Glomerular filtrate contains

Options

A. all the constituents of plasma
B. all the constituents of blood
C. similar to the features of serum
D. all the constituents of plasma excluding larger proteins

Answer

**Step-by-Step Solution:**

1. **Understanding Glomerular Filtrate:**
- Glomerular filtrate is the fluid that is filtered from the blood through the glomerulus into the Bowman's capsule in the nephron of the kidney.

2. **Components of Blood:**
- Blood consists of various components, including red blood cells, white blood cells, platelets, plasma, and proteins.

3. **Filtration Process:**
- During the filtration process, blood enters the nephron through the afferent arteriole and is filtered in the glomerulus. The pressure in the glomerulus forces water and small solutes out of the blood and into the Bowman's capsule.

4. **What is Excluded:**
- Larger proteins and blood cells are too large to pass through the filtration membrane and therefore do not enter the Bowman's capsule.

5. **Composition of Glomerular Filtrate:**
- The glomerular filtrate contains all the constituents of plasma except for larger proteins and blood cells. This includes water, electrolytes, glucose, amino acids, and small molecules.

6. **Conclusion:**
- Therefore, the correct answer to the question "Glomerular filtrate contains" is that it contains all constituents of plasma excluding larger proteins.

**Final Answer:**
- Glomerular filtrate contains all constituents of plasma excluding larger proteins.
