represents the atoms and molecules that make up
Chemical level
cells (Consists of Atomic level and molecular level)
Cellular level represents the basic unit of all living things
Tissue level a group of cells with similar or common function
Organ level a group of tissues with similar or common function
Organ system level a group of organs with similar or common function
the entire body consisting of the various organ
Organismic level
systems.
controls body temperature & protects body from

ingestion, breakdown and absorption of food &
Digestive System
elimination of indigestible wastes
filtration of blood to maintain proper water and salt
Urinary System
balance and to eliminate waste products
produces sex cells and hormones related to
Reproductive System
reproduction
condition in which body's internal environment
homeostasis
remains within certain narrow physiological limits
adjustment of physiological system to maintain
homeostatic regulation
homeostasis
monitors change in controlled condition (stimulus)
receptor
and sends input to control center
control (integration) receives input from receptor & determines
center appropriate response
cell or organ that receives information (output) from
effector
control center and produces a response (effect)
stimulus -> receptor -> input (afferent pathway) ->
interactions of a
control center -> output (efferent pathway) ->
feedback system
response
the response by the effector to the initial change is
to further exaggerate the change. Example in labor
positive feedback
contractions, the contraction of the uterus forces
the baby towards the birth canal, which
places pressure on the ...
cervix; the pressure of
the baby against the
cervix causes uterine
contraction, etc.
the response by the effector to the initial change is
to counter or reduce that change, thus bringing the
Negative feedback
system back to its "normal" state. Example When
blood sugar level rises, the pancreas secretes
