**Question:** An acute inflammation would attract

A. White blood cells (neutrophils)
B. Mast cells
C. Mast cells
D. Platelets

**Core Concept:** Inflammation is a defense mechanism of the body against pathogens, tissue damage, or other harmful stimuli. It is a protective response that aims to eliminate the cause of injury, remove dead tissue and foreign particles, and promote healing.

**Why the Correct Answer is Right:** Acute inflammation is a rapid, intense, and self-limiting response to an injury or infection. It is characterized by redness, heat, swelling, pain, and loss of function. In acute inflammation, neutrophils are the primary cells involved in the inflammatory process. These white blood cells are crucial in phagocytosis (the engulfing and destruction of pathogens) and releasing inflammatory mediators that attract more immune cells to the site of injury or infection.

**Why Each Wrong Option is Incorrect:**

B. Mast cells are involved in anaphylaxis (immediate hypersensitivity reactions) and release histamine, heparin, and proteases upon activation. They do not contribute to acute inflammation directly.

C. Mast cells are similar to mast cells, but unlike mast cells, mast cells are involved in anaphylaxis and do not play a significant role in acute inflammation.

D. Platelets are involved in hemostasis (blood clotting) and do not directly contribute to acute inflammation or the recruitment of immune cells.

**Clinical Pearl:** Understanding the role of immune cells in inflammation is crucial for diagnosing and treating inflammatory conditions. Acute inflammation often leads to a subsequent phase of chronic inflammation, which involves other immune cells like macrophages and lymphocytes.
