Find the correct answer about glomerular filtrate
1. Formed continuously through ultrafilration of blood
2. Liquid free fluid collects in the lumen of Bowman's capsule
3. Protein free fluid collects in the lumen of Bowman's capsule
4. formed by process of selective reabsorption

Options

A. 1, 2, 3 correct
B. 1, 2 correct
C. 2, 4 correct
D. 1, 3 correct

Answer

To solve the question regarding glomerular filtrate, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement 1: Formed continuously through ultrafiltration of blood.**
- This statement is correct. Glomerular filtrate is indeed formed continuously through the process of ultrafiltration, which occurs in the glomerulus of the nephron. During this process, blood is filtered, and the filtrate is collected.

2. **Statement 2: Liquid free fluid collects in the lumen of Bowman's capsule.**
- This statement is incorrect. The filtrate that collects in Bowman's capsule is not just a "liquid free fluid." It is a protein-free fluid, meaning that while it is a liquid, it does not contain proteins due to the filtration process that prevents larger molecules from passing through.

3. **Statement 3: Protein free fluid collects in the lumen of Bowman's capsule.**
- This statement is correct. The glomerular filtrate that collects in Bowman's capsule is indeed protein-free. This is a result of the selective permeability of the glomerular membrane, which allows water and small solutes to pass while retaining larger molecules like proteins.

4. **Statement 4: Formed by the process of selective reabsorption.**
- This statement is incorrect. Glomerular filtrate is not formed by selective reabsorption; rather, it is formed by ultrafiltration. Selective reabsorption occurs later in the nephron, where certain substances are reabsorbed back into the bloodstream after the filtrate has been formed.

### Conclusion:
Based on the analysis, the correct statements about glomerular filtrate are:
- Statement 1 is correct.
- Statement 3 is correct.
- Statements 2 and 4 are incorrect.

Thus, the correct answer is that statements 1 and 3 are true regarding glomerular filtrate.
