Which of the following is NOT part of the inflammatory response?
A
Increased phagocytic activity by neutrophils
B
Decreased blood flow to the affected area
C
Release of histamine by mast cells
D
Vasodilation of blood vessels
Verified step by step guidance1
Understand the inflammatory response: The inflammatory response is a defense mechanism triggered by the immune system to protect the body from injury or infection. It involves several processes, including increased blood flow, vasodilation, and recruitment of immune cells.
Analyze the options: Review each option provided in the question and determine whether it aligns with the typical processes of the inflammatory response.
Option 1: Increased phagocytic activity by neutrophils - This is part of the inflammatory response, as neutrophils are recruited to the site of injury or infection to engulf and destroy pathogens.
Option 3: Release of histamine by mast cells - Histamine is released by mast cells during inflammation, leading to vasodilation and increased permeability of blood vessels.
Option 4: Vasodilation of blood vessels - Vasodilation is a hallmark of the inflammatory response, allowing more blood to flow to the affected area. Option 2, 'Decreased blood flow to the affected area,' is NOT part of the inflammatory response, as blood flow typically increases during inflammation.
