Heart: The organ that pumps the blood
throughout the body
Veins: Transports oxygen deficient blood to
heart and lungs
Arteries: Transports oxygen rich blood
throughout the body
Blood: The fluid consisting of plasma, blood
cells, and platelets that is circulated by the
heart carrying oxygen and nutrients to and
waste materials away from all body tissues.

Right Coronary and Left Coronary: The coronary arteries are the
network of blood vessels that carry oxygen- and nutrient-rich blood
to the cardiac muscle tissue.
Superior Vena Cava: Veins from the head and upper body feed into
the superior vena cava, which empties into the right atrium of the
heart
Inferior Vena Cava: Veins from the legs and lower torso feed into the
inferior vena cava, which empties into the right atrium of the heart
Aorta: The largest single blood vessel in the body. It is approximately
the diameter of your thumb. This vessel carries oxygen-rich blood
from the left ventricle to the various parts of the body
Pulmonary Artery: The vessel transporting de-oxygenated blood from
the right ventricle to the lungs
Pulmonary Vein: The vessel transporting oxygen-rich blood from the
lungs to the left atrium
Atrium: The right atrium receives de-oxygenated blood from the
body through the superior vena cava (head and upper body) and
inferior vena cava (legs and lower torso) and pumps to the ventricle
 Ventricle: The right ventricle receives de-oxygenated blood as the
right atrium contracts. Pumps to the pulmonary valve which allows
the blood to flow into the pulmonary artery toward the lungs
 Papillary Muscles: The papillary muscles attach to the lower portion
of the interior wall of the ventricles
 Chordae Tendineae: The chordae tendineae are tendons linking
the papillary muscles to the tricuspid valve in the right ventricle and
the mitral valve in the left ventricle

Tricuspid Valve: The tricuspid valve separates the right atrium
from the right ventricle. It opens to allow the de-oxygenated
blood collected in the right atrium to flow into the right ventricle
 Mitral Valve: The mitral valve separates the left atrium from the
left ventricle. It opens to allow the oxygenated blood collected
in the left atrium to flow into the left ventricle
 Pulmonary Valve: The pulmonary valve separates the right
ventricle from the pulmonary artery. As the ventricles contract, it
opens to allow the de-oxygenated blood collected in the right
ventricle to flow to the lungs
 Aortic Valve: The aortic valve separates the left ventricle from
the aorta. As the ventricles contract, it opens to allow the
oxygenated blood collected in the left ventricle to flow
throughout the body

The blood carries oxygen and essential
nutrients to all of the living cells in the
body, and also carries waste products
to systems that eliminate them. Most of
the blood is made up of a watery,
protein-laden fluid called plasma. A
little less than half of this blood volume
is composed of red and white blood
cells, and other solid elements called
platelets.
 Platelets are responsible for
coagulation of blood at the point of
an injury to a blood vessel. Without
platelets, our blood would not be able
to clot and hemorrhaging or
uncontrolled bleeding would result.

With a partner, measure your pulse and
heart rate.
 Find your pulse either in your neck or your
wrist.
 For 15 seconds, count your heartbeats
and multiply that number by four

The average adult has between 5 to 6 liters of
blood or blood volume.
Hemophilia is a genetic condition, which results
in individuals with no ability to clot. Also called
bleeders, these individuals must periodically
administer a clotting factor to their blood to
prevent the constant bleeding, which occurs.
A systolic blood pressure of 120 millimeters of
mercury is considered right in the middle of the
range of normal blood pressures, as is a
diastolic pressure of eighty. In common terms,
this normal measurement would be stated as
"120 over 80".
