The correct Answer is:
To determine whether the given statement is true or false, we need to analyze the statement carefully. ### Step 1: Understand the Statement The statement claims that the actual site of diffusion of oxygen (O₂) and carbon dioxide (CO₂) between blood and atmospheric air is the "exchange part." ### Step 2: Identify the Exchange Part In the context of human respiration, the "exchange part" refers to the alveoli in the lungs. The alveoli are tiny air sacs where the exchange of gases occurs. ### Step 3: Explain the Process of Gas Exchange In the alveoli, oxygen from the inhaled air diffuses into the blood, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. This process is crucial for maintaining the oxygen and carbon dioxide levels in the body. ### Step 4: Conclusion Since the alveoli are indeed the site where the diffusion of O₂ and CO₂ occurs between blood and atmospheric air, the statement is true. ### Final Answer **The statement is true.** ---
