Question

Match List - I with List - II.

List - I                       List - II
A. End Diastolic volume     I. The amount of blood remaining in each ventricle at the end of ventricular systole
B. End-systolic volume     II. The percentage of the EDV represented by the SV
C. Stroke volume            III. The amount of blood in each ventricle at the end of ventricular diastole
D. Ejection Fraction       IV. The amount of blood pumped out of each ventricle during a single beat

Choose the correct answer from the options given below :

• A. A-I, B-II, C-III, D-IV
• B. A-IV, B-III, C-II, D-I
• C. A-III, B-I, C-IV, D-II
• D. A-II, B-IV, C-I, D-III

Hint:

Stroke volume measures blood pumped per beat, while ejection fraction indicates the efficiency of ventricular pumping.

Answer 1

The Correct Option is C

Concept: These terms are important measurements related to cardiac function and blood circulation.
• End Diastolic Volume (EDV) -- volume of blood in the ventricle after filling during diastole.
• End-Systolic Volume (ESV) -- blood remaining in the ventricle after contraction.
• Stroke Volume (SV) -- amount of blood pumped out in one heartbeat.
• Ejection Fraction (EF) -- percentage of EDV pumped out during systole.

Step 1: Match each term with its definition.
\[ \begin{aligned} \text{End Diastolic Volume} &\rightarrow \text{Amount of blood in ventricle at end of diastole} \text{End-systolic Volume} &\rightarrow \text{Blood remaining after ventricular systole} \text{Stroke Volume} &\rightarrow \text{Blood pumped out during one beat} \text{Ejection Fraction} &\rightarrow \text{Percentage of EDV represented by SV} \end{aligned} \]

Step 2: Write the correct matching sequence.
Thus, the correct matching is: \[ A-III,\ B-I,\ C-IV,\ D-II \] Hence, the correct answer is: \[ \boxed{(C)\ A\text{-}III,\ B\text{-}I,\ C\text{-}IV,\ D\text{-}II} \]
