Loops of Henle present in

Options

A. Cortex
B. Medulla
C. Pelvis
D. Ureter

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of the Kidney**: The kidney is made up of two main regions: the cortex and the medulla. The cortex is the outer layer, while the medulla is the inner region.

2. **Identifying the Functional Unit**: The nephron is the functional unit of the kidney. Each nephron consists of several parts, including the Bowman's capsule, glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, collecting duct, and associated blood vessels.

3. **Locating the Loop of Henle**: The loop of Henle is a specific part of the nephron. It extends from the proximal convoluted tubule and dips down into the medulla before returning to the cortex.

4. **Determining the Location**: Since the loop of Henle dips into the medulla and is primarily located there, we can conclude that the loop of Henle is present in the medulla of the kidney.

5. **Evaluating the Options**: The question provides several options: cortex, medulla, pelvis, and uterus. Based on our understanding, the loop of Henle is found in the medulla.

6. **Final Answer**: The loop of Henle is present in the medulla.
