Identify the odd one from the following:

The correct answer is Labia minora.

​​Explanation:

• The female reproductive system comprises a pair of ovaries, a pair of Fallopian tubes, a uterus followed by a cervix, a vagina, and external genitalia (consisting of Mons pubis, Labia majora, Labia minora, hymen, and clitoris).

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

Oviducts or the Fallopian tubes have three regions:

• Infundibulum: It is a funnel-shaped part that has finger-like projections called fimbriae which help in collecting the ovum during ovulation.
• Ampulla: Fertilization takes place in the ampulla of the oviduct.
• Isthmus: The last part of the oviduct, isthmus has a narrow lumen and it joins the uterus.

The labia minora is a part of the external female genitalia and represents the paired folded tissue present beneath the labia majora and surrounds the opening of the vagina.
