The lungs are _____ to the skin.

The lungs are _____ to the skin.

• A. Superficial
• B. Internal
• C. Deep
• D. External

Answer: (C)

Think in terms of distance from the body surface. The skin is the outermost boundary, so anything beneath it is not near the surface. The lungs sit inside the chest cavity, protected by the rib cage, far from the skin’s surface. That makes them deep to the skin. The term superficial would mean near the surface, which isn’t true here, and external would mean outside the body, which isn’t the case. Internal is true in a general sense, since the lungs are inside the body, but deep best describes their position relative to the skin.
