|
Nose (nasal cavity)
|
Warms, filter air as it enters the body.
|
|
|
Larynx (voice box)
|
Upper part of the trachea;contains vocal cords,2 bands of tissue stretched across opening of vibrates.
|
|
|
Trachea
|
Air passage way covered with epiglottis. catches impurities found in the air.
|
|
|
???
|
Exchange and transport of gases carbon dioxide (co2) leaves cells;
oxygen (o2) enters. |
|
|
Bronchi
|
Tubes that carry air from trachea to lungs.
|
|
|
Bronchioles
|
Smaller tubes that branch from bronchi
|
|
|
Alveoli
|
Grape-like air sac clusters surrounded by network of thin walled capillaries at the end of bronchioles
|
|
|
Lungs
|
Sac-like organs ; site of gas exchange between air and blood.
|
|
|
When the body does work...
|
1. co2 is made in our cells
2. co2 moves into the blood stream , co2 in the blood forms carbonic acid. 3. Receptors in the blood vessel measure acid level. 4. If acid level rises , receptors send message to the brain for the heart to beat faster and lungs to breathe faster (inhale more O2 is exhaled more co2. 5. As more co2 is exhaled , there is less co2 in the blood. 6. Receptors send a message to the brain for the heart and lungs to turn back to normal. |
|
|
What caused the bromothymol blue solution to change color? Is this a physical or chemical change.
|
Bromothymol blue solution changed colors because, it is a carbonic acid that is why it's a chemical change.
|
|
|
Explain why there is a difference between the resting pulse and respiration rates and the exercise pulse and respiration rates.
|
The difference between the resting pulse is how many times your heart beats. respiration rate is how many times you breathe.
|
|
|
What was the purpose of the third beaker?
|
Control group
|
|
|
Why would this be helpful?
|
To show what it looked like before the acid.
|
|
|
How did you collect data: quantitatively, qualitatively,or both
|
you measure quantitatively data because of the numbers.
You can't measure qualitatively because of its looks. |
|
|
How does exercise related to the amount of carbon dioxide exhaled?
|
Exercise relate to the amount of carbon dioxide exhaled because you are breathing faster than usual.
|
|
|
If you were in good physical shape, how would that affect the results of this activity?Relate your answer to the efficiency of the systems.
|
It would affect the results because you don't have to breathe as much.
|
|
|
Explain the relationship between the structure of the respiratory and circulatory system function together?
|
Your structure of the respiratory system is where your air passes through,and circulatory system is where every thing is transfer around your body.
|
|
|
Carbon dioxide moves...
|
Into the blood stream (forms carbonic acid).
|
|
|
The receptors send a message to the brain to...
|
Brings everything to normal.
|
|
|
A message from the receptors to the brain causes...
|
Heart to beat faster and the lungs to breathe faster.
|
|
|
Pulmonary (Lung) obstructive disorders represent what?
|
Pulmonary (lung) obstructive disorders represent the flow of air impeded while restrictive orders is the volume of air reduced.
|
|
|
Emphysema is ...
|
walls between the air sacs of b(alveoli) lose elasticity.
Without elasticity, air sacs would become trapped in the air sacs. |
|
|
Chronic Bronchitis
|
Airways are inflammable and thickened,and an increase in the number and size of mucus-producing cells occurs.
|
|
|
Chronic Obstructive Pulmonary Disease (COPD)
|
Consisting of emphysema and chronic bronchitis.
|
|
|
Asthma
|
Inflamed,swollen airways.When airways react, they get narrower, so less air flows to the lungs.
|
|
|
Lung Cancer
|
Is abnormal, uncontrolled cell growth in the lungs.
|
|
|
Cystic Fibrosis
|
Inherited disease of mucus and sweat glands.
|
|
|
Abnormal gene
|
cause mucus to become so sticky and thick builds up in the airways, causing blockage,bacterial growth, and repeated lung infections.
|
|
|
Peak expiatory flow (PEF)
|
Measure of how quickly a person exhaled air.
|
