What does pathology mean? - answer study of disease
what is the six levels of structural organization - answer chemical,
cellular, tissue, organ, organ system, organism
The heart is what level of structural organization? - answer organ
A myocyte is what level of structural organization? - answer cellular
Why would a myocyte be cellular? - answer Because cyte= cell
What does catabolism do? - answer breaks down
What does anabolism do? - answer build up
What is metabolism? - answer the chemical processes that occur within
a living organism in order to maintain life.
,What is homeostasis? - answer balance (equilibrium)
What helps maintain homeostasis? - answer nervous system (wires) and

What is intrinsic regulation - answer a small problem in the body
example of intrinsic regulation - answer If your toe becomes to cold it
will be out of homeostasis, but that's just a miner problem and the
body will fix it it's self.
What is extrinsic regulation? - answer a large problem in the body
example of extrinsic regulation - answer If your body gets out of
homeostasis it becomes a big problem. Just like diabetes, for that you
take insulin which brings back homeostasis.
What are the three ways of maintaining homeostasis? - answer
Receptor (sensor), control center (integrator), and effector
, What is the receptor? - answer an organ or cell able to respond to light,
heat, or other external stimulus and transmit a signal to the control
center.
What does the control center do? - answer determines set point,
analyzes information, determines appropriate response
What is the effector? - answer Fixes the problem of the body to bring it
back to homeostasis
What is negative feedback? - answer a system to keep the body in
homeostasis if it ever falls out of homeostasis.
What is postive feedback? - answer child birth or a clotting of the blood
Is blood pressure a negative or positive feedback? - answer Negative
feedback
What happens when the T3/ TA gets out of homeostasis? - answer The
