Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: The Respiratory System

Level#1: The respiratory system moves oxygen into the body and carbon dioxide out of the body. This system includes the lungs and the pathways that air move through. The air your breathe contains oxygen. It can go into your nose. The small hairs and mucus in your nose filter out dust and dirt.

1. What does the respiratory system do for the body?





2. What does the air you breathe contain?





3. Where can the air go and what happens when it goes there?

Level#2: The respiratory system moves oxygen into the body and carbon dioxide out of the body. This system includes the lungs and the pathways that air move through. The air your breathe contains oxygen. It can go into your nose. The small hairs and mucus in your nose filter out dust and dirt. You can breathe in air through your mouth. But, your mouth cannot clean the air as well as your nose can. As you breathe out, air rushes past your vocal cords. This action, along with the movement of the tongue and mouth, allows you to speak, sing, and make others noises as a result. 

1. What body system moves oxygen into the body and carbon dioxide out of the body?

Level#3: The respiratory system moves oxygen into the body and carbon dioxide out of the body. This system includes the lungs and the pathways that air move through. The air your breathe contains oxygen. It can go into your nose. The small hairs and mucus in your nose filter out dust and dirt. You can breathe in air through your mouth. But, your mouth cannot clean the air as well as your nose can. As you breathe out, air rushes past your vocal cords. This action, along with the movement of the tongue and mouth, allows you to speak, sing, and make others noises as a result. As you breathe in, the muscles in your chest lift your rib cage up and outward. At the same time, a large skeletal muscle, called the diaphragm, pulls the bottom part of your chest cavity downward. Both actions increase the amount of space in your chest cavity so that air can move into your lungs. When you breathe out, the rib muscles and diaphragm relax. The size of your chest gets smaller, and air is forced out.

1. What is the function of the respiratory system and what parts does it include?

2. What does the air you breathe contain and what happens to it when you breathe in through your nose?

3. What does the action of breathing out, along with the movement of the mouth and tongue, allow us to do?
