Flashcards in Anat blood Deck (76):
1

blood is a mixture of

cell fragments and dissolved biochem transport nutrients, O2, waste, hormones

2

function

transport substance btw cells and external envir, promote homeostasis

3

blood is a type of

CT

4

platelets

control blood loss from broken vessels

5

blood volume

8% of body weights
5 liters

6

hematocrit
packed cell volume

% of RBC in blood
45%

7

plasma

water, aa, carbohydrates, lipids, vitamin, hormones, electrocytes, waste

8

hematopoitic stem cells

into myeloid and lympoid respond to hematopoietic growth factors

9

thrombopoietin

stimulates large cell megakaryocytes to form platelets

10

RBC

biconcave
100-120 days

11

blue blood

rich in deoxyhemoglobin darker

12

erythropoiesis

blood cell production
before birth: yolk sac, liver, marrow

13

erythropoietin

hormone released from liver for RBC formation

14

anemia

deficiency of RBC

15

WBC

leukocytes

16

homrones that stimulate WBC production

interleukins
colony-stimulating factors

17

monocytes

largest WBC

18

WBC functions

phagocytise bact cells, produce antidbodies

19

platelets

thrombocytes
from ruptured cytoplasm of megakaryocytes

1/2 RBC, 10 days, no nucl

20

plasma protein

most abundant dissolved substance by weight

21

plasma protein function

albumins
globulins
fibrinogens

22

albumins

determine of osmotic pressure of plasma

23

globulin

tranpsort lipids n fat soluable vitamins

24

fibrinogens

blood coagulations

25

other plasma

water
O2 n CO2
dissolved notrogen
plasma nutrients: aa, simple sugar, nucelotides, lipids

26

granulocytes

WBC with granular cytoplasm neutrophil eosinophil basophil
lives 12h

27

agranulocytes

neutrophillack cytoplasmic granules
monocytes
lymphocytes

28

neutrophil 54-62

G
small granual
light purple
2-5 sections connected by strand
or
c shaped: younger
ingest bacteriak

28

29

eosinophil 1-3

darker gran. stain deep red. 2 lobes
allergy n worm

30

basophil 1

bigger n darker gran obscure view
histamine

31

monocytes 3-9

largest. kidney shaped macrophags

32

lymphocytes 25=33

small. nucleus circular fills up most of the cell
TB
live long

33

diapedesis

WBC move out of small vessels

34

wbcc

RBC destroyed 5000

35

leukocytosis

increase WBC indicate infection

36

eukopenia

decrease on WBC

37

DWBC

percentages of WBC types in blood

38

antigens

agglutinogens on RBC

39

antibodies

agglutinins
plasma
against a specc antigen

40

AnB

neither anti A nor B

41

O blood type.
neither A or B antigen

both anti A and anti-B

42

pulmonary circuit

deoxygenated blood to lungs

43

systemic

send oxygenated to body

44

heart

in mediastinum of thorax apex. left lung smaller

45

pericardium

outer
fibrous pericardium dense CT
parietal
pericardial cavity visceral/epicadium
myocardium endocardium

46

wall of the heart

epicarium reduce frictio capillary CT, epith, nerve myocardium cardiac muscle, thich endocaridum epi lines

47

atria

upper chamber. thin walls and receive blood

48

ventricle

lower, force blood out of heart
right: thinner

49

interatrial septum

separates atrium

50

nterventricular septum

seperates ventricles

51

right atria

recieves blood from vein that return deoxygenated blood

52

coronary sinus

vein drains blood into right atrium from the myocardium

53

tricuspid valve

right atrium-right ventricle. blood goes down not up
chordae tendineae: strings attach cusp
papillary muscle: mounds of cardiac muscle,contracts when ven contracts

54

right ventricle

pump blood to lung
exits through pulmonary
trunk

55

left ventricle

blood to body

56

eft atrium

recieves blood from lungs through 4 pulmonary vein

57

mitral/bicuspid valve

left atrium-ventricle

58

aortic valve

allow blood to go out of left ventricle to aorta

59

pulmonary valve

allow right ventrical to pulmonary trunk

60

blood flow

deoxy enters RA n it contracts then enters RV then it contracts moves through pulmonary valve n then ti alveoli (lung) . Oxy blood returns to heart through pulmonary valve,trunk, artieryvein to LA n it contracts n into ventrical n into aortic valve and its branche

61

systole

contract lubbV

62

diastole

relax duppV

63

conduction

fw myofibrils

64

conduction list
stimulate muscle fiber to contract. blood from ventrical to aorta n pulmonary trunk. trigger: depolarized

SA node
atrial syncytium junctional fibers
AV node
AV bundle
bundle branches purkinje fibers ventricular syncytium

65

P

depolarization of atrial fiber. atria contract

66

QRS

repolarize atria depolarize at bottom of ventrical

67

T

69

capillaries

site of exchange of substance btw blood n cells.
connect small arterioles and vein
extension of inner arterioles (squamous)
