Macrophages are the primary phagocytic cells that engulf and digest cellular debris and pathogens, handling cleanup and helping to kickstart the immune response by presenting pieces of invaders to other immune cells. They come from monocytes and live in tissues as histiocytes, always ready to clear debris and microbes. Lymphocytes, while essential for adaptive immunity, specialize in targeted responses like antibody production or T cell–mediated actions rather than general phagocytosis. Lymph is the fluid in the lymphatic system, not a cell. The thoracic duct is a major lymphatic vessel that transports lymph, not a cellular component.
