Answer
Correct Answer: B, C, A, D
Explanation
Introduction / Context:Trace the path of inhaled air to oxygen transfer into blood.
Given Data / Assumptions:Nostrils → Windpipe (trachea) → Lung → Blood (via alveoli).
Concept / Approach:Follow anatomical route of air and diffusion.
Step-by-Step Solution:Nostrils (B) admit air.Windpipe (C) conducts air to lungs.Lung (A) houses alveoli.Blood (D) receives O2 across alveolar membranes.
Verification / Alternative check:Basic physiology confirms this pathway.
Why Other Options Are Wrong:They misorder anatomical structures or start with blood.
Common Pitfalls:Confusing trachea with esophagus.
Final Answer:B, C, A, D
