Question

what does the human body do?

Answer 1

* maintains boundaries • moves • responds to environmental changes * takes in and digests nutrients • carries out metabolism • disposes wastes (Excretion) • reproduce • grow

Answer 2

• nutrients • water • oxygen • body temperature • atmospheric pressure

Answer 3

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

Answer 4

- negative feedback mechanism | - positive feedback mechanism

Answer 5

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)

Answer 6

net effect increases the original stimulus andpushes the variable farther from the original value Ex. blood clotting, labor
