bronchioles

Explanation:

Question 5

To solve this, we analyze each option:

• Pleura: Membrane around lungs, not for gas exchange.
• Alveoli: Tiny air sacs in lungs where O₂ and CO₂ exchange occurs.
• Bronchus: Airway to lungs, no gas exchange here.
• Bronchioles: Smaller airways, no gas exchange.

So the correct answer is alveoli.

Analyzing each option:

• Heimlich Maneuver: Emergency procedure to dislodge objects from trachea/throat.
• Tracheostomy: Surgical opening in trachea, not for dislodging objects.
• Endoscopy: Diagnostic/therapeutic procedure, not emergency for dislodging.
• Schick Test: Tests for diphtheria immunity, not related.

So the correct answer is Heimlich Maneuver.

Answer:

B. alveoli (assuming the options are labeled with letters, but in the given, the second option is alveoli)
