Q

how does blood flow on the left side of the heart

A

oxygenated blood goes from the lungs to the left atrium
then to left ventircle
then out to the body
then goes to the right side of the heart

Q

how does deoxygenated blood flow on the right side of the heart

A

the blood comes from the body to the right atrium
then to the right ventricle
then back out to the body
to be entered again to the left side of the heart

Q

on the 2nd beat of the heart the valves

A

close and stops blood from flowing backwards
ventricles contract and blood is pushed out of the heart
then valves shut

25
what is an EKG
electrocardiogram measures heartbeats
26
what are the nodes for natural pacemaker
SA VA
27
what is an arrhythmia
heart beat irregularity
28
what are symptoms of arrhythmia
tired dizzy pain in chest
29
what is the solution for arrhytmia
artificial pacemaker
30
what are the symptoms of post heart attack fibrillation (flatlining)
electrical signals are not coordinated
31
what is the solution of post heart attach fibrillation (flatlining)
shock from a defribrillator resets heart beat rhythm
32
where does gas exchange happen
lungs
33
what two circuits are interregulated
pulmonary and systemic
34
what is the pulmonary circuit
deoxygenated blood to the lungs it realases carbon dioxide and picks up oxygen
35
what is the systemic circuit
oxygenated blood to body picks up carbon dioxide from cells
36
artieries carries blood
away from the heart
37
artery have what type of blood
oxygenated
38
arteries stretch
under pressure
39
what pushes the blood in arteries
muscles
40
how does arteries look like
thick muscle and elastic fibers
41
veins carries blood
towards the heart
42
what regulates flow direction in veins
valves
43
what surrounds the veins to push the blood
muscles
44
what does Veins look like
thin muscle and elastic fibers
45
veins have what type of blood
deoxygenated
46
capillaries link
arteries with veins
47
capillaries exchange
materials between the blood and other body cells
48
how thick is the wall of a capillary
1 cell thick
49
what do you think when you think of capillaries
tube itself
50
what is the hearts own blood supply called
coronary arteries
51
coronary =
heart
52
what is in blood
oxygen red blood cells plasma carbon dioxide hormones platelets waste white blood cell
53
blood has how many layers
3
54
what is the top layer of blood
plasma
55
what is the middle layer of blood
buffy coat
56
what is the bottom layer of blood
red blood cells
57
what is the function of red blood cells
transport oxygen or carbon dioxide
58
why are red blood cells red
from hemoglobins when they bind to oxygen or carbon dioxide
59
what is the shape of red blood celss
disk shaped or biconcave
60
why are red blood cells disk shaped or biconcave
to maximize surface area for efficent latching on
61
red blood cells circulate for
120 days
62
how many red blood cells are in 1 drop of blood
5 mil
63
red blood cells have no
nucleus and organelles
64
erythrocytes is another name for
red blood cells
65
where are red blood cells created
bone marrow
66
how does red blood cells replicate
hematopoietic stem cells
67
what is the main job of blood platelets
clotting
68
blood platelets are also known as
thrombocytes
69
thrombocytes help repair
damaged blood vessels by adhering to their broken edges
70
what is the process of clot formation in order
vessel torn vessel constricts platelets attach to blood vessel walls platelets release fibrin fibrin traps red blood cells clotting cascade started
71
what is fibrin
protein that seals by sticking to each other
72
what is hemophelia
severe hemorrhaging and no ability to clot
73
hemophelia is a factor
8 mutation
74
white bloods cells are
immune cells
75
what are the 2 main white blood cells
lymphocytes and macrophages
76
our bodies will fight anthing
foriegn
77
blood type o
has no protiens attatched (null)
78
Rh factor is
+
79
no Rh is
-
80
the + or - on blood types signify
additional protein on blood cells
81
why is knowing blood types important
blood donation
82
blood type o- is considered
universal donor
83
blood type ab+ is considered
universal acceptor
84
what is an artery blockage
blocks oxygen to part of the heart muscle
85
artery blockage can create
plaque
86
what are symptoms of artery blockage
pain in chest nasuea shortness of breath cold sweats
87
what is the solution to artery blockage
go to the hospital
88
what is prevention of artery blockage
good diet excersize
89
when an artery is blocked or ruptured in a brain can cause a
stroke
90
lack of oxygen to the brain cells can cause a
stroke
91
what are symptoms of a stroke
confusion loss of movement loss of vision
92
what is prevention of a stroke
