Anatomy

1. Nutrients, waste, hormones, heat, antibodies.

2. Hemoprytoblast , stem cells are found primarily in red bone marrow and are the precursor cells for all the types of blood cells.

3. RBC = 4.5-6 million

Wbc = 5,000-10,000

Platelets = 150,000-300,000

Home globin = 12-18 grams 100ml

Hematocrit = 38% - 48%

4. Red blood cells decrease anemia, and increase polycythemia.

5. Protein and iron are necessary for the synthesis of hemoglobin and become part of hemoglobin molecules. The vitiamins folic acid and b12 are required for dna synthesis in the stem cell of the red bone marrow.

6. Part of the hemoglobin is the heme portion. The heme is converted to bilirubin by macrophages. The liver removes bilirubin from circulation and excretes it into bile bilirubin is a bile pigment.

7. A person should receive there own blood type but if it is not available then type o may be given. Because type o rbc have neither the A or B antigens and will not react with whatever antibodies the recipient may have, if only one unit is given plama will be diluted and will not have a harmful effect .

8. A.brand cells

b.lymphocyte

c.eosinophils

d.lymphocyte

e.heparin

f. T cells

9. when the capillaries rupture the damage is too slight to initiate the formation of a blood clot.

10.wen a large vessel such as a artery or vein is severed, the smooth muscle in its wall contracts in response to the damage.

11.a.miniral

b. liver

c. vitamin k

d.damage tissue, calcium ions, plasma proteins prothrombin, fibrinogen.

12.once clot has formed and bleeding has stopped this occurs. It requires platlets, ATP, Factor 13 and involves folding threads to ll the edges the rupture in the vessel wall closer together.

13. its prevented by very smooth endothelium that lines blood vessels, heparin, which inhibits the clotting process, and antithrombin which inactivates excess thrombin.

14.thickness or restinces to flow. Blood is about 3 to 5 times thicker than...
