Human Body Systems
Organization of The Body


The eleven organ systems of the human
body work together to maintain
homeostasis
Homeostasis – process which organisms
maintain a relatively stable internal
environment



Brain, Spinal cord, peripheral nerves
Function: Coordinates the body’s
response to changes in its internal and
external environments
1) What is the function of the
nervous system?
A.
B.
C.
To respond to stimuli found inside
and outside the body.
To pass oxygen to the cells.
To exchange oxygen from the
lungs to the blood.
2) The nervous system includes
which organs
A.

Brain, Spinal Chord, Heart
Brain, Spinal Chord, Peripheral nerves
Brain, Spinal chord, chloroplast

lymph nodes, lymph vessels
Helps protect the body from disease;
collects fluid lost from blood vessels and
returns the fluid to the circulatory
system.
