Inflammatory response
Second line of defense. Is activated when pathogens manage to enter the body, multiply, and release toxins into tissues. The inflammatory response is a nonspecific defense reaction to tissue damage caused by injury or infection. White blood cells increase, phagocytes engulf and destroy bacteria. Core body temp is increased.
The inflammatory response is a complex biological process that occurs when the body’s natural defense mechanism against harmful stimuli, such as pathogens, damaged cells, or irritants, is activated. The response works by bringing blood flow and immune cells to the affected area, which helps to remove the stimulus and initiate healing.
The inflammatory response is initiated by the release of chemical mediators, such as cytokines and chemokines, by immune cells and damaged tissue. These mediators signal nearby blood vessels to dilate, which increases blood flow to the affected area. The increased blood flow causes redness and warmth of the affected area.
The immune cells that are called to the area through the chemical mediators, including neutrophils and macrophages, help to engulf and destroy the harmful stimuli. This can result in the formation of pus and swelling of the area.
The inflammatory response is a necessary and crucial part of the body’s immune system. It stimulates the body’s protective mechanisms to fight off harmful stimuli and initiate the healing process. However, excessive or prolonged inflammation can cause tissue damage and lead to chronic conditions such as arthritis and cardiovascular disease.
