A	Alveoli	I	Gas Exchange
B	Bronchioles	III	Regulate air flow & distribution
C	Diaphragm	IV	Muscle helps to expand & contract lungs
D	Trachea	II	Passage for air to enter & leave the lungs

• A. (A)-(I), (B) - (IV), (C) - (III), (D) - (II)
• B. (A) - (I), (B) - (III), (C) - (II), (D) - (IV)

• D. (A) - (I), (B) - (III), (C) - (IV), (D) - (II)

Hint:

Understanding the specific functions of each component of the respiratory system enhances comprehension of respiratory physiology.

Answer 1

The Correct Option is C

The correct matches are listed below:

• Alveoli (A): facilitate gas exchange (I)
• Bronchioles (B): control air flow and its distribution (III
• Diaphragm (C): is the muscle responsible for lung expansion and contraction (IV)
• Trachea (D): functions as the primary airway for lung entry and exit (II)
