Which of the following is not a part of malpighian body?

Options

A. glomerulus
B. podocytes
C. bowman's capsule
D. macula densa

Answer

To determine which of the following is not a part of the Malpighian body, we first need to understand what the Malpighian body consists of. The Malpighian body, also known as the renal corpuscle, is primarily made up of two key components:

1. **Glomerulus**: This is a network of capillaries where the filtration of blood takes place. It is a crucial part of the Malpighian body.

2. **Bowman's Capsule**: This is a cup-like structure that encases the glomerulus and collects the filtrate that is produced during the filtration process.

Now, let's evaluate the options provided:

- **Glomerulus**: This is definitely a part of the Malpighian body.

- **Podocyte cells**: These are specialized cells that cover the glomerulus and play a role in filtration by preventing plasma proteins from entering the Bowman's capsule. They are also part of the Malpighian body.

- **Bowman's Capsule**: As mentioned earlier, this is a fundamental component of the Malpighian body.

- **Macula Densa**: This structure is located in the distal convoluted tubule of the nephron and is involved in regulating blood pressure and electrolyte balance. It does not form part of the Malpighian body.

Based on this analysis, the correct answer to the question "Which of the following is not a part of the Malpighian body?" is **Macula Densa**.

### Step-by-Step Solution:
1. Identify the components of the Malpighian body: Glomerulus and Bowman's capsule.
2. Evaluate each option to determine if it is part of the Malpighian body.
3. Confirm that Glomerulus and Bowman's capsule are parts of the Malpighian body.
4. Identify Podocyte cells as part of the Malpighian body.
5. Recognize that Macula Densa is not part of the Malpighian body.
6. Conclude that the answer is Macula Densa.
