<td valign="top"><strong>The verb that means ) |
inhale |
| #3 | The verb that means 'to breathe out' | exhale |
| #4 | When we inhale our diaphragm moves in which direction? | down |
| #5 | 5th graders breathe on average about how may times per minute? | 20 |
| Gas Exchange | ||
| #1 | These carry oxygen  |
red blood cells |
| #2 | What type of blood vessel surrounds the alveoli? | capillary |
| #3 | The exchange of gases in the lungs happen here. | in the alveoli |
| #4 | A strong attraction or force between particles that causes them to combine. | affinity |
| #5 | A gas we inhale that every cell in the body needs. | oxygen |
| Respiratory Diseases | ||
| #1 | common respiratory illness that causes a person to wheeze. | asthma |
| #2 | This is an infection of the lungs that causes your body to make extra mucus and/or pus that can get trapped in the aveloli. People with this disease often have fever, chills and a bad cough. | pneumonia |
| #3 | serious lung disease often caused by smoking that make it difficult fo the alveoli to take in oxygen. | emphysema |
| #4 | great for building strong muscles and important in the prevention of respiratory illness | exercise |
| #5 | pollen, dust and pets are common triggers of this respiratory illness | allergies |
| Smoking | ||
| #1 | A system of the body besides the respiratory system that is badly damaged by smoking:  |
circulatory system |
| #2 | Smokers often have more respiratory illnesses then non-smokers. One of the reasons for this is because smoke destroys these tiny hairs that push dust and dirt out of the air passages.. | cilia |
| #3 | This is the sticky substance in cigarettes that coat the bronchi and make it harder for oxygen to pass to the alveoli | tar |
| #4 | a disease in which a tumor forms in the lungs; smoking often causes it | lung cancer |
| #5 | the addictive chemical in tobacco | nicotine |
| Final Question | |
| This gas is produced by smoking and has a much greater affinity (200 to 300 times greater) to the red blood cells then oxygen. | carbon monoxide |
