Choose the correct statements with respect to the female reproductive system.
- The oviducts (fallopian tubes), uterus and vagina constitute the female accessory ducts.
- Each fallopian tube is about 10-12 cm long and extends from the periphery of each ovary to the uterus.
- Each ovary is about 2 to 4 cm in length and is connected to the pelvic wall and uterus by bone.
- Each ovary is covered by a thin epithelium which encloses the ovarian stroma. The stroma is divided into two zones – an inner cortex and a peripheral medulla.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 1 and 2
The female reproductive system has a pair of ovaries, the accessory ducts, and the external genitalia. Each statement below gives a fact about one of these parts.
1. The oviducts (fallopian tubes), uterus and vagina constitute the female accessory ducts. — True. These three tubes carry the ovum, hold the developing foetus and form the birth canal, so they are together called the female accessory ducts.
2. Each fallopian tube is about 10-12 cm long and extends from the periphery of each ovary to the uterus. — True. The fallopian tube runs from near the ovary to the uterus. Its funnel-shaped end near the ovary collects the ovum after ovulation.
3. Each ovary is about 2 to 4 cm in length and is connected to the pelvic wall and uterus by bone. — False. The size is right, but the ovary is held in place by ligaments, not by bone.
4. Each ovary is covered by a thin epithelium which encloses the ovarian stroma. The stroma is divided into two zones – an inner cortex and a peripheral medulla. — False. The two zones are the other way round. The stroma has a peripheral (outer) cortex and an inner medulla.

The Female Reproductive System – “… Each ovary is about 2 to 4 cm in length and is connected to the pelvic wall and uterus by ligaments. 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. Each fallopian tube is about 10-12 cm long and extends from the periphery of each ovary to the uterus …, the part closer to the ovary is the funnel-shaped infundibulum.”
