Essential Question:
How do major organ systems work
together in living organisms?
Standards:
S7L2d. Explain that tissues, organs, and organ systems serve the needs cells have for oxygen, food, and waste removal.
S7L2e. Explain the purpose of the major organ systems in the human body (i.e., digestion, respiration, reproduction, circulation, excretion, movement, control and coordination, and for protection from disease).
What systems of the body are used when
walking, running, jumping, etc.?

Skeletal System:
Aids in Movement• Bones allow us
to move
• Joints are where
two bones meet
• Bones are connect to
other bones by
ligaments
Skeletal System:
Blood Cell Production
New Blood Cells
are made in the
center of your
bones called the
marrow.
Based on the
diagram to the right,
what would you
guess is the
difference between
Compact Bone and
Spongy Bone?
Compact Bone is very dense and tough.
Spongy Bone is strong, but lightweight.
Skeletal System Analogies
• The Skeletal System is to the Human
Body as ____________ is to
____________.
• How is the Skeletal System like a shield?
• How is the Skeletal System like an
engine?
• How is the Skeletal System like a
factory?
• How is the Skeletal System like the poles
or rope in a tent?
Muscular SystemMuscles of the body that,
together with the Skeletal
System, function to produce
movement.
Types of Muscles
Smooth Muscle–Found inside
organs
–Contracts to move things through the organ
–Involuntary
What does
involuntary
mean?
Types of MusclesStriated (Skeletal) Muscle
–Move your bones and body by
contracting and relaxing
–Attached to bone with tendons
–Voluntary movement
Types of Muscles
Cardiac Muscle
–Found in the
Heart
–Responsible for
pumping blood
through the body
–Involuntary
If your bones allow movement,
and your muscles move your
body, how do we control all of
this movement?
The Nervous
SystemThis system is
responsible for
sending, receiving,
and interpreting
information from all
parts of the body.
The
BrainThe control
center of your
body sends out
and receives
signals to and
from your nerves;
controls organs
Nerves• Sense your external and
internal surroundings
• Communicate
information between
your brain, spinal cord
and muscles
• Coordinate voluntary
and involuntary
movements
• Watch the next Video
• On a scratch sheet of
paper describe what role
these systems play:
•Skeletal system
•Muscular system
•Nervous system
