positive feedback loop - (ANSWER)-homeostatic mechanism
-response enhances or exaggerates original stimulus
-uncommon in body
-short lived
-examples are contractions in labor by oxytocin and platelet plug formation+ blood clotting
negative feedback loop - (ANSWER)-homeostatic mechanism
-most feedbacks in the body
-response reduces or shuts off original stimulus/ goes in opposite direction
-examples are regulation of body temperature, regulation of blood glucose by insulin
Human life depends on what 5 environmental factors? - (ANSWER)1) water
2) food
3) oxygen
4) heat
5) pressure
1) Water - (ANSWER)-most abundant substance in body
- environment for metabolic processes
-required for transport of substance
-regulation of body temperature
2) Food - (ANSWER)-provides necessary nutrients
-supplies energy
-supplies raw materials for building living tissue
3) Oxygen (gas) - (ANSWER)-one fifth of air

4) Heat - (ANSWER)-heat is a form of energy in out environment
- helps maintain body temperature
- partly controls rate of metabolic reactions
5) Pressure - (ANSWER)-application of force on an object
- atmospheric pressure// important for breathing
-hydrostatic pressure// keeps blood flowing
Identify the parts of a basic homeostatic mechanism. - (ANSWER)1) receptor
2) control center
3) effector
1) receptor - (ANSWER)detects and provides information about the stimuli
2) control center - (ANSWER)decision- maker that maintains the set point
3) effector - (ANSWER)muscle or gland that responds to the control center and causes the necessary
change in the internal enviroment
