Expand the following terms :
JGA

Answer

### Step-by-Step Solution:

1. **Identify the Term**: The term we need to expand is "JGA".

2. **Full Form**: The full form of JGA is "Juxtaglomerular Apparatus".

3. **Understanding the Components**: The Juxtaglomerular Apparatus is a structure located in the nephron of the kidney. It consists of two main components:
- **Distal Convoluted Tubule (DCT)**: This is a part of the nephron that comes after the loop of Henle and is involved in the reabsorption of sodium and water.
- **Afferent Arteriole**: This is a small artery that carries blood to the glomerulus of the nephron.

4. **Function of JGA**: The Juxtaglomerular Apparatus plays a crucial role in:
- **Regulating Blood Pressure**: It helps in the regulation of blood pressure within the kidneys.
- **Controlling Glomerular Filtration Rate (GFR)**: It also helps in controlling the rate at which blood is filtered through the glomeruli.

5. **Conclusion**: Therefore, the expanded form of JGA is "Juxtaglomerular Apparatus", which is essential for maintaining homeostasis in the body by regulating blood pressure and filtration in the kidneys.
