Introduction A system of biological structures that defends organisms from disease causing particles. Organisms can have innate immunity alone or with the addition adaptive immunity.
3
Cnidarians- Jellies Very primitive immune system. May conduct phagocytosis against foreign particles.
4
Annelida- Oligochaete (earthworm) Have innate immunity. Acquires cellular immunity through phagocytosis. May have spontaneous cytotoxicity.
5
Arthopoda- Fruit Flies Develops more complex innate immunity with barrier defenses have hemocytes to perform phagocytosis.
6
Mammalia- Humans Have more complex immune system with the addition of adaptive immunity. Have immunological memories of previous infections. Includes various interdependent relationships with other organ systems.
7
Innate Immunity Occurs in all animals and is immediately active infection exposure. Does not target specific pathogens. No immunological memory.
8
Innate Immunity (Continued) Barrier Defenses: Internal Defenses:
9
Inflammation
10
Adaptive Immunity Found only in vertebrates and targets specific pathogens. Have immunological memory of previous infection exposure.
11
Adaptive Immunity (Continued) The cells are lymphocytes and are formed in the bone marrow. These includes B cells and T cells.
12
Adaptive Immunity (Overview)
13
B Cells (Recognition and Response)
14
T Cells (Recognition and Response) Helper T CellsCytotoxic T Cells Response Killer
15
Immune Response Further exposure to a specific antigen from a pathogen causes the increase production of certain antibodies.
16
Immune System Structures Includes: bone marrow, thymus, spleen, and lymph nodes.
17
Interdependence with Other Systems
18
Active and Passive Immunity Active Passive Long lasting immunity, resulted by memorization for specific pathogens. Short term immunity, where antibodies are transferred from mother to offspring.
