Given below are four statements ( A-D ) each with two blanks. Select the option which correctly fills up the blanks in two statements.
I.1100-1200
II. 1/5th

Options

A. During a cardiac cycle each Ventricle pumps out approximately .......i......of blood which is called as the ....ii...
B. The first heart sound (lub) is associated with the closure of the …..i….... values whereas , the second heart sound (dud) is associated with the closure of the …...ii…... Valves .
C. On an average …….i…….ml of blood is filtered by the kidneys per minute which constitute roughly ……….ii………of the blood pumped out by each ventricle of the heart in a minute .
D. A comparison of the volume of the filtrate formed per day …….i……litres with that of the urine released suggests that nearly ……..ii…….of the filtrate has to be reabsorbed by the renal tubules .

Answer

To solve the question, we need to fill in the blanks in the statements provided with the correct answers: "1100-1200" and "1/5th". Let's analyze the statements step by step.

### Step-by-Step Solution:

1. **Understanding the First Statement**:
- The statement mentions that in every cardiac cycle, each ventricle pumps out a certain volume of blood. We know from physiology that the volume pumped out by each ventricle per heartbeat is called the "stroke volume," which is approximately 70 ml.
- However, the question indicates that we need to fill in the blanks with "1100-1200". This suggests that the statement might be referring to the total volume of blood filtered by the kidneys per minute, which is indeed around 1100-1200 ml.

2. **Analyzing the Second Statement**:
- The second part of the statement mentions a fraction of blood that is pumped out from one ventricle. We know that the kidneys filter about 20% of the blood that is pumped out by the heart. This fraction can be expressed as "1/5th".
- Therefore, this statement can be filled with "1/5th" in the second blank.

3. **Combining the Findings**:
- Based on our analysis, the first blank can be filled with "1100-1200" (referring to the volume of blood filtered by the kidneys), and the second blank can be filled with "1/5th" (referring to the fraction of blood pumped out from one ventricle that the kidneys filter).

4. **Finalizing the Correct Option**:
- After analyzing the statements and filling in the blanks, we find that the correct option that fits both blanks is option C, which states that an average of "1100-1200 ml" blood is filtered by our kidneys per minute, which is "1/5th" of the blood pumped out from the ventricle.

### Conclusion:
The correct answer is option C, where the blanks are filled with "1100-1200" and "1/5th".
