PATHOLOGY

Detailed explanation-1: -The cell types that characterize what pathologists term chronic inflammation primarily including lymphocytes, macrophages, and plasma cells (Fig. 3.4A). These leukocytes mediate innate as well as adaptive immunity. For historical reasons, pathologists continue to refer to macrophages as histiocytes.

Detailed explanation-2: -Neutrophils are continuously recruited to the site of chronic inflammation and contribute to driving the process through the release of serine proteases and the formation of neutrophil extracellular traps (NETs), as well as the activation of other immune cells.
