Physiology of Neutrophils, Macrophages, and Dendritic Cells

The video provides an overview of the innate immune system, focusing on the roles of neutrophils, macrophages, and dendritic cells. Neutrophils are described as primary phagocytes that attack pathogens through phagocytosis. Macrophages and dendritic cells also perform phagocytosis and are involved in antigen presentation, which helps identify and target specific pathogens. The video explains the process of diapedesis and the physical characteristics of these immune cells, highlighting their importance in the body's defense mechanisms.
