sinus inversus
left and right reversal of organ placement
anatomical variation
body differs from normal body ex: extra vertebrae or more organs
Metabolism
internal chemical change
responsiveness
ability to react to stimuli
physiological variation
how meds are given depending on sex age diet weight physical activity
homeostasis
the ability to detect change, activate mechanisms that oppose it, and thereby maintain relatively stable internal conditions
negative feedback
senses a change and “negates” or reverses it
self amplifying cycle
greater in the same direction
positive feed back and rapid change
increases for more contractions causing labor to be faster
gradients and flow
heavily effected by osmosis and diffusion
cell theory
all structure and function result from the activity of cells
evolution
the human body is a product of evolution
PET scan
glucose is injected
MRI
alignment and realignment of hydrogen atoms
