30
Q

P-PRwave

A

Atrial depolarization

31
Q

QRS wave

A

Ventricular depolarization

32
Q

T Wave

A

Ventricular repolarization

33
Q

Cardiac Conduction system 1

A

Sinoatrial (SA) node “pacemaker”, where the electrical impulse begins. A wave of electricity travels through the SA node causing the atrias to contract

34
Q

Cardiac Conduction system 2

A

Atrioventricle(AV) node is simulated

35
Q

Cardiac Conduction system 3

A

AV node transfers the electrical wave to the atrioventricle bundle

36
Q

Cardiac conduction system 4

A

The electrical signal travels down the bundle branches where the Purkinje fibers are stimulated causing ventricles to contract

37
Q

P wave is

A

Contraction of the atrias

38
Q

QRS wave is

A

The contraction of the ventricles. The atrias relax while ventricles contract

39
Q

T Wave is

A

The relaxation of the ventricles

40
Q

Pulse

A

Surge of blood caused by heart contraction, usually equal to heart rate

41
Q

Normal pulse

A

60-100 bpm

42
Q

Blood pressure

A

Measurement of the amount of pressure exerted against the walls of the blood vessels

43
Q

Normal blood pressure

A

120/80

44
Q

Systolic

A

When ventricles contract; highest

45
Q

Diastolic

A

When ventricles relax. Lowest pressure

46
Q

Hypertension

A

Blood pressure over 140/90

47
Q

Hypotension

A

Blood pressure under 90/60

48
Q

Upper respiratory tract

A

Nasal and oral passage, pharynx larynx

49
Q

Lower respiratory tract

A

Trachea, bronchi, brochioles, alveoli

50
Q

Nasal cavity

A

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
Q

Epistaxis

A

Bloody nose

52
Q

Larynx

A

Voice box, contains vocal chords

54
Q

Epiglottis

A

Lid on trachea
Prevents food or liquid from going into lungs

55
Q

Bradycardia

A

Slow heart rate

56
Q

Fast heart rate

58
Q

Phlebitis

A

Inflammation of veins

59
Q

Ischemia

A

Reduced blood flow

60
Q

Murmur

A

Sound of blood flowing through heart

61
Q

Palpitations

A

Rapid, strong, irregular heart beat

62
Q

Congenital septal defect

A

A heart defect due to an abnormal connection between the ventricles

63
Q

Heart valve prolapse

A

Improper closure of valv

64
