NEET Zoology Respiratory Organs Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Inspiration | (i) Increase in intra-pulmonary pressure |
| (b) Expiration | (ii) Diaphragm contraction |
| (c) Thoracic volume | (iii) Air moves into lungs |
| (d) Pulmonary volume | (iv) Decrease in thoracic volume |
a-iii, b-i, c-ii, d-iv
a-ii, b-iv, c-iii, d-i
a-iv, b-iii, c-i, d-ii
a-i, b-ii, c-iv, d-iii
Correct Answer
Detailed Explanation
Inspiration involves the contraction of the diaphragm, leading to an increase in thoracic volume, which decreases intra-pulmonary pressure and allows air to flow into the lungs. Expiration is the opposite process, where relaxation of the diaphragm reduces thoracic volume, increasing intra-pulmonary pressure and expelling air from the lungs.
