Definition
| Red Blood Cells (Erythrocytes), White Blood Cells (Leukocytes), and Platelets |
|
|
Term
|
Definition
| Red Blood Cells. The most abundant formed element (99.9%). Essential for transport of oxygen in the blood. |
|
|
Term
|
Definition
| White Blood Cells. Involved in the body's defense mechanisms. There are five different classes (Neutrophils, Eosinophils, Basophils, Monocytes, and Lymphocytes). |
|
|
Term
|
Definition
| Small, membrane-bound cell fragments that contain enzymes and other substances important to the process of clotting. |
|

Term
|
Definition
| Process through which formed elements are produced. |
|
|
Term
|
Definition
| Pluripotent stem cells that divide to produce either myeloid stem cells or lymphoid stem cells. |
|
|
Term
|
Definition
| Plasma and the formed elements. |

| Characteristics of Whole Blood |
|
Definition
| 1. Temperature (~38 degrees C)
2. Viscosity (5x water)
3. pH (7.4) |
|
|
Term
|
Definition
| Obtaining whole blood from a superficial vein, such as the median cubital vein on the anterior surface of the elbow. |
|
|
Term
|
Definition
| "Arterial Stick" can be used for checking the efficiency of gas exchange at the lungs. Generally drawn from the radial artery at the wrist or the brachial artery at the elbow. |
|
|
Term
|
Definition
| Plasma makes up 46-63 percent of the volume of whole blood. 92% of plasma is water. Resembles the composition of interstitial fluid due to water, ions, and small solutes which are continually exchanged between the two. |
|
|
Term
| Plasma vs. Interstitial Fluid Differences |
|
Definition
| 1. The concentrations of dissolved proteins because plasma proteins cannot cross the capillary walls.
2. Levels of respiratory gases (oxygen and carbon dioxide). |
