About :

Phagocytosis is a key process in the immune system in which specialized cells known as phagocytes engulf and destroy invading pathogens, such as bacteria. Neutrophils and macrophages are examples of professional phagocytes, whose primary function is to perform efficient phagocytosis. Neutrophils are highly mobile and abundant white blood cells that respond rapidly to signals of inflammation and infection. They are the first to arrive at the site of infection and work eagerly to engulf and destroy invaders. Macrophages, on the other hand, are phagocytic cells found in many tissues throughout the body. They trigger a more sustained immune response, acting both in phagocytosis and in presenting antigens to other cells of the immune system. In addition to eliminating pathogens, macrophages also play a crucial role in regulating inflammation and wound healing. In summary, both neutrophils and macrophages are highly specialized professional phagocytes, essential for the defense of the organism against infectious agents and for the maintenance of immunological homeostasis.
