Macrophages are cells from the immune system that recognize and eliminate strange elements. Option A. Inflammatory responses typically include increased activity of phagocytes in an inflamed area.
Macrophages are one type of white globules involved in the organism's defense against strange substances and pathogen agents. They are the principal actors in the immune response.
Macrophages recognize different strange molecules that penetrate the organism (bacterias, parasites, and viruses), phagocyte and eliminate them. This process known as phagocytosis.
When macrophages are activated, they release cytokines that favor inflammation response, neutralizing the pathogen agent and removing damaged tissue from the affected area.
Together with inflammation, there is a change in blood flow, increasing the permeability of blood vessels, and enhacing the migration of fluid, proteins, and other immune cells to the affected area.
The correct option is A. Inflammatory responses typically include the increased activity of phagocytes in an inflamed area.
