Necessary Life Functions
Describe the function of maintaining boundaries
keeping internal/external environments separate
(i.e. the skin)
Necessary Life Functions
Describe the movement function
skeletal muscles move food, waste, gas, etc throughout the body
Necessary Life Functions
Describe the responsiveness function
the ability to respond to external and internal stimuli
(i.e using skeletal, smooth and cardiac ms.)
Necessary Life Functions
Describe the digestion function
the ability to break down food into usable forms
food = building blocks & fuel of the body
Necessary Life Functions
Describe the function of metabolism
the sum of all cellular activity/chemical processes
Necessary Life Functions
Describe the function of excretion
the elimination of waste through urine, feces, exhalation and sweat
Necessary Life Functions
Describe the function of reproduction
the production of offspring to maintain the species where cells divide to produce daughter cells
Necessary Life Functions
What is needed within the body in order to reproduce?
cell growth must exceed cell destruction
Necessary Life Functions
Describe the growth function (what is needed)
- hormones
- nutrients from diet
- cell growth must outweigh cell destruction
Define homeostasis
the ability to maintain a stable internal environment
“balance” or “equilibrium”

stress
can be physical, emotional, etc.
Define anatomical position
a universally agreed upon position that allows for universally clear and concise communication
What are the attributes of anatomical position?
- body erect
- head forward
- arms at side
- palms forward
- feet forward and parallel
