Cells to System Test Review Powered By Docstoc
					The following
information is from
video information
and could most likely
appear on your test.
   1. Nutrients



   2. Oxygen




   3. Get rid of waste
   Heart
   In the cardiovascular system the vascular part is referring to the
    blood vessels.
   These include the arteries and veins.
   Arteries take the blood away from the heart and Veins bring the
    blood back to the heart.
   Human blood is never BLUE!!!!
   Check out this website if you are still not convinced:
   http://www.biology-online.org/biology-forum/about763.html

   Remember it is bright red with oxygen and a deep maroon-type
    color when deoxygenated. See the difference in the colors of the
    flowers—the one on the left is bright-(oxygenated) and the one on
    the right (de-oxygnated) –this may give you an idea of the color
    difference.
 Remember the parts;
Heart, arteries, veins,
and blood
   Your heart is a non-stop pump--Cool huh?!
   It can be as large as your wrist because so
    much blood goes from the heart out to your
    body parts.
  Some are so small that red blood cells have to
   go through them single file!!!
What looks like a pink malt ball is
the red blood cell.
   Arteries take blood Away from the heart.
   For veins you have to remember that they
    bring the blood back to the heart.
   In pictures the arteries appear red and the
    veins appear blue.
   This includes your brain, spinal cord and all the
    nerves. Your brain
   sends messages to
   muscles and other
   body areas and any
   sensations from your
   body goes to your
   brain for it to interpret
   what the sensation
   means. (pain, danger,
   comforting)
   This is your largest organ. You have many
    parts to your skin—it protects you from the
    outside environment
  This is how oxygen
gets to your lungs and
cells and then the by
product of carbon
dioxide is removed.
   You know this is the framework to your body
    and that you would be a basic blob without it.
    It also allows you to move.
   Remember that tendons hold muscles to bones




Ligaments hold bone to bone.
   This removes the
   liquid waste from
   our body. It also
   keeps what we
   need.
   Nutrients must be broken
   down so our body can use
   them. The system is one
   long tube from our mouth
   to our anus.
   The total length of your
   intestines is about 27 feet.
   The liver is included in
   this system and is your
   largest internal organ.
   Our body can ABSORB the required nutrients.
    This helps to keep us healthy.
   Used to keep the human species around.
    Generally requires a male and a female.
   Muscles help you move, give you shape and
    form. Can be exercised to become larger and
    stronger.
   Keeps our body healthy—like little soldiers
    fighting for our health.
   Mostly glands and organs
   that supply the white
   blood cells or hormones
   to help fight or trap
   the infections and bacteria
   that may threaten our
   bodies.
   Lymph nodes-these filter and remove harmful
    substances from your blood. You have lots!!!
   Bone marrow which makes blood cells-red and
    white. White is a protector and red carries your
    oxygen to cells .
   It prepares the “T” cells
   These go around your body
   and look for bad cell
   growth and destroy it.
   This helps filter the blood and remove
    unwanted elements—even old worn out red
    blood cells.
   A complicated system of glands and hormones
    that keep you working correctly. If this
    becomes upset or diseased your health is not as
    good.
   Each system has a specific job and organs to
    help do these jobs.
   We went from cells to tissues, tissues to organs,
    organs to organ or body systems, and then the
    body systems make the organism.
   Study well.
