BIOXI17: BREATHING AND EXCHANGE OF GASES

338774 Spontaneous respiration ceases after transection of the

1 Brainstem above the pons

2 Spinal cord below the diaphragm

3 Brainstem at the inferior end of the medulla

4 Spinal cord above the conus medullaris

BIOXI17: BREATHING AND EXCHANGE OF GASES

338775 Increase in ${CO}_{2}$ concentration shall cause

1 Slower and shallower breathing

2 Faster and deeper breathing

3 Slower and deeper breathing

4 No effect on breathing

Explanation:

Increase in ${CO}_{2}$ concentration shall cause faster and deeper breathing.
