Let’s go over it… c = spleen a = lymph nodes d = thymus b & E = Peyer’s Patches & Tonsils b = Peyer’s Patches
On the Lymphatic System worksheet… for each specific type of defense tell if it is a structure, cell, or process
Lymphatic System Worksheet What is it? How does it work? Innate Defenses Surface Membrane Barriers Internal Defenses Phagocytes Natural Killer Cells Inflammatory Response Antimicrobial Proteins Fever Adaptive defenses Lymphocytes Macrophages Humoral (Antibody-Mediated) Immune Response Cellular (Cell-Mediated) Immune Response
Antigen Any substance – including toxins, foreign proteins, or bacteria – that, when introduced to the body is recognized as foreign and activates the immune system
Antibody A specialized substance produced by the body that can provide immunity against a specific antigen
Vaccine A substance that includes antigens that stimulate an immune response against a particular pathogen
Additional vaccine info Also known as artificially acquired immunity How it works: dead or weakened (attenuated) pathogen introduced into body body builds up antibodies against that specific pathogen’s antigens (remember those are like protein name tags on cells) antibodies act as ready-defense in case you come into contact w/ that pathogen again
Benefits of vaccines may eliminate or lessen the signs & symptoms of that particular disease weakened antigens can still stimulate antibody production & immunological memory
Overzealous immune response to an otherwise harmless antigen Allergy Overzealous immune response to an otherwise harmless antigen A.k.a. hypersensitivity
Inflammation Response (add this to your lymphatic worksheet) nonspecific response triggered when body tissues are injured 4 parts redness heat swelling pain
