#### 2. Complete the text about the process of respiration.

The process of respiration involves the movement of air into and out of the body, as well as the exchange of oxygen and carbon dioxide. Using the provided words, we can fill in the blanks as follows:

Text:
First, air enters through our NOSE and MOUTH.
The air goes down through the TRACHEA and the BRONCHI.
The OXYGEN enters in the LUNGS.
OXYGEN (O2) passes into the BLOOD.
CARBON DIOXIDE (CO2) leaves our body when we BREATHE OUT.

#### 3. True or False?

Now, let's evaluate each statement:

1. The respiratory system is made up of oxygen, nose, nostrils, and lungs.
- False: The respiratory system includes organs such as the nose, mouth, trachea, bronchi, lungs, and diaphragm. Oxygen is not a part of the respiratory system; it is a gas that the system processes.

2. The respiratory system takes oxygen (O2) and releases carbon dioxide (CO2).
- True: The primary function of the respiratory system is to take in oxygen and release carbon dioxide.

3. The oxygen passes into the blood.
- True: Oxygen from the lungs diffuses into the bloodstream during gas exchange.

4. Air enters our body through our lungs.
- False: Air enters the body through the nose and mouth, not directly through the lungs.

5. The air goes down through the lungs to the bronchi.
- False: Air travels from the nose/mouth through the trachea and then into the bronchi, which lead to the lungs.
