light - Answer- what energy does an xray use
xray - Answer- imaging device that looks at hard tissue/dense structures
CT - Answer- imaging device that creates a cross sectional plane from a number of
different perspectives. Looks at bone
light - Answer- what energy does a CT use
xeon CT - Answer- imaging device that looks at active tissue
xeon CT - Answer- imaging device that requires the patient to inhale a radioactive
gas

DSR - Answer- device that creates a detailed 3D image from a CT scan
light - Answer- what energy does DSR use
DSA - Answer- device that looks at blood vessels
DSA - Answer- device that requires a contrast dye injected into patient to view blood
vessels
light - Answer- what energy does DSA use
PET - Answer- device that shows metabolic processes
PET - Answer- device that requires radioactive isotope injections
PET - Answer- what device is used to determine if a tumor is cancerous or not
M2A - Answer- - a swallowable pill/imaging capsule (has a mini camera on it)
-The pill snaps digital pictures as it passes through the digestive tract
light - Answer- what energy does PET use
ultrasound - Answer- imaging device that uses sound waves to work
ultrasound - Answer- uses high frequency sound waves to look at soft tissue
magnetic - Answer- what energy does MRI use
,magnetic - Answer- what energy does MRS use
MRI - Answer- uses magnetic energy to look at soft tissue; creates a magnetic field
that makes charged ions in the tissue temporarily line up and creates a picture
MRS - Answer- uses magnetic energy to look at COMPOSITION of tissues
MRS - Answer- what is a good device used to look at tumors
structure can dictate function and function can regulate structure - Answer- what is
the relationship of anatomy and physiology
chemical, cellular, tissue, organ, organ system, organismic - Answer- list levels of
organization from lowest to highest
liver - Answer- what is the largest internal organ
skin - Answer- what is the largest external organ
skin - Answer- what is a limiting boundary for the human body
limiting boundary - Answer- this separates things from the outside world
excitability - Answer- ability to detect change within and around the body
conductivity - Answer- ability to send info about the stimuli from one part of the body
to another to create a response
metabolism - Answer- sum total of all chemical reactions that occur in the body
catabolism - Answer- big to small
anabolism - Answer- small to big
growth - Answer- increase in size of existing cells or increase in number of cells
somatic - Answer- what type of cells can reproduce infinitely
gamete - Answer- what type of cells can only reproduce so many times
Nutrients, Oxygen, Water, Normal body temp, atmospheric pressure - Answer- what
are the things we NEED for survival
oxygen - Answer- what is the final electron acceptor for cellular respiration that we
need in order to get energy to function
homeostasis - Answer- condition of a stable internal body environment; dynamic
equilibrium
nervous and endocrine - Answer- what are the two stress regulating systems
, nervous system - Answer- sends fast, electrical messages that react quickly, but
don't last long.
endocrine system - Answer- sends slow, chemical messages that react slowly, but
last long
positive - Answer- feedback system that intensifies the stimulus/original condition
negative - Answer- feedback system that acts to reverse the condition the stimulus
caused and return body to homeostasis
receptor--> (afferent pathway)--> control center-->(efferent pathway)--> effector -
Answer- what are the components to a feedback system
receptor - Answer- detects a stressor and sends the message to the control center
control center - Answer- sends a signal to effector
effector - Answer- uses information given from control center to bring body back to
homeostasis

liquid - Answer- which state of matter? plasma, urine, blood
gas - Answer- which state of matter? air in lungs
no. It's shape can change (doesn't have a definite shape) - Answer- is a muscle a
solid? why or why not
gas - Answer- in which state of matter are molecules the fastest
potential - Answer- creating a bond creates _______ energy into the molecule
energy - Answer- every time we release a phosphate from something, we gain what?
hydrogen, ionic, covalent - Answer- list the three bonds from lowest to highest
energy in the human body
exergonic - Answer- energy released; reactants are higher energy than products
endergoinc - Answer- energy absorbed; reactants are lower energy than products
water - Answer- most abundant inorganic compound in our body
ions - Answer- when salts dissociate in a solution, they form
