Body Systems
How is your body like a
machine?
Let’s think back….
• Why do all
the body
systems
work
together?
To maintain
homeostasis!
SKELETAL SYSTEM
•What are the functions?
-produces red and white blood cells
-movement
-structural support
-provide minerals
•What other systems are involved?
-muscular
-immune
MUSCULAR SYSTEM
•What are the functions?
-movement (body parts,
digestion, circulation)
• What other systems
does it involve?
-Skeletal
-Nervous
-Digestive
-Circulatory
Muscle Types
SKELETAL
SMOOTH
CARDIAC
How do you bend your elbow?
To what are muscles
attached?
• The bicep muscle
contracts, causing the
elbow to bend.
• The tricep muscle
contracts, causing the
elbow to straighten.
This works similar to what
simple machine?
LYMPHATIC SYSTEM
• What are the
functions?
•protect body
from disease
•contains white
blood cells,
antibodies and
lymph

DIGESTIVE
•What are the functions?
•to break down food into
smaller particles with the
help of enzymes so it can
be absorbed and used by
cells.
