Help with clotting
Produced in red bone marrow
Live about 10 days
Clotting process: platelets stick to
damaged tissue and to each other.
Group together to control blood loss
from blood vessel.

Water
Protein
Salts

Blood Typing
Key Terms
• Antigens: foreign object, pathogen
• Antibodies: proteins secreted by lymphocytes
• Antibodies bond with antigens = lock and key phenomenon
Antigen = lock
antibody = key
Blood Type Inherited
• Each person inherits 2 genes.
• Dominant genes
• Are A and B
• Shown as “I”
• EX:
• Recessive genes
•O
• Shown as “i”
• Ex:
Punnett Square
4 Blood Types
• Blood type is determined by antigens on the surface of RBC
•A
• Only A antigens
•B
• Only B antigens
• AB
• Both A and B antigens
•O
• Neither A or B antigens
• Your immune system has a tolerance against it own antigens.
(you like your own antigens)
EX: Antigen
A
type
A blood. It will NOT form anti-A antibodies.
Blood Type

Antibodies in Plasma

Transfusions
• Need to mix serum of the patient with the blood cells of the donor.
• If Type A gets matched with Type B then antibodies will clump
together
• If this test is not done hemolysis (rupture of blood cells) can occur
Blood
• Type O Blood
• Universal donor
• Because it lacks A and B antigens
• Type AB Blood
• Universal recipients because they lack anti-A and anti-B antibodies.
• (they won’t attack new blood coming in)
Rh Factor Antigen
• Found in RBC
• Rh- : people who do not have antigens on RBC
• Rh+ : people who do have the antigen on RBC
• About 85% of Americans are Rh+
• If RH + blood is given to Rh- then the body thinks it is an invading
pathogen and starts to form antibodies for the lock and key
Rh Factor Health Concerns
• When an Rh- mother delivers an Rh+ baby, some of the baby’s blood
may contact the blood of the mother
• The mother’s blood then forms antibodies against Rh+ RBC
• If the mother has another Rh+ pregnancy the antibodies will attack
the baby’s blood causing erythroblastosis fetalis.

Health Matters of the
Circulatory System
Anemia –
most common blood disorder
• Etiology:
• Inadequate amount of hemoglobin, RBC or both
• S/S: shortness of breath, pallor (pale), rapid heart rate.
• TX: dietary supplements, blood replacement.
Hemophilia
• Etiology: rare sex linked genetic blood disease in which the blood is
missing a clotting factor.
• S/S: prolonged or uncontrolled bleeding
• TX: giving plasma that contains the missing clotting factor, no cure
Acquired immunodeficiency syndrome (AIDS)
• Etiology: dysfunction of the immune system caused by a virus. Virus
will cause DNA to become infected damaging WBC.
• HIV is transmitted through exchange of body fluids.
• S/S: may not show for 6-10 years: fatigue, weakness, painful joints,
diarrhea.
• TX: no cure, experimental medicines.
Leukemia
(blood cancer)
• Etiology: abnormal
malignant increase in the
number and longevity of
WBC. WBC are immature
and less effective in fighting
disease
• S/S: bleeding gums, anemia
• TX: radiation,
chemotherapy, bone
marrow transplantation
Elephantiasis
• massive accumulation of lymphatic
fluid in body tissues, causing
abnormally large growth of tissue.
• Etiology: caused by obstruction of the
lymph vessels by tiny worms (filariae)
that are common in tropic and
subtropic areas.
• S/S: fever, chills and ulcer formation
• TX: no cure, oral medications and
mosquito control measures.
Sickle cell anemia
• Etiology: genetic condition that
results in malformed RBC
• The “sickled” cells are more
fragile and cause pain as vessels
are blocked and less oxygen is
delivered.
• S/S: sometimes no symptoms,
may cause death
• TX: no cure
Allergy
• Etiology: hypersensitive response by
the immune system to an outside
substance which becomes an allergen.
• Allergens cause antibodies to be
produced. EX: pollen, dog/cat fur,
feathers.
• S/S: inflammation of the respiratory,
GI and integumentary systems, may
become life threatening.
• TX: drugs
Autoimmune Diseases
• Etiology: conditions in which the immune system of the body turns against itself.
• EX:
• Systemic lupus erythematosus: affects connective tissue, kidneys, lungs and heart
• Hashimoto’s disease: destruction of the thyroid
• Myasthenia gravis: affects the nerves and causes paralysis
TX: immunosuppressive drugs and steroids to relieve inflammation.
Erythroblastisis fetalis
• Etiology: Antibodies from an Rh negative
mother may enter the blood stream of her
unborn Rh positive infant, damaging the red
blood cells (RBCs). The infant responds by
increasing RBC production and sending out
immature RBCs that still have nuclei.
• S/S: baby may have brain damage
• TX: intrauterine blood transfusion
Hodgkin’s disease
• Etiology: cancer of the lymph system that usually appears in people
between the ages of 15-30.
• S/S: painless enlargements of the lymph nodes, itching, weight loss,
fever, difficulty swallowing.
• TX: chemotherapy or radiation of the lymph nodes.
Splenomegaly
• Etiology: enlargement of
the spleen caused by an
acute infection such as
scarlet fever
• S/S: symptoms are similar
to leukemia and anemia.
• TX: may require removal of
spleen
Thrombosis
• Etiology: condition in which a blood clot (thrombosis) forms in the vessels. Clot
slows the flow of blood to tissues
• Embolus: when the clot breaks away, it could lodge in a blood vessels and cause
tissue death
• S/S: pain in the area of the clot because of lack of oxygen
• TX: elevation, anticoagulants, may have surgery to remove clot.
