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
ventricular muscle fiber repolarize
68
arteries
away from heart to capilaries high pressure smaller lumen. flow to capillaries
69
capillaries
site of exchange of substance btw blood n cells. connect small arterioles and vein extension of inner arterioles (squamous)
70
vein
return blood to atria. small. middle layer thin. thinner walls. have valves
71
vessel layers/tunics
``` tunica externa CT tunica media (smooth m) stretch, thick CT(elastic n collagenous) endothelium of tunica interna lumen ```
72
endothelium
prevent clotting secret dilate constrict vessel
73
vasomotor fiber
stimulattes smooth muscle to contract
74
arterioles
smaller thinner outer and middle layer
75
apillary permeability
small: smooth, akletal, cardiac large: endocrine, kidneys, lining small intestine largest: liver spleen bone marroe
76
capillary arrangement
higher rate if metabolism: denser
