If the trachea is blocked, which life process will be affected immediately?
Answer and explanation
Correct answer: Respiration
The governing concept is the role of the respiratory passage in ventilation. The trachea, or windpipe, conducts air from the throat toward the bronchi and lungs. A blockage reduces or stops airflow, so oxygen cannot reach the gas-exchange surfaces normally and carbon dioxide removal is impaired. Therefore option A is correct. Photosynthesis occurs in plant cells, while urine formation and food absorption involve the kidneys and intestine.
