Cortisol does not cause

Options

A. Anti-flammatory reactions
B. Proteolysis
C. Enhanced RBC production
D. Enhanced phagocytic activity of WBCs

Answer

To solve the question "Cortisol does not cause," we need to analyze the functions of cortisol and determine which option is not associated with its effects.

### Step-by-Step Solution:

1. **Understand Cortisol**: Cortisol is a steroid hormone produced by the adrenal cortex, specifically from the zona fasciculata. It plays a significant role in various physiological processes in the body.

2. **Evaluate the Options**:
- **Anti-inflammatory Reactions**: Cortisol is known to have anti-inflammatory properties. It inhibits inflammation by blocking the release of substances that cause inflammation. Therefore, this option is incorrect as cortisol does cause anti-inflammatory reactions.

- **Proteolysis**: Cortisol promotes proteolysis, which is the breakdown of proteins into amino acids. This process occurs particularly when glucose levels are low, and the body needs to mobilize energy. Thus, this option is also incorrect as cortisol does cause proteolysis.

- **Enhanced RBC Production (Erythropoiesis)**: Cortisol has a role in promoting erythropoiesis, which is the production of red blood cells. Therefore, this option is incorrect as cortisol does cause enhanced RBC production.

- **Enhanced Phagocytic Activity of WBCs**: Cortisol does not enhance the phagocytic activity of white blood cells (WBCs). In fact, high levels of cortisol can suppress the immune response, including the activity of WBCs. This option is correct because cortisol does not cause enhanced phagocytic activity.

3. **Conclusion**: Based on the analysis of the options, the correct answer to the question "Cortisol does not cause" is **Enhanced Phagocytic Activity of WBCs**.

### Final Answer:
Cortisol does not cause enhanced phagocytic activity of WBCs.
