6. Inhalation
- A. Expiration
- B. Respiration
- C. Aspiration
- D. Aspiration
Correct answer: B
Rationale: The correct answer is B: 'Respiration.' Inhalation refers to the process of breathing in air, while respiration is the overall process of gas exchange in the body, including both inhalation and exhalation. Expiration refers specifically to the process of breathing out air. Aspiration, on the other hand, refers to the act of inhaling foreign objects into the lungs, which can be harmful. Therefore, 'Respiration' is the most appropriate term related to 'Inhalation' as it encompasses the entire process of breathing and gas exchange in the body.
