1. Both statements are correct
2. only statement I is correct
3. only statement II is correct
4. neither statement is correct

Inhaled air contains more CO2 than exhaled air

1. true
2. false

produced in respiration

needed for respiration

energy

H2O= water

glucose

CO2 carbon dioxide

O2= oxygen

Biological concepts

nasal lining: neusslijmvlies

mucosa: slijm

uvula: huig

epiglottis: strotklepje

vocal chords: stembanden

Where in your body do you find the vocal chords?

1. bronchi
2. windpipe
3. pharynx
4. larynx

When food is entering our body it goes via direction:

1. 1
2. 2
3. 3
4. 4

worksheet breathing in animals

One of the erlenmeyer flasks will indicate CO2 moest quickly. In which of the erlenmeyer flasks will increase the CO2 level the most? In P or Q, and why?

Question

Two groups of muscles involved in breathing are the abdominal muscles and the diaphragm muscles. Does air flow into the trachea through the cannula due to the contraction of these muscles?

Due to contraction of

1. abdominal muscles
2. diaphragm muscles
