3. pigment of blood - hemoglobin mixing w/oxygen
4. contain iron, needed to make hemoglobin
- b 1. in blood
2. Leave circulation & become macrophages.
3. Mobile and highly PHAGOCYTIC cells (don't die after cleanup)
4. Capable of engulfing large bacterial organisms & viral infected cells
5. Account for 3-8% of the WBC.
- c 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.
- d 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
- e 1. A network of threadlike fibrin fibers, trapped blood cells, platelets and fluid
2. Clot retraction. Fibrin threads of clot attached to blood vessel walls.
a. Platelets produce processes that attach to fibrin threads.
b. Actin and myosin molecules within platelets contract, pulling edges of wound together and squeezing out serum.
5 Multiple choice questions
- 1. Leave circulation (blood) and enter tissues during inflammatory response. (get of stuff after allergic response)
2. Prevalent in allergic reactions.
3. Destroy inflammatory chemicals like histamine.
4. Numerous in lining of respiratory and digestive tracts
5. Account for 2-4% of the WBC.
6. go after parasitic worms
- 1. RBC life span - 105 to 120 days
2. Damaged RBCs removed by spleen & liver
3. Broken down into heme & globin
4. Globin - amino acids
5. Heme - (iron mostly)
a. Biliverdin (green) by product, breaks down bilirubin
b. Bilirubin (yellow) by product of iron
Bruise - break down hemoglobin
spleen - remove any damaged RBCs, WBCs & platelets
- 1. Function: Transport of oxygen and carbon dioxide
2. Biconcave discs (b/c no nucleus)
3. One-third hemoglobin
4. Lacks nuclei, mitochondria and ribosomes
5. can repair itself
6. not much energy
7. limited lifespan
8. carbonic anhydrase can be found in RBC
- 1. Protein that reacts against a specific antigen
2. in the plasma
3. goes after foreign blood types. For example, if you are type A & you get type B, antibody will go after type B
Note: antibodies is what on test, not agglutinins
- three characteristics
1. Adhesive - stickey
2. Aggregate - platelets come together
3. Agglutination - large amount clump together, it's NOT a clump
4. Pinched off of megakaryocyte
5. Thrombocytopenia - too little platelets (bleeding to death)
6. Thrombocytosis - too many platelets (too much clotting)
5 True/False questions
Thrombocytosis → too many platelets (too much clotting)
Rh Factor → platelets & plasma
RBC abnormalites: Polycythemia → 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.
Platelets function → ...
White Blood Cells: Chemotaxis → 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.
