Transcript
The Respiratory System
1. Air leaves the trachea and passes through the:
bronchioles
bronchi
capillaries
2. The tiny sacs in the lungs are called:
bronchioles
capillaries
alveoli
3. In the alveoli carbon dioxide:
passes out of the blood
passes into blood
passes away from the air
4. When we exhale, pressure in the chest:
reduces
remains the same
increases
5. Respiration is the release of energy from glucose in the:
lungs
blood
muscles
6. During exercise working muscles need more:
carbon dioxide
water
oxygen
7. Insufficient oxygen supplies are available during:
strenuous exercise
warm up
normal exercise
8. During anaerobic exercise there is a build up of:
oxygen
water
lactic acid
9. Gaseous exchange takes place in the lungs in the:
bronchioles
bronchi
alveoli
10. The percentage of oxygen in exhaled air is about:
26%
36%
16%
11 – Complete the following statement using the word bank below.
MUSCLES
ALVEOLI
o2
BLOOD
Co2
Gaseous Exchange:
As ___________ passes through the ___________ in the lungs it ‘deposits’ the
waste products (_______ and nitrogen) which it has picked up around the body.
It then ‘picks up’ the ________ which has been breathed in and transports it to
the working _____________ around the body.
12. Aerobic Respiration:
__________ + glucose = Energy + Water + ______________
13. Anaerobic Respiration:
Glucose = Energy + __________________
14.
Describe what happens to the diaphragm when you breathe in (inspiration) and
when you breathe out (expiration). (2 marks)
