Invertebrates have an innate immune response that includes differentiation between pathogens and other cells. It also includes phagocytosis. Human innate immunity includes lymphocytes that practice the phagocytosis of pathogens.

Work Step by Step

Early invertebrates do not have an antibody-based adaptive immunity the way humans do, but they do have a complex innate immune system. One of the keys to this immune system is the ability to determine which cells are potentially dangerous, something that is crucial to human immunity as well. Additionally, invertebrates use phagocytosis as a part of this innate immunity, something also present in human innate immunity.
