- 1Immune Systemare organs, tissues, and cells that work together to prevent illnesses
- 2What does the Immune System include?• White blood cells
• Lymph nodes
• Tonsils
• Thymus gland
• Bone marrow
• Spleen - 3Thymus Glandmakes T-cells (lymphocytes)
- 4Bone Marrowmakes B-cells
- 5Spleenfilters blood, and destroys bacteria
- 6Diseaseis any change that disrupts the normal functioning of the body
- 7What are some examples of Pathogens?• Virus (EX: varicella, herpes)
• Bacteria (EX: E. coli, tetanus)
• Fungi (EX: athlete’s foot)
• Parasites (EX: worms, lice) - 8How does the Immune System work?• Human bodies have 3 lines of defenses
• 1st line is the barrier
• 2nd line is the inflammatory response
• 3rd line is the immune response - 91st Line of Defense• Is the barriers
• Skin keeps things out
• Chemicals like sweat and tears are neutralized pathogens
• Mucus & cilia – traps pathogens - 102nd Line of Defense• Is a Inflammatory Response
• Macro phage devours germ
• Inflammation
• Fever - 113rd Line of Defense• Is a Immune Response
• Has a specific immune response (which means that the body responds to a specific pathogen or antigen)
• Has antigens - 12Macrophagedevours invaders, and launches the immune system attack
- 13Helper T Cellscoordinate immune system attacks by activating other immune system cells
- 14Antibodiesattach themselves to the foreign substance
- 15B Cellstag invaders with antibodies, so that other immune system cells will know that they have to destroy them
- 16Antigensare a substance made by pathogens that cause harm, and are exposed to identify the invader
- 17Killer T Cellsdevoursinvaders, or release toxic chemicals that kill the invaders
- 18Memory T Cellsmakes immune responses faster the next time an invader comes around
- 19What are the types of Immunity?• Passive immunity – immunity that is temporary; it is when the immunity is transferred from another person
(EX: Mother to newborn)
• Active immunity – immunity resulting from exposure to a pathogen
(EX: vaccinations) - 20HIVis a human immunodeficiency virus
- 21How does the Immune System respond to HIV?• Attacks helper T cells
• Which results in the B and Killer T cells not coming, which also results to the virus unchecked - 22AIDSare a acquired immune deficiency syndrome
- 23How do you know a person has AIDS?• He/she has HIV
• Has a CD4 cell count
• Has any opportunistic illnesses - 24Opportunistic Illnessis any illness that a person has because they have no immunity
- 25#11) The macrophage enters the body.
2) Then, the helper T-cells call the B-cells.
3) The B-cells make antibodies. - 26#24) The T-cells investigate and call killer T-cells.
5) And then, the killer T-cells kill the pathogens.
6) Then the body calls the suppressor T-cells who stop the whole process. - 27#37) Finally, the antibodies remember the germs.
