•There
are 5-6 liters in a grown male
•It is about 8% of your body weight
AKA: Red Blood Cells
 Donut shaped! (But there’s not a hole in
the middle, it’s just flattened out)
 Makes up 45% of all blood
 Main job: transport oxygen from the
lungs to the rest of the body
 Only last for 4 months, then they are
removed from the body by the liver
 Contains hemoglobin


Protein on the erythrocyte
that holds the oxygen
molecule
› There are 250 million
hemoglobin molecules on
EACH erythrocyte…
› Each hemoglobin molecule
can carry 4 oxygen
molecules…
 250 million x 4 = 1 billion
oxygen molecules can be
carried by 1 erythrocyte


AKA: White Blood Cells
Makes up 1% of all blood
Protects body, fights infection
Can leave the blood vessels to hunt down
and destroy infections!
Leukocyte levels can be measured to
determine if person is sick
If you are sick (fighting infection), your
body makes a lot of leukocytes to win the
fight… so more leukocytes = probable
infection
Makes up 1% of all blood
 Pieces of cells
 Clots bleeding

Makes up 53% of all blood
 Fluid part of blood

› Mostly water
Blood cell formation (making blood cells)
 Happens in:

› the ends of long bones in red bone marrow
› flat bones like skull and pelvis
› ribs & sternum
Blood Transfusion – the transfer of blood from one
person to another
Why would someone need to receive blood from
another person?
Certain
diseases like Sickle Cell Anemia
Cancer, for example Leukemia
Surgeries like organ transplant or Open-Heart Surgery
 Open-Heart surgeries can require up to 10 pints of
blood
There are 4 blood
types:
A = 40%
B = 11%
AB = 5%
O = 44%

• Antigens are little proteins on the outside of red blood cells
• Antibodies are made for any antigens you don’t have on
your red blood cells
• If you put blood in your body, and you have already made
antibodies for those antigens, your body will start attacking
• This attacking can lead to blood clots, which can cause
heart attacks and strokes
