Part not belonging to uriniferous tubule is

Options

A. glomerulus
B. Henle's loop
C. distal convoluted tubule
D. collecting tubule

Explanation

To determine which part does not belong to the uriniferous tubule (nephron), we need to identify the components of the nephron and differentiate them from other structures associated with the kidney.

### Step-by-Step Solution:

1. **Understanding the Nephron**:
- The nephron is the functional and structural unit of the kidney responsible for urine formation. It consists of several parts.

2. **Identifying the Parts of the Nephron**:
- The main parts of the nephron include:
- **Glomerulus**: A tuft of capillaries where filtration of blood occurs.
- **Bowman's Capsule**: A cup-like sac that encases the glomerulus.
- **Proximal Convoluted Tubule (PCT)**: The first segment of the renal tubule where reabsorption of water, ions, and nutrients occurs.
- **Loop of Henle**: A U-shaped tube that consists of a descending limb and an ascending limb, playing a crucial role in concentrating urine.
- **Distal Convoluted Tubule (DCT)**: The segment following the loop of Henle, involved in further reabsorption and secretion.

3. **Identifying the Collecting Duct**:
- The **Collecting Duct** is a structure that collects urine from multiple nephrons. It is not a part of a single nephron but rather serves multiple nephrons.

4. **Conclusion**:
- Since the collecting duct is not a part of the nephron but rather collects urine from several nephrons, it is the correct answer to the question of which part does not belong to the uriniferous tubule.

### Final Answer:
The part that does not belong to the uriniferous tubule is the **Collecting Duct**.
