Hemocytes are specialized blood cells found in invertebrates, such as insects and mollusks. They play a crucial role in the immune response, helping to defend the organism against pathogens and foreign substances. Hemocytes can be involved in processes like phagocytosis, where they engulf and digest harmful particles. In addition to their immune functions, hemocytes are also important for wound healing and tissue repair. They can release signaling molecules that promote healing and help to form clots, preventing excessive blood loss. Overall, hemocytes are essential for maintaining the health and survival of invertebrate species.
