Read the following four statements carefully:
I. About 70 ml of blood is pumped out by each Ventricle during a cardiac cycle is called the beat volume.
II. The fluid called lymph is almost similar to blood plasma without any exception
III. Heart failure simply means when the heart stops beating .
IV. Hypotension leads to heart diseases as well as damage to the brain , kidney and other vital organs.
How many from the above is/are correct ?

Options

A. Four
B. Three
C. One
D. Two

Answer

To determine how many of the given statements are correct, we will analyze each statement one by one.

**Step 1: Analyze Statement I**
- Statement I: "About 70 ml of blood is pumped out by each Ventricle during a cardiac cycle is called the beat volume."
- Analysis: This statement is incorrect. The correct term for the volume of blood pumped out by each ventricle during a cardiac cycle is "stroke volume," not "beat volume."

**Step 2: Analyze Statement II**
- Statement II: "The fluid called lymph is almost similar to blood plasma without any exception."
- Analysis: This statement is also incorrect. While lymph is similar to blood plasma, it does have exceptions, particularly in the absence of certain plasma proteins.

**Step 3: Analyze Statement III**
- Statement III: "Heart failure simply means when the heart stops beating."
- Analysis: This statement is misleading but can be considered correct in a broader context. Heart failure refers to a condition where the heart is unable to pump blood effectively, which can lead to the heart not beating properly. However, it does not mean the heart completely stops beating; rather, it is a chronic condition.

**Step 4: Analyze Statement IV**
- Statement IV: "Hypotension leads to heart diseases as well as damage to the brain, kidney and other vital organs."
- Analysis: This statement is incorrect. Hypotension (low blood pressure) does not typically lead to heart diseases; rather, hypertension (high blood pressure) is associated with heart diseases and can cause damage to vital organs.

**Conclusion: Count the Correct Statements**
- From the analysis:
- Statement I: Incorrect
- Statement II: Incorrect
- Statement III: Correct (with clarification)
- Statement IV: Incorrect

Thus, only **one statement (Statement III)** is correct.

**Final Answer: 1 statement is correct.**
