Question

What is the first step in the major events of the inflammatory process?

A) Scar formation and/resolution
B) Formation of pus and Edema
C) Injury and mast cells releasing chemical mediators
D) Activation of complement

Answer 1

The first step in the inflammatory process is tissue injury leading to the release of chemical mediators by mast cells, which results in redness, warmth, swelling, and pain at the site of damage.

Step-by-step explanation:

The first step in the major events of the inflammatory process is Injury and mast cells releasing chemical mediators.

Inflammation starts when there is tissue injury. The injured cells release chemicals that signal the beginning of the inflammatory response. Mast cells play a crucial role at this stage by releasing potent mediators such as histamine, leukotrienes, and prostaglandins, which lead to vasodilation, increased blood flow, and greater capillary permeability that causes redness, warmth, and swelling — the hallmarks of inflammation.

Further, these chemical signals attract white blood cells to the site to manage the injury, leading to an influx of immune cells such as neutrophils and macrophages. This process ideally leads to the elimination of pathogens and repair of the injured tissue. If resolution does not occur, the inflammation may become chronic, leading to possible tissue damage and scarring.

Answer 2

B. Reason being if you look at major examples of inflammatory processes such as strep, you can see the presence of such
