Questions and Answers

Which primary function of the integumentary system directly prevents dehydration?

  • Excretion of waste through sweat
  • Prevention of water loss (correct)
  • Regulation of body temperature
  • Protection against foreign particle entry

How does the integumentary system facilitate interaction with the external environment?

  • By preventing entry of foreign particles
