W |
When humans exercise, more oxygen is required for respiration and more carbon dioxide needs to be expelled. |
|
What change to the amount of different gases needed and expelled when exercising? |
|
|
W |
When humans exercise heart (pulse) rate increases to supply more blood to the lungs. |
|
What changes with the heart when oxygen is needed more quickly? |
|
|
W |
When humans exercise we breath faster and deeper to supply more air to the lungs. |
|
What changes with the breathing when oxygen is needed more quickly? |
|
|
T |
Asthma is caused by inflammation (swelling) of the breathing tubes that carry air in and out of the lungs. |
|
What does asthma do to the breathing tubes? |
|
|
W |
This inflammation makes the breathing tubes narrower and so restricts speed at which air can enter the lungs. |
|
How does asthma affect breathing? |
|
|
T |
Tobacco smoke contains:
- Tar
- Nicotine
- Carbon monoxide |
|
Name the three main chemicals in tobacco smoke that can reduce the oxygen pumped around the body? Use the fact sheets to create a matrix map to show short and long term effects of smoking |
|
|
T |
The tar lines the surface of the lungs. |
|
What does tar do to the lungs? |
|
|
W |
The tar adds a barrier which slows down diffusion. |
|
How does tar affect how well the body can get oxygen? |
|
|
T |
Carbon monoxide is more reactive than oxygen. |
|
How is the reactivity of carbon monoxide compared to oxygen? |
|
|
W |
Carbon monoxide takes the place of oxygen on the red blood cells, leaving less oxygen to be transported to the cells. |
|
How does carbon monoxide affect how well the body can get oxygen? |
|
|
T |
Nicotine is addictive - it causes a smoker to want more cigarettes. Nicotine also increases the heart rate and blood pressure, and makes blood vessels narrower than normal. This can lead to heart disease. |
|
How does nicotine affect how well the body can get oxygen? |
