name the respiratory organs in birds and mammals:

Answer

### Step-by-Step Solution:

1. **Identify the Respiratory Organs in Birds:**
- The primary respiratory organs in birds are the **lungs**.
- Birds have a unique respiratory system that includes air sacs connected to their lungs, which aids in efficient gas exchange.

2. **Explain the Function of Bird Lungs:**
- The lungs in birds are responsible for the exchange of gases, specifically oxygen and carbon dioxide.
- The air sacs play a crucial role in the breathing process by allowing for a continuous flow of air through the lungs, ensuring that fresh air is always available for gas exchange.

3. **Identify the Respiratory Organs in Mammals:**
- In mammals, including humans, the primary respiratory organs are also the **lungs**.
- Like in birds, the lungs in mammals are structured to facilitate gas exchange.

4. **Explain the Function of Mammal Lungs:**
- In humans, the lungs contain tiny structures called **alveoli**, which are essential for the exchange of gases.
- When humans inhale, they take in oxygen, and when they exhale, they release carbon dioxide, which is a waste product of metabolism.

5. **Summarize the Answer:**
- In conclusion, the respiratory organs in both birds and mammals are the **lungs**.
