The glomerular filtrate i.e., the liquid collected in the cavity of Bowman's capsule is

Options

A. plasma
B. urine
C. blood minus proteins
D. blood minus proteins and corpuscles

Answer

To answer the question regarding the nature of the glomerular filtrate collected in the cavity of Bowman's capsule, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Blood Composition**:
- Blood is composed of various components, including plasma, red blood cells, white blood cells, and platelets. Plasma is the liquid part of blood that contains water, salts, and proteins.

2. **Function of the Nephron**:
- The nephron is the functional unit of the kidney responsible for filtering blood and forming urine. Each nephron contains a glomerulus and a tubule.

3. **Filtration Process in the Glomerulus**:
- The glomerulus is a network of capillaries where the filtration of blood occurs. During this process, blood enters the glomerulus, and due to high pressure, a portion of the plasma is forced out into the Bowman's capsule.

4. **Components of Glomerular Filtrate**:
- The filtrate that enters Bowman's capsule is primarily composed of water, electrolytes, glucose, amino acids, and waste products. Importantly, it does not contain large molecules such as proteins and blood cells, as these are too large to pass through the filtration barrier.

5. **Conclusion**:
- Therefore, the glomerular filtrate can be described as "blood minus proteins and corpuscles," which means it is essentially plasma without the larger components (proteins and blood cells).

### Final Answer:
The glomerular filtrate, i.e., the liquid collected in the cavity of Bowman's capsule, is **blood minus proteins and corpuscles**.
