Homeostasis maintenance of an internal state What 2 variables regulate homeostasis? glucose levels, blood pressure What is Type 1 diabetes? the body/beta cells does not PRODUCE insulin What is Type 2 diabetes? the body does not RESPOND to insulin, a cure is exercise What are the 3 parts of a Negative Feedback Loop? sensor, integrator, effector What is threshold the DIFFERENCE where the integrator decides the variation between the action value and the set point is too big What is error sig...

Homeostasis maintanence of an internal state that is distinct from the external environment and is defending against changes Examples of Homeostatic variables temp, pH, fluid volume, glucose, sodium, oxygen tension, Co2 tension Set Point the value we want to maintain Type 1 Diabetes pancreas stops producing insulin Type 2 Diabetes body forms insulin resistance Negative Feedback loop A process in which a change from the normal range of function that opposes or resists that change 3 compo...
