metabolism ANS >>> sum of al chemical processes
catabolism ANS >>> that break down molecules, releasing energy.
anabolism ANS >>> the process of building up larger molecules
from smaller ones.
3 things that effect growth in the body size ANS >>> 1. increase in
the size of existing cells
2.increase in the number of cells
3.increase in the size of material between the cells
differentiation ANS >>> unspecialized cells become specialized
,reproduction is the formation of new cells for? (2) ANS >>> 1.
tissue growth, repair or replacement
2. production of a new individual
fluid within the cells ANS >>> intracellular fluid
fluid outside the cells ANS >>> extracellular fluid
ECF that fills narrow space between cells of tissues ANS >>>
interstitial fluid
what is the monitored variable called in a feedback loop ANS >>>
controlled condition
what is the stimulus ANS >>> any disruption that changes a
controlled condition
what's the receptor ANS >>> body structure monitoring the
changes of a controlled condition and sends inputs
,what is an afferent pathway-input ANS >>> flows towards the
control centre (nerve impulse or chemical signal)
what is the control centre ANS >>> sets the range of values within
which a controlled condition should be maintained; evaluates
the input it receives from receptors and generates output
commands when they are needed
efferent pathway ANS >>> flow away from control centre to
effector
effector ANS >>> body structure receiving output and brings about
change and produces a response that alters the controlled
condition
negative feedback system ANS >>> reverses a change in a
controlled condition
positive feedback loop ANS >>> strengthens or reinforces a change
in the controlled condition until its interrupted-effector
produces a response that reinforces the initial change-child
birth
, disorder ANS >>> abnormality of a structure or function
disease ANS >>> illness characterized by a recognizable set of signs
and symptoms
symptom ANS >>> subjective changes not visible to the observer
sign ANS >>> objective changes visible to the observer (doctor)
prone ANS >>> body is lying face down
supine ANS >>> body is lying face up
ipsilateral ANS >>> same side
contralateral ANS >>> different sides
superficial ANS >>> towards the surface of the skin
deep ANS >>> away from surface of the skin
