HBS - lymphatic & immune system
Vocab / Concept | Definition / Explanation |
pathogen/antigen | a disease-causing organism |
prions | (non-living proteins) infect through contamination, meds slow it down |
viruses | (non-living) infect through contact, or bodily fluids. hosts cells are destroyed, vaccine builds acquired immunity |
bacteria | (living) infect through orifice, wounds, contamination, contact. meds = antibiotics, hygiene & vaccinations |
orifice | nose, eyes mouth |
protists | (living) infects through contaminated feces, meds = antiprotozoal |
fungi | (living) infects when spores of fungi inhaled or land on host. meds = antifungals |
helminths | (living worms) contamination or through infected insect. meds = deworming |
mucus | this traps the pathogens in our body and is either swallowed to be killed through stomach acid or blew out the orifices |
epidermis | top layer of skin - provides barrier - makes new skin - provides color |
dermis | middle layer - contains collagen - makes oil/sweat - contains blood vessels/nerve endings |
subcutaneous fatty tissue | bottom layer of skin - fat/cushion - bones - helps regulate body temp |
sepsis | the body’s immune system overreacts to an infection causing inflammation |
severe sepsis | organs in the body begin to malfunction, blood pressure is low, and inflammation continues |
septic shock | extremely low blood pressure that does not respond to IV fluids |
lymph nodes | small lumps of tissues that contain wbc's to fight infections |
lymph | fluid in the body made mainly from wbc's |
lymphatic system | maintains fluids, absorbs fats, protects from pathogens, transports/removes waste from fluid |
immune system | use organs from other body systems to protect body, anything this system doesn't recognize; it fights it |
platelets | aid in blood clotting |
red blood cells | hemoglobin rich, transport oxygen through body |
white blood cells | active in immune response, lymphocytes, monocytes, etc |
innate immunity | any defense mechanisms that you are born with |
acquired immunity | defense mechanisms that are acquired throughout life |
b-cells | matures in bone marrow - produces antibodies |
antibodies | produced by b-cells to impair pathogens |
prodromal | early signs of symptoms |
convalesce | gradual recovery after health had decreased |
t-cells | type of wbc that recognizes and attacks pathogens |
virus attacking host cell | AEURAMR - assembly, entry, unleash, replicate, assembly, maturation, release |
