2. Vocabulary Respiration- is the entire process by which a body obtains and uses oxygen and gets rid of carbon dioxide and water. Respiratory system- the lungs heart throat and passageways that lead to the lungs Pharynx- The tube surrounding membrane and muscles that connects to the nasal passageway with the esophagus Larynx- the place where the vocal cords are located Trachea- The passageway for air traveling from the larynx to the lungs Bronchi- One bronchus goes to each lung and branches into thousands of tiny tubes called bronchioles Alveoli- thousands of tiny sacs in of the lungs Lung-A saclike organ that takes oxygen from air and delivers in to the blood. Cellular respiration- oxygen is used to release energy stored in molecules of carbohydrates fats and proteins.

3. Larynx Larynx is a voice box, contains the vocal cords. The vocal cords are a pair of rubber bands that are stretched across the opening of the larynx. Muscles that are attached to the larynx control how much the vocal cords are stretched. When the air flows between the vocal cords, they vibrate and make a sound. The larynx guards the opening of the trachea.

4. Pharynx Through the nose air flows into the pharynx(also known as the throat). You can use a mirror to see the walls of your pharynx. In addition to air food and drink also travel through the pharynx in the way to the stomach. The pharynx branches into two tubes. One leads to the stomach and is called the esophagus. The other leads to the lungs and is called the larynx. Through the nose air flows into the pharynx(also known as the throat). You can use a mirror to see the walls of your pharynx.

5. Bronchi The trachea splits into two tubes called bronchi. One bronchus goes to each lung and branches into thousands of tiny tubes called bronchioles. A large air-tube of the tetra pod lung. Each lung has one large bronchus, connecting it to the trachea. Within the lung the bronchus branches successively into five lobar bronchi. The trachea splits into two tubes called bronchi. One bronchus goes to each lung and branches into thousands of tiny tubes called bronchioles. A large air-tube of the tetra pod lung. Each lung has one large bronchus, connecting it to the trachea. Within the lung the bronchus branches successively into five lobar bronchi.

6. Trachea The larynx guards the entrance of the large tube called the trachea (also known as the windpipe). The trachea is the passageway for air traveling from the larynx to the lungs. Commonly called the windpipe, the main airway to the lungs; it lies between the larynx and the main bronchi.

Commonly called the windpipe, the main airway to the lungs; it lies between the larynx and the main bronchi.

7. Alveoli Your body has two large sponge like lungs. In the lungs, each bronchiole branches to form thousands of tiny air sacs called alveoli (singular, alveolus). Capillaries surround each alveolus. The alveoli is located in the lungs.

8. Lungs There are two, the left is slightly smaller than the right. Bronchioles branch and form thousand of alveoli. Lung cancer is the most common cancer in North America. Oxygen and carbon dioxide are exchanged in the lung. There are two, the left is slightly smaller than the right. Bronchioles branch and form thousand of alveoli.

9. What happens to the oxygen? Carbon dioxide enters the air in the alveolus, oxygen is picked up by blood. Tissues and cells pick up oxygen from the blood, carbon dioxide from the blood, carbon dioxide enters the blood Carbon dioxide enters the air in the alveolus, oxygen is picked up by blood. Tissues and cells pick up oxygen from the blood, carbon dioxide from the blood, carbon dioxide enters the blood

10. Cellular Respiration Oxygen is used to release energy stored in molecules of carbohydrates. When that happens energy is released along with carbon dioxide and water they leave the cell and return to the blood stream. Oxygen is used to release energy stored in molecules of carbohydrates.

11. Breathing Air is sucked in or forced out of the lungs. The diaphragm ( a muscle underneath the lungs) controls breathing. When the diaphragm moves the rib cage lifts causes it to expand and then air is sucked in. Air is sucked in or forced out of the lungs.

12. Respiratory Disorders Though the respiratory system works very well there are things that can go wrong. Asthma Pneumonia Smoking can cause unhealthy lungs Though the respiratory system works very well there are things that can go wrong. Asthma Pneumonia Smoking can cause unhealthy lungs
