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

Level#1: Inhaled air moves into your throat. Both air and food pass down the throat. Food continues through it to another tube that leads to the stomach. Next, air moves into the trachea. The trachea, or windpipe, brings air from your throat into your lungs. When you swallow a flap of tissue, called the epiglottis, closes. It keeps food and liquids out of the trachea.

1. Where does the air, you breathe in, go after it leaves the throat?






2. What is the job of the trachea?





3. What is the job of the epiglottis?









Level#2: Inhaled air moves into your throat. Both air and food pass down the throat. Food continues through it to another tube that leads to the stomach. Next, air moves into the trachea. The trachea, or windpipe, brings air from your throat into your lungs. When you swallow a flap of tissue, called the epiglottis, closes. It keeps food and liquids out of the trachea. The trachea divides into two smaller tubes. These smaller tubes are called bronchi. Each of these tubes (bronchus) goes into a lung. Air moves through these small tubes and into your lungs. You have two lungs. They are big, spongy organs. In each lung, the bronchus branches into smaller and smaller tubes. These tubes end in millions of tiny air sacs. These air sacs are called alveoli.

1. Where does the air go after it leaves the throat?





2. What does the trachea do?





3. What is the epiglottis and why is it important?

You have two lungs. They are big, spongy organs. In each lung, the bronchus branches into smaller and smaller tubes. These tubes end in millions of tiny air sacs. These air sacs are called alveoli. In these sacs, gases are exchanged. Oxygen passes into capillaries. The waste gas carbon dioxide passes from the blood into the air sacs. You get rid of carbon dioxide when you breathe out, or exhale.

1. Explain the process that gets air into the lungs.






2. What is the epiglottis and what does it do?






3. What does the trachea divide into, what are they called, and where do they go?
