○ Must remain close to 98.6 FGlucose levels
○ If too high or too low, can cause coma or death
Pathogen free○ Keep all disease-causing agents out of your
body

Systems involved
All systems really involved Systems to be reviewed in this unit:
IntegumentaryImmuneLymphaticExcretory

Integumentary System
Your body’s coveringsIncludes
○ all layers of your skin○ Hair follicles, hair○ nails

Immune System
Keeps you free of diseaseWhite blood cellsBone marrow
All designed to kill anything that is not recognized as being a part of you or is recognized as being bad for you

Lymphatic System
Prevents buildup of fluids from collecting in tissues
Produce antibodies to act against pathogens

Excretory System
Monitors fluid levels in blood stream Removes any nitrogenous waste and
excess water from blood stream

Disruptions of Homeostasis
Burns Diabetes

Burns
Degrees1st- usually mild, with redness on skin2nd- bubbling of skin3rd- complete peeling/removal of skin
Anytime damage done to skin, becomes nearly impossible to prevent pathogens from entering and water from leavingAlso makes thermoregulation VERY difficult

Diabetes
Type 1- body cannot make insulin Type 2- body cannot recognize insulin’s
signal and follow its instructions
Body does not have the ability to react to changes in blood sugar levelsCan result in rapid death if not managed
properly
