Which of the following is not a part of renal tubules?
(a) Glomerulus
(b) PCT
(c) DCT
(d) Loop of Henle

Options

A. Glomerulus
B. PCT
C. DCT
D. Loop of Henle

Answer

To solve the question "Which of the following is not a part of renal tubules?", we can follow these steps:

### Step 1: Understand the Components of a Nephron
A nephron is the functional unit of the kidney and consists of several parts, including the renal tubules and the glomerulus.

### Step 2: Identify the Parts of Renal Tubules
The renal tubules are made up of:
- Proximal Convoluted Tubule (PCT)
- Loop of Henle
- Distal Convoluted Tubule (DCT)
- Collecting Duct

### Step 3: Analyze Each Option
- **(a) Glomerulus**: This is a tuft of capillaries located within the Bowman's capsule and is not part of the renal tubules.
- **(b) PCT**: This is part of the renal tubules.
- **(c) DCT**: This is also part of the renal tubules.
- **(d) Loop of Henle**: This is part of the renal tubules as well.

### Step 4: Conclusion
Since the glomerulus is not a part of the renal tubules, the correct answer is **(a) Glomerulus**.

### Final Answer
**(a) Glomerulus**
