Gaseous exchange through the skin is known as ______________ respiration?
Correct answer: B. Cutaneous
- A. Cuticular
- B. Cutaneous
- C. Skin
- D. Pulmonary
Explanation
Gaseous exchange through the skin is called cutaneous respiration. Oxygen diffuses through the moist skin into blood and carbon dioxide diffuses out, as seen prominently in earthworms and amphibians. Cuticular respiration is a tempting choice because it refers to exchange through a cuticle, not the skin itself.
