BLOOD Facts

• Blood flows everywhere
through the human body.
• We cannot live without it.
• The heart pumps blood to all
our body cells, supplying them
with oxygen and food.
• Blood also carries proteins and
cell fragments called platelets
that let blood clot where there
has been an injury.

What makes up our blood?
• RED BLOOD CELLS (Erythrocytes) – The most abundant
cells in our blood; they are produced in the bone marrow and
contain a protein called hemoglobin that carries oxygen to our
cells.
• WHITE BLOOD CELLS (Leukocytes) – They are part of the
immune system and destroy infectious agents called
pathogens.
• PLASMA – This is the yellowish liquid portion of blood that
contains electrolytes, nutrients and vitamins, hormones,
clotting factors, and proteins such as antibodies to fight
infection.
• PLATELETS (Thrombocytes) – The clotting factors that are
carried in the plasma; they clot together in a process called
coagulation to seal a wound and prevent a loss of blood.


Blood Facts
The average adult has about FIVE liters of blood inside of
their body, which makes up 7-8% of their body weight.
Blood is living tissue that carries oxygen and nutrients to
all parts of the body, and carries carbon dioxide and other
waste products back to the lungs, kidneys and liver for
disposal. It also fights against infection and helps heal
wounds, so we can stay healthy.
There are about one billion red blood cells in two to three
drops of blood. For every 600 red blood cells, there are
about 40 platelets and one white cell.

Genetics of Blood Types
• Your blood type is established before you are BORN,
by specific GENES inherited from your parents.

• You inherit one gene from your MOTHER and one
from your FATHER.

• These genes determine your blood type by causing
proteins called AGGLUTINOGENS to exist on the
surface of all of your red blood cells.


What are blood types?
Blood Types
There are 3 alleles or genes for blood
type: A, B, & O. Since we have 2 genes, AA or AO =
there are 6 possible combinations. Type A
BB or BO = Type
B
OO = Type O
AB = Type AB

How common is your blood type?

46.1%

38.8%

Rh Factors
• Scientists sometimes study Rhesus monkeys
to learn more about the human anatomy
because there are certain similarities between
the two species. While studying Rhesus
monkeys, a certain blood protein was
discovered. This protein is also present in the
blood of some people. Other people, however,
do not have the protein.
• The presence of the protein, or lack of it, is
referred to as the Rh (for Rhesus) factor. A+ A-
• If your blood does contain the protein, your
blood is said to be Rh positive (Rh+). If your
B+ B-
blood does not contain the protein, your blood AB+ AB-
is said to be Rh negative (Rh-). O+ O-
