stored in the cavities of alveoli. The alveoli open into mammary tubules. The tubules of each lobe join to form a mammary duct.

Several mammary ducts join to form a wider mammary ampulla which is connected to the lactiferous duct through which milk is sucked out.
