1

– pale yellow fluid
-volume remains relatively constant

plasma

2

Plasma Proteins
contributes to the osmotic pressure of blood

albumin

3

Plasma Proteins
some are part of the immune system (antibodies and complement), some are transport molecules, some are clotting factors (fibrinogen)

globulin

4

Plasma Proteins
clotting factor (converted to fibrin)

fibrinogen

5

process of blood cell production

hematopoiesis

6

plasma without clotting factors

serum

7

where all formed elements are derived
-differentiate to give rise to different cell lines

stem cells or hemacytoblasts

8

main component of RBC
-accounts for about 1/3 of RBC’s volume and red color

hemoglobin

9

– responsible for oxygen transport
-consists of 4 protein chains and 4 heme groups

hemoglobin

10

has 2/3 of the body’s iron

hemoglobin

11

color of blood
Hemoglobin + O2

bright red

12

color of blood
Hemoglobin (without O2)

dark red

13

– binds to iron in hemoglobin about 210 times more readily than does oxygen
-does not tend to unbind
-nausea, headache, unconsciousness, death

carbon monoxide

14

produced in tissues
-transported to the lungs where it is removed from the blood
-its transport involves bicarbonate ions, hemoglobin, plasma
-much is transported in the form of bicarbonate ions
-can reversibly bind to the globin of hemoglobin

carbon dioxide

15

catalyzes a reaction that converts carbon dioxide and water into a H ion and HCO3- ion

carbonic anhydrase

16

give rise to the red blood cell line

Proerythroblast

17


Requirements for the Cell Division of RBC:

Foliate
B12
Iron

18

hormone that stimulates red bone marrow to produce more RBC
-negative feedback mechanism

erythropoeitin

19

in what form is heme converted during hemoglobin breakdown

bilirubin

20

– yellowish skin color due to build up of bilirubin in the circulation

jaundice

21

-spherical cells that lack hemoglobin
-larger than RBC
-has nucleus
-leaves the blood and travels by amoeboid movement

WBC

22

most common type of WBC
-small granules (stain in both acidic and basic dyes)
-2-4 lobes
-remain in blood for a short time
-phagocytize microorganisms

neutrophil

23

– least common WBC
-large granules (blue or purple with basic dyes)
-release histamine and heparin (prevents formation of clots)

basophil

24

– bright red granules with eosin (acidic stain)
-2 lobed nucleus
-involved in inflammatory responses associated with allergies and asthma
-involved in destroying worm parasites

eosinophil

25

– smallest WBC
-has a thin, unnoticeable ring (plasma membrane)
-involved in body’s immune response
-production of antibodies

lymphocytes

26

largest of the WBC
-leave the blood, enter tissues, enlarge and become macrophages

monocytes

27

phagocytize bacteria, dead cells, cell fragments, etc
-present the processed substances to lymphocytes to activate them

macrophages

28

-produced in red bone marrow from megakaryocytes (large cells)

platelets

29

blood loss prevention
immediate but temporary constriction of a blood vessel
-results when a smooth muscle within the vessel contracts
-also produced by chemicals

vascular spasm

30

blood loss prevention
accumulation of platelets that can seal up a small break in a blood vessel

platelet plug
