Detailed explanation-1: -Their common origin also explains that these two professional phagocytes share several characteristics: (i) Like macrophages, neutrophils are avidly phagocytic, and both phagocytes use a large array of antimicrobial mechanisms that involve oxidants, granule proteins, and iron-withholding molecules (reviewed in refs.
Detailed explanation-2: -Answer and Explanation: Of the above answer choices, the one that is not a function performed by macrophages is e. They produce antibodies that bind to specific antigens. Plasma B cells and not macrophages are the cells that produce antibodies that bind specific antigens in the body’s fluids.
Detailed explanation-3: -Macrophages are specialised cells involved in the detection, phagocytosis and destruction of bacteria and other harmful organisms. In addition, they can also present antigens to T cells and initiate inflammation by releasing molecules (known as cytokines) that activate other cells.
