Final answer:
An infected wound typically contains pus, dead neutrophils, cellular debris, tissue fluids, and is a site where neutrophils have actively engaged in phagocytosing pathogens before dying off, contributing to the pus formation.
Step-by-step explanation:
An infected wound typically contains pus, which is an accumulation of dead pathogens, neutrophils, tissue fluid, and various other cells that may have been destroyed during the immune response. The presence of pus signifies a severe local infection where neutrophils have been recruited in large numbers. These neutrophils, which are phagocytic immune cells, consume pathogens and die off, leaving their cellular remnants, along with that of other dead cells and tissue fluids, to form pus at the site of the infection. Moreover, as part of the inflammatory response, increased vascular permeability promotes the entry of clotting factors that begin wound repair and facilitates the transport of antigens to lymph nodes, contributing to the adaptive immune response.
