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 do the small hairs and mucus do to the air when you breathe in through your nose?






2. What does the respiratory system include?






3. What is the job that the respiratory system does for the body?








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. Why is breathing in through the nose better than breathing in through the mouth?






2. As you breathe out what happens?






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








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. Explain the process of what happens when you breathe air in.








2. Explain the process of what happens when you breathe air out.
