Transcript Muscle System

Muscle System
Where is the muscle system
located?
• Under your skin
• Everywhere in your
body
What is the role of the muscle
system?
Muscles allow you
to move!
What organs are involved in
your system?
• Your heart is the
only organ that is a
muscle
What are your main functions of
the muscle system?
• Moving bones
• Move the body about
• Muscles are
responsible for
involuntary
movements such as the
diaphragm moving to
help you breathe
What is each organ’s function in
your body system?
• The function of the heart is to bring
nutrients and oxygen to the rest of the
muscles
• It pumps blood constantly and is the
hardest working muscle in your entire
body.
What can go wrong with your body
system?
• Deterioration
• Muscular dystrophy- progressive weakness
and degeneration of the skeletal muscles
that control movement.
• Many other diseases can be obtained and
cause problems in the muscle system.
How do you perform these
functions?

Because of chemical reactions that occur in the body, you produce
very small amounts of electrical energy.
This electrical energy sends a message to your heart and makes it
beat.
There is a patch of cells in the upper right chamber of your heart
called the "pacemaker" that first gets the electrical signal and then
sends the signal on to the rest of the parts of the heart.
There are parts in your brain that can control how FAST or SLOW
your heart beats, but for normal, everyday beating, the pacemaker
keeps your heart going.
Some people have a bad pacemaker and need to get an artificial one.
Muscles are made up of cells that work together to pull, and work
like levers.
When a muscle is working, it is contracting and all the cells are
pulling closer and closer together.
How do people make sure their
muscle system remains healthy?
•
•
•
•
Work out
Eat protein such as steak, chicken, and fish
Take vitamins

What would happen if something
went wrong with the muscle
system?
• If certain muscles stopped working, the
body would not be able to function
correctly.
• If the nerves got cut off, the muscles
wouldn’t receive any messages from the
brain.
• Inactive muscles deteriorate over time.
Could a person survive without
the muscle system?
NO
The heart is the most important muscle in the entire
body you would die with out it. The loss of it would
stop the blood carrying the oxygen and nutrients to the
cells
Why are you an important to the
human body?
The muscle system provides most of
the basic important functions in the
body.
