Understanding the Answer
Let's break down why this is correct
Answer
Natural killer cells attack infected or cancerous cells, so inflammation is the body’s way of attacking infected or damaged tissue. When a pathogen or a damaged cell is detected, inflammatory cells release cytokines and recruit more immune cells to the site. This process helps remove the threat and begins healing. For example, after a bacterial bite, inflammation brings neutrophils and macrophages to destroy the bacteria and clean up the tissue. Thus, inflammation targets pathogens and injured cells to protect and repair the body.
Detailed Explanation
Inflammation makes the area hot, swollen and filled with immune cells. Other options are incorrect because Many think inflammation tells the adaptive immune system to arrive; Some believe inflammation stops all infections.
