 The
circulatory system involves heart,
vessels, blood and the pulmonary and
systematic circuits. It’s also known
cardiovascular system-cardio meaning heart
and vascular relating to blood vessels.
 The functions of the circulatory system are
to transport oxygen and nutrients to parts of
the body and remove waste or toxic products
from the body. The balance of nutrients
keeps the body functioning properly. It also
controls body temperature and to protect
from disease through white blood cells.
 There
are 2 types of circuits in the
circulatory system. The first is the pulmonary
circuit which carries blood from the heart to
the lungs and back again. The other circuit is
the systematic circuit which carries blood
from the heart to the rest of the body and
back again.
 The heart has 4 chambers. The right side
deals with blood with less oxygen. The left
side deals with oxygenated blood (blood with
more oxygen).
Arteries carry blood away from the heart.
 Capillaries are tiny vessels that let blood get to
every small cell.
 Veins bring dark red deoxynated blood back to
the heart.
 Aorta-main blood vessel leaving the heart
 Arterioles-blood vessels that are sub-divisions of
arteries
 Endothelium-internal space of the blood vessels;
in arteries this changes according to the amount
of blood to be transported
 Septum-wall of muscle dividing the left and right
sides of the heart

Valves-opening allowing blood flow in one direction only found in
the heart and veins
Vena Cava-blood vessels transporting deoxynated blood back to
the heart
Red blood cells carry oxygen but they also transport nutrients and
waste products such as carbon dioxide
It is made of hemoglobin which is oxygen chemically attaching
itself to the blood cell.
2 million red blood cells are made and killed every second.
White blood cells help protect the body from diseases,repair
damaged tissue,and destroy bacteria.
There are five types of white blood cells.
Platelets are in charge of clotting blood.
Plasma helps blood to flow easier
Blood is blue before it hits oxygen. When it hits oxygen it turns
red.
