Which of the following is not considered as component of tubular parts of nephron?

Options

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

Answer

To determine which of the following is not considered a component of the tubular parts of the nephron, we need to identify the structures that make up the nephron and categorize them accordingly.

### Step-by-Step Solution:

1. **Understand the Nephron Structure**: The nephron is the functional unit of the kidney, consisting of several parts that play specific roles in the filtration and excretion of waste from the blood.

2. **Identify the Components**:
- **Bowman's Capsule**: This is a cup-like structure that encases the glomerulus and is involved in the initial filtration of blood.
- **Glomerulus**: A network of capillaries located within the Bowman's capsule where ultrafiltration occurs. It is not tubular in structure.
- **Proximal Convoluted Tubule (PCT)**: A tubular structure that reabsorbs nutrients, water, and ions from the filtrate.
- **Loop of Henle**: A U-shaped tubular structure that concentrates urine and reabsorbs water and salts.
- **Distal Convoluted Tubule (DCT)**: Another tubular structure that further modifies the filtrate by reabsorbing more ions and water.
- **Collecting Duct**: A tubular structure that collects urine from multiple nephrons and channels it to the renal pelvis.

3. **Identify the Non-Tubular Component**: Among the components listed (PCT, DCT, glomerulus, loop of Henle), the glomerulus is the only structure that is not tubular. It is a cluster of capillaries and does not have a tube-like structure.

4. **Conclusion**: Therefore, the component that is not considered a part of the tubular parts of the nephron is the **glomerulus**.

### Final Answer:
**Glomerulus**
