Which of the following is part of the inflammatory response?

• A. Vasodilation
• B. Decreased blood flow
• C. Decreased white blood cell activity
• D. Reduced vascular permeability

Answer: (A)

Verified step by step guidance

1. Understand the inflammatory response: It is a biological process that occurs in response to harmful stimuli, such as pathogens, damaged cells, or irritants. The goal is to eliminate the initial cause of cell injury, clear out damaged cells and tissues, and establish repair.
2. Identify the key components of the inflammatory response: These include vasodilation, increased vascular permeability, and the recruitment of white blood cells to the site of injury or infection.
3. Analyze the options given: Vasodilation, decreased blood flow, decreased white blood cell activity, and reduced vascular permeability.
4. Evaluate each option: Vasodilation is a hallmark of the inflammatory response, leading to increased blood flow to the affected area. This helps deliver immune cells and nutrients necessary for healing.
5. Conclude by identifying the correct option: Vasodilation is the correct answer as it is a fundamental part of the inflammatory response, unlike the other options which are contrary to the typical physiological changes observed during inflammation.
