1. What best describes choking?
2. What best describes bronchitis?
3. What best describes why we yawn (Check out this video)?
4. What is the best description of how mouth to mouth helps a person?
5. Why do some people sneeze when they see bright light after being in darkness?
6. Cigarette smoking is a main cause of emphysema, what is emphysema?
1. What best describes choking?
- When an object gets stuck in your esophagus
- When an object gets stuck in your trachea
- When air gets stuck in your trachea
- When air gets stuck in your esophagus
2. What best describes bronchitis?
- Inflammation of the lining of your trachea
- Inflammation of the lining of your bronchial tubes
- inflammation of the lining of your alveoli
- inflammation of the lining of your bronchiti
3. What best describes why we yawn (Check out this video)?
- Our body is trying to get a sudden intake of oxygen to provide more energy
- Our body is trying to quickly expel an excess of carbon dioxide
- Our body is trying to stretch out the skeletal muscles and increase blood flow
- Our body is trying to cool the brain down
4. What is the best description of how mouth to mouth helps a person?
- It helps the muscles in the lungs continue to work even when passed out
- When we exhale we still have a sufficient amount of oxygen to help the person take in oxygen
- It helps to keep the blood circulating around the body
- It allows you to take out the excess carbon dioxide by breathing it out for them
5. Why do some people sneeze when they see bright light after being in darkness?
- The nerve that detects bright lights runs very close to the nerve that detects irritation in the nose so the light nerve accidentally triggers the sneeze nerve
- Light irritates the cilia in someone's nose, and they mistake light for a foreign object
- The sudden light causes your capillaries in your nose to expand quickly, which irritates your nose and makes you sneeze
- The wavelengths of sunlights are the same size as microscopic particles in the environments and your nose confuses the two
6. Cigarette smoking is a main cause of emphysema, what is emphysema?
- When your trachea becomes so irritated that it creates excess scar tissue and decreases the size of the airway
- When the bronchi tubes get irritated by the tar in smoke and you create mucus which clogs your lungs
- When your alveoli become damaged or destroyed and can no longer exchange oxygen as well as they should
- When the nasal cavity gets damaged and can no longer filter unhealthy air
