Question 27

anemia

Answer 27

- bloods oxygen-carrying capacity is too low to support normal metabolism - may result in decrease in RBCs or decreased hemoglobin content in RBCs

Question 28

polycythemia

Answer 28

abnormal excess of RBCs that increases blood viscosity

Question 29

leukopenia

Answer 29

abnormally low white blood cell count/ below 4000 cells per mm2(squared)

Question 30

leukocytosis

Answer 30

- increased WBCs - over 11,000 cells per microliter - normal homeostatic response to an infection in the body

Question 31

leukemia

Answer 31

overproduction of abnormal WBCs, accompanies by a reduction in the number of RBCs and platelets

Question 32

sickle cell anemia

Answer 32

abnormal hemoglobin, results from a change in one of the 146 amino acids in a beta chain of the globin molecule. Cell becomes irregular shaped and is not able to carry oxygen

Question 33

iron-deficiency anemia

Answer 33

inadequate intake of iron-containing foods or impaired iron absorption (iron is a part of hemoglobin)

cuagulation

Answer 34

blood clotting

Question 35

hematocrit

Answer 35

percentage of RBCs present in a given volume

Question 36

centrifuging

Answer 36

centrifugal force packs down heavier formed elements in a capillary tube, and less dense plasma remains at the top. (In order: plasma, buffy coat (leukocytes and platelets), and erythrocytes at the bottom)
