Practice questions testing deep understanding of breathing mechanisms, respiratory volumes, and high-altitude adaptations.
Syllabus History & Status (Respiratory System):
Q1. A mountaineer climbs Mount Everest without supplementary oxygen. As they reach higher altitudes, they find themselves breathing extremely rapidly and experiencing a racing heartbeat. Explain the physiological reasons for these changes, and describe the long-term adaptations their body would undergo if they stayed at high altitude for several weeks.
Q2. Assertion (A): Carbon monoxide (CO) inhalation is highly toxic and can lead to rapid asphyxiation and death. Reason (R): Carbon monoxide has an affinity for hemoglobin that is over 200 times higher than that of oxygen, forming a stable compound called carboxyhemoglobin which prevents oxygen transport.
