Respiration System Flashcards
0
Q
Concentration gradient adaptions
A
Blood has little oxygen when it gets to alveoli
Lots of CO2
Concentration of O2 is higher
1
Q
Surface area adaptions
A
Lots of alveoli increase SA
large SA = fast diffusion
More area to absorb gases
2
Q
Diffusion distance adaptations
A
V short %
Only 1 cell thick wall
3
Q
Moisture adaptations
A
Aids diffusion so gases dissolve and move across wall
4
Q
What is a waste product of respiration
A
CO2
More is breathed out that in
5
Q
What is the temp of air breathed out
A
37
6
Q
Why is more H2O breathe out than in
A
The moisture in the lungs evaporates
7
Q
What are the effects of exercise on breathing
A
Increase in ventilation rate
Increase in tidal volume
8
Q
Effects of smoking
A
Heart attack Stroke Lung cancer Emphysema Yellow teeth Staines fingers Gum disease Tooth loss
