Flashcards in Chapter 16 Deck (29):
1

Extracellular matrix of the blood

Plasma

2

Plasma protein, various functions (name 2)

Globulins (antibodies, transporters)

3

Plasma protein,fibrin precursor

Fibrinogen

4

Plasma protein, transfers iron

Transferrin

5

RBCs

Erythrocytes

6

WBCs

Leukocytes

7

Platelets

Thrombocytes

8

Engulfing WBCs (name them)

Phagocytes (neutrophils, monocytes/macrophages)

9

Targeted-response WBCs (name them)

Immunocytes (lymphocytes)

10

Granular appearance WBCs (name them)

Granulocytes (neutrophils, basophils, eosinophils)

11

Name for tissue-based basophils

Mast cells

12

Mother cell of platelets

Megakaryocyte

13

Hematopoiesis

Formation of blood cells

14

Stroma

Supporting tissue of bone marrow

15

Erythropoietin (EPO) (how is it released?)

Stimulates RBC production (hypoxia triggers release from kidneys)

16

Hematocrit (what's normal?)

Blood volume occupied by RBCs (42%-45%)

17

Erythroblast

Nucleate RBC precursor

18

Reticulocyte

Anucleate, circulating RBC precursor

19

Hemostasis

Maintenance of blood volume

20

Steps of Hemostasis

1. Vasoconstriction
2. Platelet Plug
3. Coagulation

21

Fibrinolysis

Breakdown of fibrin

22

Fibrin

Stabilizes platelet plug into clot

23

Thrombin

Induces fibrin formation

24

Plasmin

Breaks down fibrin

25

Plasminogen

Plasmin precursor

26

tissue plasminogen activator (tPA)

Converts plasminogen to plasmin

27

Coumarin

Blocks vitamin K cofactors in thrombin synthesis

28

Heparin

Blocks coagulation cascade active factors

29

Comprises 60% of all plasma proteins

Albumin
