Answer

To solve the matching question, we will analyze each part of the nephron and its corresponding function. Here’s a step-by-step breakdown:

1. **Loop of Henle (A)**:
- The Loop of Henle is primarily responsible for the concentration of urine. It helps in creating a concentration gradient in the medulla of the kidney, which allows for the reabsorption of water and solutes, thus concentrating the urine.
- **Match**: Loop of Henle → Plays a role in concentration of urine (5).

2. **Renal Artery (B)**:
- The renal artery carries blood to the kidneys from the aorta. It is the blood vessel that supplies the kidneys with blood for filtration.
- **Match**: Renal artery → Carries blood to the kidney (1).

3. **Proximal Convoluted Tubule (C)**:
- The proximal convoluted tubule (PCT) is the site where a significant amount of reabsorption occurs. It reabsorbs water, ions, and nutrients from the filtrate back into the blood.
- **Match**: Proximal convoluted tubule → Area of high amount of reabsorption takes place (2).

4. **Glomerulus (D)**:
- The glomerulus is a network of capillaries located at the beginning of the nephron. It is responsible for the filtration of blood, where the blood plasma is filtered to form urine.
- **Match**: Glomerulus → Filtration of blood (4).

5. **Distal Convoluted Tubule (E)**:
- The distal convoluted tubule (DCT) is involved in the secretion of ions, particularly potassium (K⁺) and hydrogen (H⁺), and it plays a role in the final adjustments of urine concentration under the influence of hormones like aldosterone.
- **Match**: Distal convoluted tubule → Main area of K⁺ and H⁺ secretion (3).

Now, putting it all together, we have the following matches:
- A → 5 (Loop of Henle → Plays a role in concentration of urine)
- B → 1 (Renal artery → Carries blood to the kidney)
- C → 2 (Proximal convoluted tubule → Area of high amount of reabsorption takes place)
- D → 4 (Glomerulus → Filtration of blood)
- E → 3 (Distal convoluted tubule → Main area of K⁺ and H⁺ secretion)

Thus, the correct pairing sequence is:
**5, 1, 2, 4, 3**.
