The vaginal artery is a branch of the internal iliac artery and is present in which sex?

• A. Male
• B. Female
• C. Both
• D. Neither

Answer: (B)

This item tests understanding of sex-specific pelvic blood supply. The vaginal artery, a branch of the anterior division of the internal iliac artery, supplies the vagina and nearby structures. Since the vagina is a female reproductive organ, this artery is present in females. In males, there is no vagina, and the vascular supply to pelvic organs comes from other branches (such as the inferior vesical, prostatic, and middle rectal arteries), so the vaginal artery is not a usual vessel in males. Therefore, the correct answer is the female.
