homeostasis

the maintenance of a dynamic equilibrium of internal environment of the body
-body temperature
-acid-base balance
-fluid balance
-hormonal, nutrient, oxygen levels

25

auto regulation (intrinsic regulation)

adjust automatically in response to some environmental changes

26

extrinsic regulation

nervous and endocrine systems adjust the activities of many systems simultaneously

27

negative feedback

a corrective mechanism that opposes or negates a variation from normal limits

28

positive feedback

a mechanism that increases a deviation from normal limits after an initial stimulus

29

what are anatomical "planes"

they reference imaginary "slices" that divide the body

30

sagittal plane

divides left and right parts
-includes the median plane and midsagittal plane
-produces mirror images
