Circulatory System
Some scientist say
that you can wrap
your blood vessels
around the
equator twice!

The Job
The Circulatory System is a
transport system used to take
materials to different places.
The Thick-Walled Blood Vessel
Arteries – A blood vessel that
carries oxygenated blood
away from the heart
The oxygenated blood are then
transferred into capillaries.
The main artery is the aorta
which is in the area of your
neck, people commit suicide
by cutting there aorta.
The Thinnest Blood Vessel
Capillaries-Blood
Vessels that gives the
oxygen and nutrients
to the cells
The cells then release
waste like carbon
dioxide into the blood.
Capillaries are so tiny
that only one blood
cell can fit through at
time
The Thinner-Walled Blood Vessel
Veins- branching blood
vessels
Veins carry blood with
carbon dioxide back to
the heart through the
pulmonary vein.
Red Blood Cell
Red Blood Cell – Cells
in your blood that
pick up carbon
dioxide from your
cells to your lungs.
Red blood cells look
red because of a
protein,
hemoglobin. Red
blood cells are a
disk-like shape.
White Blood Cells
White Blood Cells –
blood cells that
fight germs
Without white blood
cells you would be
sick almost all the
time. White blood
cells release
antibodies if you are
familiar with the
germs to kill them.
Platelets
Platelets-blood cells
that heal wounds
Platelets clog the wound
and seals it.
Platelets are produced
in the bone marrow.
Protein in platelets
allow them to stick to
blood vessel's wall
and to each other.
Plasma
Plasma- the liquid
element of blood
Plasma drops off a variety of
substances to the cells and
picks up waste. Plasma
contained about 90% water
and 10% proteins. Plasma is
usually straw colored (left), or
a grayish cloudy color
depending on your diet and
health.
The Relationship Between the
Other Body Systems
The Circulatory
System helps out the
Respiratory System
by taking oxygen from
the lungs and
dropping off carbon
dioxide.
The
circulatory
system also helps the
digestive system by
transporting the
nutrients to the cells.
Keep Your Circulatory System
Healthy!!!
Eat a variety of foods, but not
too much junk food to help
your cells get the nutrients
they need. Exercising is also
excellent because your heart
beats faster and it gets
stronger, after all it is a
muscle. Last, but not least
DON'T SMOKE! The bad air
that you breathe in might get
picked up by the blood cells
and get circulated around the
body
