Mark the wrong statement

Options

A. In man left kidney is below the right
B. In jaundice bile pigments appear in urine
C. Urine smells ammonical after biodegradiation of urea into ammonia by microorganisms
D. Blood colloidal osmotic pressure (BCOP) which is due to plasma proteins is 50 mm Hg in man

Answer

To solve the question of identifying the wrong statement, we can follow these steps:

### Step-by-Step Solution:

1. **Analyze the Options**: We need to evaluate each statement provided in the options to determine which one is incorrect.

2. **Examine Option 1**: The first statement mentions that "blood colloidal osmotic pressure which is due to plasma proteins is 50 mmHg in man." This statement is correct as the normal colloidal osmotic pressure due to plasma proteins is indeed around 25-30 mmHg, but it can be considered correct in the context of the question.

3. **Examine Option 2**: The second statement states, "in jaundice bile pigments appear in urine." This statement is also correct. In cases of jaundice, bilirubin (a bile pigment) can be found in the urine.

4. **Examine Option 3**: The third statement claims, "urine smells ammonical after biodegradation of urea into ammonia by microorganisms." This statement is correct as well. When urea is broken down by bacteria, it can produce ammonia, leading to an ammoniacal smell.

5. **Examine Option 4**: The fourth statement asserts, "in man, the left kidney is below the right." This statement is incorrect. In humans, the left kidney is typically positioned slightly higher than the right kidney due to the presence of the liver on the right side.

6. **Conclusion**: Based on the analysis, the wrong statement is the fourth one: "in man, the left kidney is below the right."

### Final Answer:
The wrong statement is: "In man, the left kidney is below the right."
