A antigen

Two blood group systems that are determined in routine blood typing are:

ABO and Rh

a clinical sign indicating that the number of circulating RBC's and/or the amount of circulating hemoglobin is below normal. This results in an inability to transport an adequate amount of oxygen to tissues.

Anemia

a serious disorder that results when the bone marrow no longer producing RBC's, so the number of RBC's and the amount of hemoglobin both decrease.

Aplastic anemia

Anti-B serum contains antibody B that bonds only to _______________; (agglutination = presence of_______________)

B antigen

granulocytes. are the least common of the WBC's in a normal blood smear making up only 0-1% of the total leukocytes. The cytoplasm contains many large purple to dark blue granules that visually obscure the view of the S-shaped nucleus.

Blood typing is performed to determine compatibility for blood transfusions. Severe adverse reactions, even death, can result if an incompatible blood transfusion is performed. It is important to understand that the donor's plasma is removed from the blood, so only the RBC's are transfused into the patient who is receiving the blood transfusion.

Dehydration

1. Start here a. The cell's nucleus is multi-lobed. Go to 2. b. The cell's nucleus does not consist of lobes. Go to 3. c. The cell's nucleus is obscured by large dark blue granules, giving the cell the appearance of a blackberry: Basophil. 2. The cell's cytoplasm is pink in color. a. Cell's cytoplasm is peppered with small light pink granules; nucleus has 3-5 distinct lobes (polymorphonuclear): Neutrophil. b. Cell's cytoplasm is filled with large red granules; nucleus is bi- lobed: Eosinophil. 3. The cell's cytoplasm is a silvery-blue color. a. Cell contains a round nucleus that occupies almost the entire interior of the cell: Lymphocyte. b. Cell has a horse-shoe shaped nucleus and the cell is about twice the size of a RBC: Monocyte.

Dichotomous key for identifying leukocytes (WBCs).

granulocytes. account for only 2-4% of the total leukocytes. They contain a bi-lobed nucleus and large, orange to reddish colored granules fill the cytoplasm.

Eosinophils

are anucleate, biconcave discs containing hemoglobin, which reversibly binds oxygen, CO2 and H+, and therefore has the function of transporting of blood gases.

Erythrocytes or red blood cells

constitute the vast majority of formed elements (99.9%). They are pinkish, biconcave, anucleate cells that are about 7-8 micrometers in diameter.

Erythrocytes or red blood cells (RBC's)

make up about 45% of whole blood. Composed of Erythrocytes or red blood cells, Leukocytes or white blood cells, and Platelets or thrombocytes.

Formed elements

the percentage of a whole blood sample accounted for by erythrocytes or RBC's.

Hematocrit or the packed cell volume (PCV)

a reduced number of RBC's and reduced amount of hemoglobin due to bleeding.

Hemorrhagic anemia

a reduction in the number and size of RBC's and decreased hemoglobin due to a lack of iron.

Iron deficiency anemia

are nuclei-containing cells of the immune system. Five different types of these cells can be identified when blood is viewed microscopically.

Leukocytes or white blood cells

increases the production of the hormone erythropoietin, which stimulates RBC production.

Living at high altitude

agranulocytes are the second most prevalent WBC's accounting for 20-30% of the total number, so you will see many of them in a blood smear. They can be large or small depending upon their state of maturation. The small ones are the most prevalent and are identified by a round nucleus that fills almost the entire cell; often only a small sliver of cytoplasm is present between the nucleus and membrane.

Lymphocytes

agranulocytes are the largest of the WBC's and compose 3-8% of the circulating leukocytes. They are about double the size of a RBC. The classic one of these consists of a nucleus that has a large, deep indentation, which makes the nucleus have a horse-shoe shape. A large lymphocyte and one of these can be easily confused.

Monocytes

granulocytes. are the most numerous of the white blood cells accounting for 60-70% of the total number. They are identified by their nuclei consisting of 3-5 lobes connected by slender strands and small light-pink granules in the cytoplasm. The multi-lobed nucleus is the reason why this cell is also called the polymorphonuclear (poly=many and morpho=structure) leukocyte.

Neutrophils or polymorphonuclear leukocytes

a disorder in which there is a reduced number of RBC's in the circulation due to a lack of vitamin B12. The deficiency of B12 causes decreased DNA synthesis resulting in RBC's that are abnormally large. Because this anemia results in the production of large cells, it is classified as a megaloblastic anemia.

Pernicious anemia

a straw-colored clear solution that makes up about 55% of whole blood. It mostly consists of water, but also contains a variety of dissolved and suspended chemical substances, from small blood gas molecules like carbon dioxide and oxygen to larger molecules like complex proteins. is the liquid component of blood, which accumulates at the top of a glass tube after centrifugation.

Plasma

are cell fragments that appear as tiny purple bits scattered among the red and white blood cells. They are involved in hemostasis (stopping of blood flow).

Platelets or thrombocytes

are cellular fragments involved in blood platelet plug formation and hemostasis (blood clotting).

Platelets or thrombocytes

a general term that refers to an elevated amount of RBC's relative to the entire sample of blood (increased hematocrit).

Polycythemia

a disease of the bone marrow that results in an increased number of RBC's in circulation due to overproduction of cells by the bone marrow.

Polycythemia vera

If a person has the Rh antigen on the RBC membrane, he/she is Rh+. If a person lacks the Rh antigen on the RBC membranes, he/she is Rh-. In the Rh system, a person who is Rh- doesn't produce the Rh antibody until the person is exposed to the Rh antigen. This production of antibody after exposure to antigen makes the Rh system different from the ABO system.

Rh Blood Group

Anti-Rh serum contains antibody Rh that bonds only to _______________; (agglutination = presence of_______________)

Rh antigen

Rh antigen = present Antibody = None

Rh+

Rh antigen = absent Antibody = None until exposed to Rh antigen

Rh-

White blood cells lacking visible granules when viewed with the light microscope

agranulocytes

proteins produced by immune cells that are dissolved in body fluids such as blood plasma. When an antibody encounters an antigen, the resulting immune reaction includes the attachment of ________________ to the cell's antigen, which "tags" the cell for destruction by macrophages. In addition, one _____________ can attach to more than one RBC resulting in the formation of a cluster of RBC's attached to each other by antibodies; this is known as clumping or agglutination.

antibody(ies)

A person's blood type is determined by the presence or absence of genetically inherited substances (proteins or sugars) on the surface of the red blood cell's membrane. These substances are called ______________ because they are capable of invoking an immune reaction when the ___________ is exposed to a protein called an antibody.

antigen(s)

An individual will only produce the antibody for the antigens that [are/are not] on the sufaces of his/her RBCs

are NOT

dispose of gloves (if stained with blood), alcohol swabs, blood typing slides and paper towels that have come into contact with blood into this

biohazard box

a mostly clear narrow region between the PCV and the plasma consisting of white blood cells and platelets.

buffy coat

a motorized device used to spin a horizontally positioned glass tube of blood at a high speed for 5 minutes. The centrifugal force produced by the spinning device causes the heavier formed elements of the blood to accumulate at the bottom of the glass tube and the lighter plasma to remain at the top.

centrifuge

during a blood type detrmination, often called ______________, a blood sample is mixed with solutions called ______________, which contain a specific antibody to one of the RBC Antigens: A, B or RH.

cross-matching; anti-sera

White blood cells that contain visible granules using the light microscope

granulocytes

tube used to draw blood by capillary action and will not coagulate with the tube because of a coating of the anti-coagulat heparin on the inside of the tube

heparinized capillary tube

used to determine blood type

plastic blood typing slide, blood from lanced finger, and anti-A sera, anti-B sera and anti-Rh sera.

A specific antibody will attach to a specific antigen and ________ it for destruction

tag

can be easily identified in a blood smear because they are the only cells that contain nuclei. The classic method of categorizing these is by the presence or absence of visible granules in the cell's cytoplasm when viewed with the light microscope.
