- a 1. Functions
a. Transport of chemicals important to the clotting process.
b. Formation of a temporary patch in the walls of damaged blood vessels.
c. Active contraction after clot formation has occurred.
- b Proteins:
1. Albumins: viscosity, osmotic pressure, buffer, transports fatty acids, free bilirubin, thyroid hormones
2. Globulins: transports lipids, carbohydrates, hormones, ions, antibodies, and complement
3. Fibrinogen: blood clotting
4. Most plasma proteins synthesized by liver
5. Gamma globulins synthesized by plasma cells (B cells)
- c 1. Percent of blood (volume) that is RBCs - by centrifruge
2. Indicates problem but not what problem is
3. Normal 38-45%
- d 1. Hematocrit
2. Hemoglobin concentration
3. Total count for RBCs, reticulocytes, WBCs, and platelets
4. Differential WBC count

- e Stationary clot
5 Multiple choice questions
- 1. cells become thin, elongate and move either between or through endothelial cells of capillaries
2. migrate out of blood vessels and into tissue spaces.
- too many platelets (too much clotting)
- 1. die quickly, release chemicals to kill bacteria but you kill them too. they die to protect you.
2. AKA: polymorphonuclear leukocytes or PMNs
3. Highly mobile and very active PHAGOCYTIC cells
5. Secrete lysozyme.
6. Last 1-2 days.
7. Account for 60-70% of the WBC.
- 1. Transportation of dissolved gases, nutrients, hormones, and metabolic wastes. (by dissolved or a carrier molecule)
2. Regulation of the pH and ion composition of interstitial fluids. (HOMEOSTASIS)
3. Restriction of fluid losses at injury sites. (blood clots)
4. Defense against toxins and pathogens. (WBCs)
5. Stabilization of body temperature.
- hormones, enzymes
5 True/False questions
Leukocytosis → 1. Arrest of bleeding
2. Events preventing excessive blood loss
a. Vascular spasm: Vasoconstriction of damaged blood vessels.
b. Platelet plug formation
c. Coagulation or blood clotting
Red Blood Cells (Erythrocytes) → Transport of oxygen and carbon dioxide
White blood cells functions → Transport of oxygen and carbon dioxide
Rh Factor → platelets & plasma
RBC abnormalites: Anemia (3) → lack of hemoglobin, lack of RBC, can't carry as much oxygen
1. Iron Deficiency - most common, not enough Hemoglobin due to lack of iron. Iron effects function of making hemoglobin
2. Pernicious - lack of Vit. B12, not enough RBCs
Sickle Cell - destruction of RBCs, cells get trapped in blood vessels & they are broken down, then don't have enough RBCs.
