What is the function?
What are the structures?
• The function is the job
or action that the
system does.
• The structures are the
parts that work
together to help the
system do its job.
Match the function to the body system
• Circulatory System
• Respiratory System
• Digestive System
• Nervous System
• Musculoskeletal
System
• The job of this system is to carry
gases between the outside air
and your blood.
• This system controls how your
muscles move your bones by
carrying electrical signals from
your brain, to your spinal cord, to
your muscles.
• This system is a transportation
system that carries food and
oxygen to each cell and then
takes away cells’ wastes.
• This system supports the body,
protects organs, makes blood
cells and moves your body parts.
• The job of this system is to break
down food and change it so that
food can enter the blood and get
to cells.
Body systems would not be able to complete their
functions without specific structures .
Examples of structures within body systems:
– The circulatory system needs the heart to pump the blood
throughout the body.
– The respiratory system needs the trachea to carry air from the
larynx to the lungs.
– The digestive system needs teeth to bite and crush food into
smaller pieces that will be easier to swallow, break down and
digest.
– The nervous system needs nerves to carry the electrical signals
from the brain to the muscles.
– The musculoskeletal system needs bones like ribs to protect
organs and muscles like the bicep to help move the arm.
