NEET Zoology Heart & Circulation Match the Following Question
Type: Match the Following-match the column-Medium-Class 11
Match Column-I with Column-II.
Column-I Column-II (a) Sino-atrial node (i) Depolarisation of atria (b) QRS complex (ii) O2 exchange in lungs (c) Pulmonary circulation (iii) Contraction of ventricles (d) T-wave (iv) Return to left atrium
Choose the correct matching:
A
a-i, b-iii, c-ii, d-iv
B
a-ii, b-iii, c-iv, d-i
C
a-iii, b-i, c-iv, d-ii
D
a-i, b-ii, c-iv, d-iii
Correct Answer
Option A
Detailed Explanation
The sino-atrial node initiates the electrical activity that leads to the depolarisation of the atria (P-wave), the QRS complex represents ventricular depolarisation, the pulmonary circulation involves the return of oxygenated blood to the left atrium, and the T-wave represents the repolarisation of the ventricles.
