Proximal convoluted tubule, distal convoluted tubule, Henle's loop, renal corpuscle.

Answer

### Step-by-Step Solution

1. **Identify the Components**: The question lists four components: proximal convoluted tubule, distal convoluted tubule, Henle's loop, and renal corpuscle. These are all parts of the nephron, which is the functional unit of the kidney.

2. **Understand the Structure of the Nephron**: The nephron is divided into two main parts:
- **Renal Corpuscle**: This is where the filtration of blood occurs.
- **Renal Tubular Part**: This is where reabsorption and secretion processes take place.

3. **Detail the Renal Corpuscle**: The renal corpuscle consists of:
- **Glomerulus**: A tuft of capillaries where filtration occurs.
- **Bowman’s Capsule**: A capsule-like structure that encloses the glomerulus.

4. **Explore the Renal Tubular Part**: The renal tubular part is divided into three main sections:
- **Proximal Convoluted Tubule (PCT)**: This is where the reabsorption of essential minerals and nutrients occurs. It can be further divided into:
- Proximal Convoluted Tubule (PCT)
- Proximal Straight Tubule
- **Henle's Loop**: This section is responsible for the reabsorption of water, which helps concentrate the urine.
- **Distal Convoluted Tubule (DCT)**: This is also divided into:
- Distal Convoluted Tubule
- Distal Straight Tubule
- This part is involved in the reabsorption and secretion of ions such as sodium, potassium, chloride, and bicarbonate.

5. **Summarize the Functions**:
- **Renal Corpuscle**: Filtration of blood.
- **Proximal Convoluted Tubule**: Reabsorption of nutrients and minerals.
- **Henle's Loop**: Concentration of urine through water reabsorption.
- **Distal Convoluted Tubule**: Reabsorption and secretion of various ions.
