Question

Statement 1: The surface area of the skin that covers the entire body is less than the surface area of both the lungs.

Statement 2: The surface area of both the lungs together constitutes 70 square meters.

• A. Statement 1 is true but statement 2 is false.
• B. Statement 1 is false but statement 2 is true.
• C. Both the statements are true.
• D. Both the statements are false.

Answer 1

The correct option is C

Both the statements are true.

Lungs are the primary organs of the respiratory system in humans and many other animals. The surface area of both the lungs together constitutes 70 square meters and this is equivalent to the surface area of the tennis court. Whereas, the surface area of the skin that covers the entire body is only two square metres. Hence, both the statements are true.
