 Blood | Circulating fluid of the body |
| Cardiocasvular System | an internal transport network |
| Plasma | contains dissolved proteins rather than the network of insoluble flibers like those in loose connective tissue or cartilage |
| Formed Elements | blood cells and cell fragments suspended in plasma |
| Red Blood Cells (RBC) | transport oxygen and carbon dioxide |
| erythrocytes | transport oxygen and carbon dioxide (RBC) |
| White Blood Cells (WBC) | function as part of the body's defense mechanisms |
| leukocytes | function as part of the body's defense mechanisms (WBC) |
| Platelets | small; membrane-enclosed packets of cytoplasm that contains enzymes and factors impportant to blood clotting |
| hemopoiesis | (hematopoiesis) formed elements are produced |
| whole blood | made up of the plasma and formed elements |
| fractionated | when whole blood cells are seperated |
| venipuncture | when fresh whole blood is collected from a superficial vein, such as the median cubital vein on the anterior surface of the elbow |
| arterial puncutre | "arterial stick" may be required for evaluating the efficency of gas exchange at the lungs |
| Whole blood sources that have the same physical characteristics | Temperature; Viscosity; pH |
| Albumins | constitute 60 percent of all plasma proteins |
| Globulins | accounting for another 35 percent of plasma proteins, inclube antibodies and transport proteins |
| antibodies (immunoglobulins) | attack foreign proteins and pathogens |
| transport protiens | bind small ions, hormones or compounds that might otherwise be lost at the kidneys or have very low solubility in water |
| fibrinogen | third type of plasma protein; functions in blood clotting |
| fibrin | vhen fibrinogen molecules interact and convert to form large insoluble strands of fibrin |
| serum | the fluid left after the clotting proteins are remo |
| Plasma cells | produce antibodies |
