Explain the autoregulatory mechanism of GFR.

Explanation

### Step-by-Step Solution:

1. **Understanding GFR**:
- GFR stands for Glomerular Filtration Rate, which is the rate at which blood is filtered in the kidneys. It is measured in milliliters per minute and indicates how well the kidneys are functioning.

2. **Role of Nephrons**:
- The functional unit of the kidney is the nephron. Each nephron contains a glomerulus, which is a network of capillaries where filtration occurs. The filtrate produced in the glomerulus enters the Bowman's Capsule.
