Chapter 16

Question 1

normocyte

Answer 1

normal volume

Question 2

macrocytic

Answer 2

larger volume; this happens if a person has a deficiency in B12 or folic acid

Question 3

Microcytic

Answer 3

smaller volume; not producing appropriate amount of Hb and can result in iron deficiency

Question 4

Mean corpuscular Hb

Answer 4

average amount of Hb they carry

Question 5

normochromic

Answer 5

normal

Question 6

hyperchromic

Answer 6

more Hb

Question 7

hypochromic

Answer 7

not enough; usually microcytic

Question 8

a full molecule of Hb can carry

Answer 8

4 molecules of oxygen

Question 9

bilirubin

Answer 9

goes to liver where it is converted to urobilin or stercobilin

Question 10

RBC count

Answer 10

females - 3.9-5.6 million per microliter

males - 4.5-6.5 million per microliter

Question 11

erythrocytopenia

Answer 11

low RBC count

Question 12

polycythemia

Answer 12

high RBC count

Question 13

relative

Answer 13

right number but higher concentration

Question 14

polycythemia vera

Answer 14

high RBC count but you have not suffered hypoxia

Question 15

secondary or compensatory

Answer 15

high RBC and hypoxia; high altitude or pregnancy

Question 16

Hematocrit

Answer 16

ratio of RBC to total volume

females: 42% +/- 5%
males: 47% +/- 7%

Question 17

leukocytopenia

Answer 17

too few WBC

Question 18

leukocytosis

Answer 18

too many WBC; leukemia is an extreme form

Question 19

platelet count

Answer 19

1.5 x 10^5 - 4.5 x 10^5

Question 20

thrombocytopenia

Answer 20

too few platelets

Question 21

thrombocyosis

Answer 21

too many platelets

Question 22

Platelet activation

Answer 22

exposure to collagen, Von Wille factor promotes platelets to stick to collagen, platelets secrete serotonin to vasoconstrict, PAT gets more platelets to come, produces thromboxane A which promotes aggregation and vasoconstriction; COX enzymes used to produce thromboxane A

Question 23

coagulation

Answer 23

intrinsic pathway: collagen activates factor 12
extrinsic pathway: activation of factors 3 and 7
activation of factor 10, prothrombin, thrombin converts fibrinogen to fibrin which makes the stabilized clot

Question 24

break clot

Answer 24

thrombin and t-PA convert plasminogen to plasmic which snips fibrin threads
