Explanation:

To solve this matching problem, we analyze each word and its corresponding clue based on knowledge of the respiratory system:

• Oxygen: A gas absorbed into the bloodstream (I).
• Epiglottis: A flap of tissue covering the larynx (G).
• Bronchi: Main passageways to the lung (D).
• Carbon dioxide: A gas exhaled by the lungs (F).
• Alveoli: Tiny air sacs in the lungs (L).
• Larynx: Where the vocal cords are located (A).
• Lungs: A pair of organs protected by the ribcage (E).
• Diaphragm: A large muscle that allows breathing (B).
• Trachea: The windpipe (J).
