Which statement correctly describes the female reproductive system components?

• A. The uterus is round and has no cervix
• B. The ovaries are primarily muscular
• C. The vagina secretes insulin
• D. The uterus is pear-shaped with a body and a cervix

Answer: (D)

The main idea is the basic anatomy of the uterus and its parts. The uterus is pear-shaped and serves as the central organ of the female internal reproductive system. It has a large upper portion called the body (where implantation and development occur) and a lower portion called the cervix, which funnels into the vagina. This configuration—pear-shaped uterus with a distinct body and cervix—is the correct description. The other statements don’t fit the anatomy: the uterus isn’t round and doesn’t lack a cervix; the ovaries aren’t primarily muscular—they’re glandular structures that produce eggs and hormones; the vagina doesn’t secrete insulin—it’s a muscular canal that transports menstrual blood, receives the penis during intercourse, and forms part of the birth canal, with secretions to lubricate it.
