Which one of the following is a correct pair showing the function of a specific part of the human nephron?

Options

A. Podocytes : Create minute spaces (slit pores) for the filtration of blood into the Bowman's capsule.
B. Henle's loop : most reabsorption of the major substances from the glomerular filtrate
C. Distal convoluted tubule : reabsorption of `K^(+)` ions tnto the surrounding blood capillaries
D. Afferent arteriole : carries the blood away from the glomerulus towards renal vein

Answer

To solve the question regarding the correct pair showing the function of a specific part of the human nephron, we need to analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Functions of Nephron Parts**:
- The nephron is the functional unit of the kidney, consisting of various parts, each with specific functions.

2. **Evaluate the Options**:
- **Option A: Podocytes create minute spaces or slit pores for the filtration of blood into the Bowman's capsule.**
- Podocytes are specialized cells that form part of the filtration barrier in the glomerulus. They do indeed create slit pores that allow for the filtration of blood into the Bowman's capsule.

- **Option B: Henle's loop is responsible for the most absorption of major substances from the glomerular filtrate.**
- The primary function of the loop of Henle is to concentrate urine and reabsorb water and salts, but it is not where the most absorption occurs; that happens in the proximal convoluted tubule (PCT).

- **Option C: Distal convoluted tubule (DCT) is responsible for the reabsorption of potassium ions into the surrounding blood capillaries.**
- The DCT does play a role in the reabsorption of ions, but it primarily involves the secretion of hydrogen ions and the regulation of sodium and potassium balance, rather than reabsorption of potassium.

- **Option D: Afferent arteriole carries blood away from the glomerulus towards the renal vein.**
- This statement is incorrect. The afferent arteriole carries blood towards the glomerulus, while the efferent arteriole carries blood away from it.

3. **Identify the Correct Answer**:
- Based on the analysis, **Option A** is the only correct statement regarding the function of a specific part of the nephron.

### Conclusion:
The correct pair showing the function of a specific part of the human nephron is **Option A: Podocytes create minute spaces or slit pores for the filtration of blood into the Bowman's capsule.**
