BLOOD DISORDERS
ANEMIA
o Iron-Deficiency Anemia (most common)
o Aplastic Anemia - bone marrow does not produce enough RBC
o Hemorrhagic anemia - due to extreme blood loss
o Pernicious anemia - B12 deficiency
o Sickle Cell Anemia (genetic)
LEUKEMIA
o Type of cancer
o Overproduction of immature white blood cells
o They take the place of RBCs
o Treatable with bone marrow transplants, chemothemotherapy, radiation
INFECTIOUS MONONUCLEOSIS
Sometimes called "mono" or "the kissing disease," is an infection usually caused by the EpsteinBarr virus (EBV).
EBV is very common, and many people have been exposed to the virus at some time in
childhood.
BLOOD POISONING - SEPTICEMIA
o An infection enters the blood stream, can be deadly
o Treated with antibiotics
THROMBOCYTOPENIA
o Low production of Platelets, Causing bleeding or bruising
The Genetics of Sickle Cell Anemia
Genetic Disorder, Abnormally shaped blood cells
Parents can be carriers (asymptomatic)
Sickle Cell Anemia is actually codominant
AA = normal
Aa = sickle cell trait (few symptoms)
aa = sickle cell anemia
Complications
Pain
Lethargy
Lifelong
anemia (low
red blood
count)
Organ failure
Stroke
The Genetics of Hemophilia
Hemophilia is sex-linked, meaning it is carried on the X chromosome.
Females can be normal, carriers, or have the disease
Males can be normal or have the disease, but they cannot be carriers
When a female with hemophilia has children, she will pass the gene to each of her
sons.
