NEET Zoology Heart & Circulation Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Stroke Volume (i) Electrical excitation of the ventricles (b) Cardiac Output (ii) Amount of blood pumped per heartbeat (c) Sino-atrial Node (iii) Specialised tissue generating impulses (d) QRS Complex (iv) Product of heart rate and stroke volume
Choose the correct matching:
a-ii, b-iv, c-iii, d-i
a-iv, b-ii, c-i, d-iii
a-ii, b-iii, c-i, d-iv
a-i, b-iv, c-ii, d-iii
Correct Answer
Detailed Explanation
Stroke volume is defined as the amount of blood pumped by each ventricle per heartbeat, while cardiac output is indeed the product of stroke volume and heart rate. The sino-atrial node is a specialized tissue responsible for generating impulses, and the QRS complex corresponds to the electrical excitation of the ventricles.
