Test 2

Question 1

Regulators of respiration

Answer 1

Cerebral cortex( in charge of the skeletal muscle)

Inflation reflex

Chemical stimuli

Question 2

Cerebral cortex in breathing

Answer 2

In charged of the skeletal muscle, helps control the breathing
They have voluntary control
But they have a limited if there is too much CO2. It will override the control

Question 3

Inflation reflex

Answer 3

It’s a stretch receptor found in the walls of bronchi and bronchioles.
The walls of the lungs can then only stretch to a certain point
This is what prevents from over inflation of the lungs

Question 4

Chemical stimuli

Answer 4

They determine ph
Chemoreceptors are found in carotid and aortic sinuses
They are sensitive to CO2 and ph

Question 5

What happens when the co2 increases

Answer 5

CO2 increases
PH decrease
Stimulates the inspiration center
Hyperventilation (heavy breathing)
