Blood functions to pick up and deliver nutrients
and take away waste.
Delivery jobs
Deliver digested nutrients from fats, proteins, and
carbohydrates to all body cells.
Delivers oxygen to all body cells.
Delivers chemical messengers to some body
cells.
Delivers water, minerals and vitamins to all body
cells.

Pick up jobs
Pick up carbon dioxide waste from cells
and carry it to the lungs.
Pick up chemical waste from cells and
carry it to the kidneys.
Pick up excess body heat and carry it to
the skin. (Red flush from exercise)
Blood helps in fighting diseases and help
to stop bleeding.
Some animals have NO blood. (sponges,
jellyfish, flatworms)
Chapter 12.2 Notes
• Plasma is the
nonliving, yellow
liquid part of blood.
92% water, 8%
proteins, nutrients,
salt.
• Bone marrow is the
soft center part of
the bone. Make red
and white blood
cells.

Red blood cells
Carry oxygen
5 million in one drop
of blood
Live 120 days
No nucleus
Make up the majority
of your blood
Hemoglobin is a protein in red blood cells that joins with oxygen
and gives the red cells their color. Contain Iron.
Anemia is a condition in which there are too few red blood cells
in the blood. The person feels weak, tired and short of breath.

White Blood Cells
Destroy harmful microbes
Remove dead cells
Make proteins that help
prevent disease
Have nucleus
Bigger than Red Blood
Cells
8000 in one drop of blood
Live 10 Days
Made in spleen, thymus and
tonsils.
White blood cell
•
Leukemia is a blood
cancer in which the
number of white blood
cells increase at an
abnormal rate.
1. May have 100 000 white
blood cells (during
infection 30 000)
2. White blood cells count
doesn’t return to normal
3. White blood cells can not
perform jobs
Dark purple cells are white
blood cells.

Platelets
Aid in forming
blood clots.
Not complete
cells.
Smaller than
red blood cells
250 000
platelets in a
drop of blood
Live 5 days
Arrows point to platelets
Hemophilia is a disease in which a persons blood won’t clot.
Genetic disease. Lack the clotting chemical in blood.
Chapter 12.3 Notes
• 4 main blood types= A, B, AB, O
• Difference is due to proteins found on red
blood cells and in blood plasma.
• Types A & B blood cells are different.
• Type AB red cell proteins are the same as
both type A & B, has NO Plasma proteins.
• Type O has plasma proteins like types A &
B.
• If different blood types are mixed large
clumps of blood form and can not pass
through capillaries. Can cause blocked
vessels in the heart, brain, or lungs. Death
can occur.

•
Which blood types can be given to:
Type A blood? A or AB
Type B blood? B or AB
Type AB blood? AB
Type O blood? A, B, AB, O
Chapter 12.4 Notes
• Immune system is made of proteins, cells
and tissues that identify and defend the
body against foreign chemicals and
organisms.
• Teardrops, mucus and skin are part of the
immune system.
• Antibodies are chemicals that help destroy
bacteria or viruses. (made by body).
• Antigens are foreign substances, usually
proteins, that invade the body and cause
diseases (Bacteria or viruses)
• When you are sick
your white blood cells
attach to the bacteria
and break it open.
Once the bacteria is
open it dies. Each
different type of virus
or bacterium that
enters the body has a
different antigen
shape. Your immune
system “remembers”
the shapes.
• DPT shots protect against diphtheria,
pertussia, tetanus. (Vaccination)
• Immunity is the ability of a person who
once had a disease to be protected from
getting the same disease again.
• AIDS- Acquired Immune Deficiency
Syndrome-is a disease of the immune
system. Caused by a virus found in body
fluids, such as blood and semen. Destroy
white blood cells.
4 ways a virus can be passed
1. Sexual intercourse
2. Sharing needles
3. Pregnant woman to unborn child
4. Blood transfusion
39.4 million infected w/HIV worldwide, more
than 2/3 are in Africa!
