The kinds of cells that eat whatever foreign cells and molecules they encounter are red blood cells; natural killer cells; platelets; phagocytic cells; interferons Inflammatory responses may include: fever, dilation of the capillary secretions from macrophages, toxins released by pathogens, all of the above When you cut yourself, the damaged cells immediately release interferon, antibodies, histamine, pyrogens, anti-interferon

Explanation / Answer

14.limbic system concerned with emotions. 15.NK cells helps to increase apoptosis of malignant cells. Any decreased in NK cells causes production of malignant cells. Macrophages helps in immunity process . Other options are not belong to innate immunity. 16. Immune system recognised forgain body and respond with production of immune cells and proteins. Both are correct. 17.innate immunity found in both vertebrates and invertebrates. 18. The forgain body cells are eated by phagocytes. Neutrophils, macrophages, eosinophils , Dendritic cells are examples of phagocytic cells. 19. All are inflammatory responses . 20. Histamin is released immediately from cells when cells are damaged .
