25
what does the human body do?
* maintains boundaries • moves • responds to environmental changes * takes in and digests nutrients • carries out metabolism • disposes wastes (Excretion) • reproduce • grow
26
what are our survival needs?
• nutrients • water • oxygen • body temperature • atmospheric pressure
27
homeostasis
homeo = same stasis = standing still -Ability to maintain relatively stable internal conditions even though the outside word is changing ­-internal conditions change and vary, but within narrow limits
28
two types of mechanisms of homeostasis
- negative feedback mechanism | - positive feedback mechanism
29
Negative Feedback Mechanism
net effect of response is to shut off the original stimulus or reduce the intensity Ex. body temperature, heart rate, blood pressure, breathing rate, blood levels of glucose, oxygen, carbon dioxide, minerals (homeostatic imbalance causes illness, disease or death)
30
Positive Feedback Mechanism
net effect increases the original stimulus andpushes the variable farther from the original value Ex. blood clotting, labor
