The circulatory system can be divided into |
Cardiovascular and lymphatic systems |
|
|
The 3 components of the cardiovascular system |
Blood, heart, vessels |
|
|
Blood is what type of tissue? |
Connective tissue |
|
|
Name the components of the blood |
Plasma, formed elements (erythrocytes, leukocytes, thrombocytes) |
|
|
Liquid fraction, mostly water, about 55% of blood |
Plasma |
|
|
45% off blood is made of |
Formed elements |
|
|
All cells develop in |
The red bone marrow |
|
|
Biconcave discs; no nucleus; 5 million mm3 |
Erythrocytes |
|
|
Name the 5 types of leukocytes (Never Let Monkeys Eat Bananas) |
Eosinophil, basophil, neutrophil, monocyte, lymphocyte |
|
|
Have nucleus; pale unless stained; 5,000 - 10,000 per mm3 |
Leukocytes |
|
|
Very small; no nucleus; typically found in clusters; 150,000 - 400,000 per mm3 |
Thrombocytes |
|
|
Thrombocytes start off as |
Megakaryocytes; pieces break off to create platelets |
|
|
The ratio of packed blood cells to the total volume |
Hematocrit |
|
|
Normal hematocrit levels |
Females: 42%, males: 47% |
|
|
Leukocytes & thrombocytes make up how much of the food elements |
<1% |
|
|
100 leukocytes are counted and classified |
Differential white blood cell count |
|
|
Stain used to prepare a differential white blood cell count |
Wright stain |
|
|
Identify the granulocytes |
Eosinophils 2-4%, basophils <1%, neutrophils 50-70% |
|
|
Cytoplasm filled with large orange to red marble like granules; symmetrical bilobed nucleus |
Eosinophils |
|
|
Cytoplasm with numerous large purple black granules which hide the nucleus; produce heparin and histamine |
Basophils |
|
|
Pink purple cytoplasm with fine pepper granules; multilobed nucleus; phagocyte |
Neutrophil |
|
|
Do not have granules in cytoplasm which stain |
Agranulocytes |
|
|
Small to large cells; baby blue cytoplasm; large, nearly spherical nucleus; 20-45% of all leukocytes |
Lymphocyte |
|
|
Large cells, blue gray cytoplasm; nucleus indented; phagocyte; 3-8% |
Monocyte |
|
|
Present on the surface of each red blood cell; genetically determined |
Antigens (proteins) |
|
|
Three genetic options that genes can code: |
Antigen A, antigen B, no antigen |
|
|
Agglutination occurs when |
Antibodies bind to their antigens |
|
|
Blood type A has which antigen and which antibody? |
Antigen A, antibody B |
|
|

Heparinized |
|
|
How long is blood spun down in the centrifuge |
About 5 minutes |
|
|
Hematocrit calculation |
Red blood cell volume divided by total volume times 100 |

|
Largest formed element |
Monocyte |
|
|
Polymorphonuclear |
Neutrophil |
