Assertion A. The process of filtration takes place in malpighian corpuscles
Reason R. The total blood pressure is very high in glomerular capillaries

Options

A. A is wrong and R is correct
B. A and R are correct. R is not explanation of A
C. A is correct and R is wrong
D. A and R both are correct. R is correct explanation of A

Answer

To analyze the given assertion and reason, let's break down the information step by step:

### Step 1: Understanding the Assertion
- **Assertion (A)**: The process of filtration takes place in malpighian corpuscles.
- **Explanation**: Malpighian corpuscles, also known as renal corpuscles, consist of the glomerulus and Bowman's capsule. They are essential components of the nephron in the kidney where filtration occurs.

### Step 2: Understanding the Reason
- **Reason (R)**: The total blood pressure is very high in glomerular capillaries.
- **Explanation**: The glomerular capillaries are specialized to have a high blood pressure due to their unique structure and the afferent arterioles leading into them. This high pressure is crucial for the filtration process, as it forces water and solutes out of the blood and into the Bowman's capsule.

### Step 3: Evaluating the Relationship
- Both the assertion and reason are true statements.
- The reason (high blood pressure in glomerular capillaries) directly supports the assertion (filtration occurs in malpighian corpuscles) because the high pressure is what enables the filtration process to take place effectively.

### Conclusion
- Both the assertion and reason are correct, and the reason provides a correct explanation for the assertion. Therefore, the correct answer is that both the assertion and reason are correct, and the reason is the correct explanation of the assertion.
