Anticoagulants
Agents that inhibit or delay the clotting process, used to prevent clots from forming in blood vessels of patients predisposed to this condition, and to preserve stored whole blood and blood products. Have no effect on already formed blood clots.
Hemostatics
Drugs, medicines, or blood components that serve to stop bleeding.
Dyscrasia
A morbid condition, usually referring to an imblance of component elements; and abnormal or pathological condition of the blood.
Hemostasis
Arrest of bleeding or circulation.
Septicemia
Presence of pathogenic bacteria in blood, characterized by chills and fever, purpuric pustules, and abscesses. If left untreated, may lead to shock and death.
Autologous
Transfusion prepared from the recipient's own blood.
Homologous
Transfusion prepared from another individual whose blood is compatible with that of the recipient.

Iron-deficiency anemia
Caused by a greater demandon stored iron than can be supplied.

Often as a result of inadequate dietary iron intake or malabsorption of iron.

Most common anemia in world.
Folic Acid deficiency anemia
Caused by insufficient folic acid intake because of poor diet,impaired absorption, prolonged drug therapy or increased requirements as aresult of pregnancy or rapid growth as children.
Tx: Increasingfloic acidin the diet or eliminating contributing causes.
Pernicious Anemia
B12 Deficiency in peripheral RBC's
Found mostly people over 50.
Stomach does not have intrinsic factor, not able to absorb B12
Tx: B12 injections
Hemophilia
Hereditary disorder in which the blood clotting mechanism is impaired.
Found most often in men.
Women are carriers of trait.
Lack factor VIII
(blood clotting factor)
Red blood cells
Normal Range: 4.6-6.5 million
Transport Oxygen
Separation of Blood
Two phases seperates blood from plasma.
Heavier blood goes to the bottom of the cetrufuge vial
Plasma remains at the top
Hematocrit
Blood Test
% of blood cells in a sample of blood
Normal= 45% blood cells, (mostly RBC's)
55% plasma
Low hematocrit indicates anemia
Blood Cells are made from?
Hemopoietic tissue
The process by which bloodcells are made?
Hematopoiesis
Two Types of hemopoietic tissue
In adult: Red bone marrow, found in flat regular bones

lympatic tissue, found in spleen, lymph nodes, and thyroid glands.
White blood cells
Leukocytes
Purpose of white blood cells
to destroy pathogens.
Platelets
Tiniest formed elements in the blood.
Platelet
Is not a whole cell, it is a fragment
Does not contain a nucleus or DNA.
Platelets, life span
Nine days
Thrombocytopenia
Characterized by Petechiae(little, pinpoint hemorrhages,under the skin, and abnormal bleeding episodes)
Macrophages
Stay in liver, spleen, or lymph nodes, wandering macrophages wander through the body particularly abundant under the mucous membranes and under the skin.
Von Willer brand's Disease
Not as fatal a hemophilia, but similar.
Blood Clot
Thrombus
Traveling blood clot
Embolus
Blood clot formation
Thrombosis
Antigen
Genetically determined substance that the body recognizes as foreign.
Type A blood
A antigen on the RBC
Type B blood
B antigen on RBC
Type AB
A&B antigens on RBC's
Type O
O has neither A or B antigen on RBC.
Agglutination
Bloood Clumping
Rh Factor
Antigen the is located on the surface of the RBC

Named after the Rhesis monkey
Blood is composed of two parts
Liquid portion (plasma, pale yellow liquid composed mostly of water.

Formed elements or corpuscles(blood cells)
Serum
Plasma minus the clotting proteins such as fibrinogen
Granulocytes
Neutrophils
Eosinophils
Basophils
Agranulocytes
Lymphocytes
Monocytes
