Name the region of lungs where exchange of gases occurs.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the specific region of the lungs where the exchange of gases occurs.

2. **Identifying the Process**: The process of gas exchange is a part of respiration, which is essential for supplying oxygen to the body and removing carbon dioxide.

3. **Recognizing the Key Organ**: The lungs are the primary organ involved in respiration and gas exchange.

4. **Locating the Specific Region**: Within the lungs, the specific structures where gas exchange occurs are called **alveoli**.

5. **Explaining the Function of Alveoli**: Alveoli are tiny air sacs in the lungs where oxygen from the air is transferred to the blood, and carbon dioxide from the blood is expelled into the lungs to be exhaled.

6. **Mentioning Associated Structures**: Along with alveoli, there are tiny blood vessels called **capillaries** that surround the alveoli and facilitate the exchange of gases.

7. **Final Answer**: Therefore, the region of the lungs where gas exchange occurs is the **alveoli**, along with the associated **capillaries**.
