A Malpighian body is constitued by

Options

A. Glomerulus only
B. glomerulus and Bowman's capsule
C. glomerulus and efferent vessel
D. glomerulus, Bowman's capsule and efferent vessel.

Explanation

To answer the question about what constitutes a Malpighian body, we can break down the information step by step.

### Step-by-Step Solution:

1. **Understanding the Nephron**:
- The nephron is the functional unit of the kidney. It is essential for the filtration of blood and the formation of urine.

2. **Components of the Nephron**:
- The nephron consists of two main parts: the renal corpuscles and the renal tubules. The renal corpuscle is also known as the Malpighian body.

3. **Structure of the Malpighian Body**:
- The Malpighian body is made up of a double-walled cup-like structure known as the Bowman's capsule.

4. **Presence of Capillaries**:
- Inside the Bowman's capsule, there is a network of capillaries called the glomerulus. This is where the filtration of blood takes place.

5. **Blood Flow**:
- Blood enters the glomerulus through the afferent arteriole and exits through the efferent arteriole.

6. **Conclusion**:
- Therefore, the Malpighian body is constituted by the glomerulus and the Bowman's capsule.

### Final Answer:
The Malpighian body is constituted by the glomerulus and the Bowman's capsule.
