Biology Practice: Respiratory System (Mock Test 4 - Expert/Experimental Logic)
1. In a "Bell Jar" experiment representing the lungs, what does the rubber sheet at the bottom represent?
2. When the rubber sheet in the bell jar experiment is pulled down, the balloons (lungs) inflate. This is because:
3. A student exhales into a test tube containing Lime Water. The water turns milky. This proves the presence of:
4. Why does a person living at high altitudes (mountains) logically have a higher Red Blood Cell count?
5. Clinical Case: A person is suffering from "Carbon Monoxide" poisoning. Why is this gas deadly?
6. If a cell is deprived of Oxygen, it switches to anaerobic respiration. In human muscles, this creates:
7. Expert Observation: Why do we "yawn" when we are tired or bored?
8. Which instrument is used by doctors to measure the volume of air inspired and expired (Lung capacity)?
9. "Asphyxiation" is a clinical condition caused by:
10. Why is breathing through the mouth considered unhealthy compared to the nose?
11. A student notices that a mirror fogs up when they breathe on it. This proves that exhaled air contains:
12. "Bronchitis" is an expert-level term describing the inflammation of the:
13. In the case of "Pneumonia," the alveoli get filled with:
14. What is the logical reason for "Hiccups"?
15. Why is "Tidal Volume" (normal breathing) much less than "Vital Capacity"?
16. The "Residual Volume" is the air that never leaves the lungs. Its logical purpose is:
17. Emphysema is a condition (often caused by smoking) where:
18. During "Sneezing," air is expelled forcefully to:
19. If a person's pleural membrane is punctured, what is the most likely expert-logic outcome?
20. The partial pressure of Oxygen is highest in which part of the system?
