Physiological process that provides an individual with protection
Immunity
or defense from disease
- Proteins (pollens, food, venom, vaccines, transfusion
Normal physiological response
transplanted tissues)
to foreign antigens
- Microorganisms (bacteria, virus, parasites, fungi)
- Defense
- Homeostasis
Functions of an immune - Surveillance
response - Protect body from microorganisms/antigens
- Remove dead /damaged tissue/cells
- Recognizes and remove cell mutations
Optimal Immune Response Able to differentiate between host and foreign protein
- Ineffective immune response
- Not able to differentiate (blind)
Suppressed Immune Response - Failure to respond appropriately
- Immunosuppression/ immunodeficiency
- Infection
- Over/hyper functioning
- Not able to differentiate (suspicions)
- Attacks its own cells
Exaggerated Immune Response
- Hyperactive/ hyperimmune
- Allergy
- Autoimmune
Types of Immunity innate immunity and acquired immunity
Organs, tissues, and cells of the immune system that you are
Innate Immunity
born with (ex: skin)
Acquired Immunity Immunity that develops during your lifetime
Types of Acquired Immunity active and passive
Active Immunity Develops in response to an infection or vaccination
, Develops after you receive antibodies from someone or
Passive Immunity
somewhere else
Active Natural Immunity Antibodies developed in response to an infection
Active Artificial Immunity Antibodies developed in response to a vaccination
Passive Natural Immunity Antibodies received from mother (ex: through breast milk)
Antibodies received from a medicine (ex: from a gamma globulin
Passive Artificial Immunity
injection or infusion)
1.Non-specific physical and chemical defenses
Barriers to Invasion 2. Innate immunity
3. Adaptive immunity
Non-specific physical and - skin, mucous membrane, stomach acid, lysozyme in tears
chemical defenses - expulsion: coughing, sneezing, vomiting, diarrhea
- macrophages, neutrophils, eosinophils, basophils, monocytes
Innate immunity - complement system
- T cells
- cellular (cytotoxic)
Adaptive immunity - humoral (antibodies)
- T and B cells
- set of genes found on vertebrate DNA that code for cell
surface proteins essential for the adaptive immune system
Major histocompatibility
- play a crucial role in the immune response by presenting
complex
antigens (small peptide fragments) to T-cells, which then
recognize and respond to these antigens
- First barrier: skin and mucous membranes
- Second barrier: mononuclear phagocyte system (monocyte,
macrophage and dendritic cells)
- Lymphoid system
Components of the Immune
- Leukocytes
System
- Innate defenses
- Specific defenses: respond more effectively to 2nd exposure,
highly selective in ability to recognize antigens (B and T
lymphocytes)
- Primary organs: bone marrow and thymus gland
Organs of the Lymphoid System - Secondary organs: lymph nodes, spleen, tonsils, Peyer patches-
ileum (Gut-associated lymphoid tissue (GALT)
Lymphocytes produced from - T lymphocytes migrate to thymus to develop
stem cells - B cells and natural killer (NK) cells stay in marrow
- Primary cells of immune system
Leukocytes
- Formed from stem cells in bone marrow
