Answer
Correct Answer: (ii), (iii), (i), (iv)
Explanation
Introduction / Context:Human respiration proceeds along a well-defined anatomical route from nose to alveoli and then into circulation.
Given Data / Assumptions:
- Nostrils admit air.
- Windpipe conducts to bronchi.
- Lungs exchange gases.
- Blood carries gases to tissues.
Concept / Approach:Route: entry → conduit → exchange → transport.
Step-by-Step Solution:1) (ii) Nostrils.2) (iii) Windpipe.3) (i) Lung (alveoli).4) (iv) Blood (haemoglobin binding).
Verification / Alternative check:Breath path cannot start at lungs or blood logically.
Why Other Options Are Wrong:Any reversal of nostrils→trachea→lungs is anatomically incorrect; blood cannot precede lungs in air entry path.
Common Pitfalls:Confusing inhalation path with cellular respiration sequence.
Final Answer:(ii), (iii), (i), (iv)
