1. The Respiratory System
group of organs that take in oxygen and get rid of carbon dioxide

2. Respiration The process by which a body Gets and uses oxygen
Releases carbon dioxide and water
Two parts of the process
Breathing: inhaling and exhaling
Cellular respiration: chemical reactions that release energy from food

3. Respiratory System Organs Involved: Nose Pharynx Larynx Trachea
Bronchus
Lungs
Diaphragm

4. Pharynx
Passage from the mouth to the larynx and esophagus

5. Larynx
Area of the throat that contains the vocal cords and produces vocal sounds

6. Trachea
Tube that connects the larynx to the lungs

7. Bronchi Two tubes that connect the lungs with the trachea
*bronchus = 1 tube

8. Alveoli
Tiny air sacs of the lungs where oxygen and carbon dioxide are exchanged

9. Diaphragm
Dome shaped muscle beneath the lungs

10. Cellular Respiration
Oxygen is used by cells to release energy stored in molecules of glucose

11. Respiratory Disorders
Diseases of the lungs:
Asthma
Emphysema
Severe Acute Respiratory Syndrome (SARS)
