Select the incorrect match w.r.t disorders of the excretory system.

Options

A. Uremia - Accumulation of uric acid in blood
B. Renal calculi - Crystallised salts of calcium oxalate
C. Glomerulonephritis - Inflammation of glomeruli
D. Glycosuria - Glucose in urine

Answer

To solve the question of identifying the incorrect match with respect to disorders of the excretory system, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Uremia**:
- Uremia is a condition characterized by the accumulation of urea in the blood due to kidney malfunction.
- The statement claims that uremia is the accumulation of uric acid in the blood. This is incorrect because uremia specifically refers to urea, not uric acid.

2. **Analyzing Renal Calculi**:
- Renal calculi, commonly known as kidney stones, are formed from crystallized salts.
- The statement correctly describes renal calculi as an insoluble mass of crystallized salts, which can include calcium oxalate.

3. **Confirming the Composition of Renal Calculi**:
- The statement mentions that renal calculi can consist of salts of calcium oxalate, which is accurate.
- Therefore, this match is correct.

4. **Examining Glomerulonephritis**:
- Glomerulonephritis is an inflammation of the glomeruli in the kidneys.
- The statement correctly describes glomerulonephritis as inflammation of glomeruli, making this match correct.

5. **Understanding Glycosuria**:
- Glycosuria refers to the presence of glucose in urine, which occurs when the blood glucose level is high, and the kidneys cannot reabsorb all the glucose.
- The statement correctly defines glycosuria as the presence of glucose in urine, confirming this match is also correct.

### Conclusion:
- The incorrect match is the first one: **Uremia, accumulation of uric acid in blood**. The correct definition should be the accumulation of urea in the blood.

### Final Answer:
The incorrect match is: **1. Uremia, accumulation of uric acid in blood**.
