Answer»

option C is CORRECT

Explanation:

The correct sequence of EVENTS in the initiation of RESPIRATION is:

(i) The contraction of external intercostal muscles raises the ribs and sternum

(ii) The volume of thorax increases in the dorsoventral axis

(iv) Diaphragm contraction

(vi) The volume of thorax increases in the anterior-posterior axis

(iii) Intrapulmonary pressure decreases

(v) Air RUSHES into lungs

So, the correct answer is '(i),(ii),(iv),(vi),(iii),(v)'.
