Correct Answer is B
Explanation
A. Larynx: The larynx is located below the pharynx and above the trachea. It houses the vocal cords and plays a role in speech. In the diagram, the larynx is likely structure #6, not #4.
B. Pharynx: The pharynx is a muscular passageway for food and air. It lies behind the nasal cavity and mouth, connecting them to the larynx and esophagus. Structure #4 is positioned in that area, making it the correct answer.
C. Trachea: The trachea is the windpipe that extends from the larynx downward into the chest. It is shown lower in the diagram (likely structure #7), not #4.
D. Nose: The nose (including the nostrils and nasal cavity) is the outermost and uppermost part of the respiratory tract. In the diagram, structure #3 appears to represent the nose, not #4.
Correct Answer is ["A","C"]
Explanation
A. Increase in need for O₂: Muscles need more oxygen during exercise, so respiratory rate increases.
B. Decrease in need for O₂: This is incorrect; oxygen needs increase during exercise.
C. Increase in CO₂ levels: Exercise produces more CO₂, which stimulates breathing.
D. Increase in RBC production: This occurs over time in response to chronic hypoxia, not acutely during exercise.
E. Decrease in CO₂ levels: CO₂ levels rise during exercise, prompting faster breathing, not decrease.
