Blood and immunity 3: innate immunity (textbook: pages 668-681) What is the role of the immune system: 1. What are the components of the immune system: 1. cells: Wide range of immune responses: 2. tissues: lymphoid. Bone marrow, thymus, spleen, lymph nodes, and tonsils. Lymphatic system-provides way for cells to be transported. Leukocyte development (except for final maturation of t lymphocytes: thymus. T lymphocyte development (immature t lymphocytes migrate here from the bone marrow) Peripheral lymphoid tissue: collections of b cells, t cells, and macrophages, trap microorganisms and foreign particles, expose them to leukocytes in high concentrations, spleen and lymph nodes. Get to know the enemy! (types of pathogens) Fungi antigens protein or polysaccharide components of viruses, bacteria, fungi, protozoa, parasitic worms, pollen, transplanted tissue, and tumor cells that can be identified by immune cells. What are the two major types of defenses: nonspecific defenses (innate immunity) rapid. Complement system: specific defenses (acquired immunity) slower.
