Choose the correct option:
- A i, ii and iii only
- B ii, iii and iv only
- C iii, iv and v only
- D i, iv and v only
Answer & Solution
Correct Answer
(B) ii, iii and iv only
Step-by-step Solution
Detailed explanation
During inspiration when the lungs expand to a critical point, the stretch receptors are stimulated and impulses are sent along the vagus nerves to the expiratory centre.
It prevents the lungs from inflating to the point of bursting.
It prevents the lungs from inflating to the point of bursting.
