ANATOMY

Detailed explanation-1: -10.3. The inflammatory response is characterized in part by local vasodilation and the accumulation of white blood cells at the site of insult. White blood cells, in particular, macrophages and neutrophils, accumulate at the site of “insult” via a process known as chemotaxis.

Detailed explanation-2: -Phagocytes are a group of white blood cells that includes neutrophils. These cells consume bacteria and other pathogens to protect the body from infection. The process begins when chemicals from a pathogen, or damaged tissue, attract a phagocyte. The phagocyte binds to the microbe, envelopes it, and then eats it.

Detailed explanation-3: -Cell types in inflammatory responses The first cells attracted to a site of injury are neutrophils, followed by monocytes, lymphocytes (natural killer cells [NK cells], T cells, and B cells), and mast cells [71–73].

Detailed explanation-4: -Neutrophils. These cells are most abundant and effective during the inflammation and phagocytosis processes. Neutrophils (PMN) are characterized as being the first cell line that is recruited at the inflammation site after chemotactic stimuli.
