Shaped of Henle 's loop and vasa recta is

Options

A. C' shaped and 'U' shaped respectively
B. U' shaped and 'C' shaped respectively
C. Hairpin shaped and 'U' shaped respectively
D. U' shaped and hairpin shaped respectively

Answer

**Step-by-Step Solution:**

1. **Understanding the Nephron**: The nephron is the structural and functional unit of the kidney, responsible for the excretion of waste products and regulation of water and electrolytes in the body.

2. **Identifying Key Structures**: Within the nephron, there are several key components, including the Bowman's capsule, proximal convoluted tubule (PCT), loop of Henle, distal convoluted tubule (DCT), and the collecting duct.

3. **Describing the Loop of Henle**: The loop of Henle is a U-shaped structure that plays a critical role in the concentration of urine. It consists of a descending limb and an ascending limb, forming a U shape.

4. **Describing the Vasa Recta**: The vasa recta are blood vessels that surround the loop of Henle. Their shape resembles a hairpin, as they curve around the loop of Henle, facilitating the exchange of substances between the blood and the filtrate.

5. **Conclusion**: Therefore, the shapes of the structures in question are:
- **Henle's Loop**: U-shaped
- **Vasa Recta**: Hairpin-shaped

6. **Final Answer**: The correct answer is that Henle's loop is U-shaped and the vasa recta has a hairpin shape.
