Q

Arteries

A

Carry blood away from the heart
Bright red
As they travel through the heart they get smaller
Muscular& elastic so that they can expand and contract with the pumping beat of the heart

30
P-PRwave
Atrial depolarization
31
QRS wave
Ventricular depolarization
32
T Wave
Ventricular repolarization
33
Cardiac Conduction system 1
Sinoatrial (SA) node “pacemaker”, where the electrical impulse begins. A wave of electricity travels through the SA node causing the atrias to contract
34
Cardiac Conduction system 2
Atrioventricle(AV) node is simulated
35
Cardiac Conduction system 3
AV node transfers the electrical wave to the atrioventricle bundle
36
Cardiac conduction system 4
The electrical signal travels down the bundle branches where the Purkinje fibers are stimulated causing ventricles to contract
37
P wave is
Contraction of the atrias
38
QRS wave is
The contraction of the ventricles. The atrias relax while ventricles contract
39
T Wave is
The relaxation of the ventricles
40
Pulse
Surge of blood caused by heart contraction, usually equal to heart rate
41
Normal pulse
60-100 bpm
42
Blood pressure
Measurement of the amount of pressure exerted against the walls of the blood vessels
43
Normal blood pressure
120/80
44
Systolic
When ventricles contract; highest
45
Diastolic
When ventricles relax. Lowest pressure
46
Hypertension
Blood pressure over 140/90
47
Hypotension
Blood pressure under 90/60
48
Upper respiratory tract
Nasal and oral passage, pharynx larynx
49
Lower respiratory tract
Trachea, bronchi, brochioles, alveoli
50
Nasal cavity
Air enters through 2 opening, nares Divided down the center by nasal septum Filters debris and bacteria from the air Mucous secreted by mucous membranes
51
Epistaxis
Bloody nose
52
Pharynx
The throat Used for both respiratory and digestive purposes 3 parts, nasopharynx, oropharynx, laryngopharnx
53
Larynx
Voice box, contains vocal chords
54
Epiglottis
Lid on trachea Prevents food or liquid from going into lungs
55
Bradycardia
Slow heart rate
56
Cardiomegaly
Abnormal enlargement of the heart
57
Tachycardia
Fast heart rate
58
Phlebitis
Inflammation of veins
59
Ischemia
Reduced blood flow
60
Murmur
Sound of blood flowing through heart
61
Palpitations
Rapid, strong, irregular heart beat
62
Congenital septal defect
A heart defect due to an abnormal connection between the ventricles
63
Heart valve prolapse
Improper closure of valv
64
Heart valve stenosis
Narrowing of the valve in a large blood vessel
