Question 21 • 2026-2027 EDGE Human Anatomy and Physiology A
Some organs of the integumentary system include skin, hair, and nails. The cardiovascular system includes the heart, veins, and arteries. Which best describes the relationship of the integumentary system to the cardiovascular system?
Answer
A
The hair of the integumentary system is intermediate to the veins of the cardiovascular system.
B
The hair of the integumentary system is superficial to the veins of the cardiovascular system.
C
The hair of the integumentary system is proximal to the veins of the cardiovascular system.
D
The hair of the integumentary system is distal to the veins of the cardiovascular system.
Explanation
Superficial means closer to the body’s surface, while deep means farther inside. Hair is at the surface of the body, and veins lie beneath the skin, so the hair is superficial to the veins. The best choice is “The hair of the integumentary system is superficial to the veins of the cardiovascular system.”
