When `CO_(2)` concentration in blood increases breathing becomes

A

shallower and slow

B

there is no effect on breathing

C

slow and deep

D

faster and deeper

Text Solution

Verified by Experts

The correct Answer is:
D
When `CO_(2)` concentration in blood increases breathing becomes faster and deeper.The effect of increased `CO_(2)` is to decrease the affinityu of haemoglobin for `O_(2)`
Thus due to Bohr's effect the `CO_(2)` released in respiring tissue accelerates the delivery of oxygen by faster and deeper breathing.
