fibrinogen 4%

24
Q

where does hemoglobin release o2

A

tissue level

25
Q

true or false: blood does not have nuclei or organelles

A

true

26
Q

function of the spleen

A

removes old RBCs

stores healthy RBC

27
Q

what generates new RBCs

A

hemopoietic tissues

28
Q

what controls erythropoiesis

A

kidneys

29
Q

what stimulates erythropoiesis

A

erythropoietin

30
Q

process of erythropoietin secretion

A

kidneys detect reduced o2
erythropoietin goes into the blood
erythropoietin stimulates erythropoiesis in bone marrow
more RBCs are released in blood

31
Q

what kind of cell are platelets

A

cell fragments

32
Q

where do platelets come from

A

shed from megakaryocytes in bone marrow

33
Q

what parts of the heart are involved in pulmonary circulation

A

right atrium

right ventricle

34
Q

what parts of the heart are involved in systemic circulation

A

left ventricle

left atrium

35
Q

blood circulation

A

all blood from superior and inferior vena cava -> right atrium -> tricuspid valve -> right ventricle -> pulmonary valve -> pulmonary trunk -> pulmonary artery -> lungs -> left atrium -> bicuspid valve -> left ventricle -> aorta

36
Q

where does the right side of the heart send blood

A

lungs

37
Q

where does the left side of the heart send blood

A

all over body

38
Q

what carries blood away from the heart

A

arteries

39
Q

why does blood move fast in the arteries

A

large radii = little resistance

40
Q

true or false: arteries are not elastic

A

false

41
Q

arterosclerosis

A

heartening of the arteries

42
Q

describe the vessels of a person with high blood pressure

constricted

43
Q

what allows arteries to expand

A

elastin fibers

44
Q

when does systolic blood pressure occur

A

ventricals contract

45
Q

which number is systolic blood pressure on a reading

A

top

46
Q

which number is diastolic blood pressure on a reading

A

bottom

47
Q

when does diastolic blood pressure occur

A

ventricles relax

48
Q

what is the main driving force of blood flow

A

mean arterial pressure

49
Q

formula of mean arterial pressure

A

= diastolic pressure+ (1/3(systolic pressure - diastolic pressure))

50
Q

what controls vessels contracting and relaxing

A

autonomic nervous system

51
Q

condition where fluid stay in interstitial space

A

edema

52
Q

hydrostatic pressure

A

pushes nutrients out

53
Q

what happens to blood pressure during hydrostatic pressure

A

increases

54
Q

what size molecules does hydrostatic pressure deal with

A

small

55
Q

what size molecules does oncotic pressure deal with
