Q

Whats the job of cappillaries

A

Provide a bridge between the arteries(arterioles), smallest branches of arteries to smallest branches of veins. venule, allow microscopic molecules to be exchanged between blood & force fluid nearly everywhere in body

Q

What happens in the heart during a myocardial infarction (MI)

A

Elevated cardiac enzyme, abnormal CK,LDH enzyme. Levels of CK rise 6-24hrs after MI, LDH levels elevate in patients w/ congestive heart failure and peak 48hrs after an MI 6hr window to stop progression of the cardiac event before permanent damage. 65% of MIi deaths occur w/in the 1st hr

25
Cardiac Arrest
When the heart suddenly stops
26
name/describe the aneurysm
Dissecting Aneurysm- splitting of arterial wall, )usally inner lining) layers, creating a bulge between the layers
27
Thallium Scan
Test using radioactive thallium to asss coronary artery disease
28
Palpitation
Fluttering of the heart
29
Ischemia
In adequate supply of blood and oxygen to tissues from arterial blockage
30
Cardiac Tamponade
Heart compression caused by fluid accumulation in the pericardial sac
31
Echocardiogram
image of the heart produced by ultra sound
32
Myocardium
Mostly made of cardiac muscle tissue
33
Describe the heart in location,size, and placement
4 chamber pumping organ. Gen structure.- hollow, funnel shaped muscular pump, tilted position to the left. bulk of heart is to the left of the sternum. Approx. size of clenched fist. 13cm(5.2 in), 8cm (3.2 in). wide. Heart size depends on indivisual and excercise level
34
Endocardium
Inner layer, continous for inner lining of blood vessels
35
Cardiac Catherization
Procedure where flexible tube is inserted into coronary vessels of a peripheral artery for images
36
The function of a Vessel
delivers electrolytes,hormones, nutrients oxygen to tissues
37
Define Plaque
Lipid/fats deposits in arterial wall
38
Name/describe the Aneurysm
Fusifrom Aneurysm Enlongated, spindle-shaped dialation of the arterial wall
39
Mitral Stenosis
NArrowing of mitral valve opening impeding blood flow
40
Cardiac Cycle
A complete round of heart contraction and relaxation; a complete heart beat
41
Spell the word that means surgical removal of plaque from an artery
A-t-h-e-r-e-c-t-o-m-y
42
2 lower chambers
Ventricles- force blood out of the heart into arteries. Left ventricle is thicker than right,b/c its a stronger muscle. Right ventricle pumps blood a shorter distance
43
\_\_\_\_are less elastic, smooth muscle than arteries
Veins are less elastic, smooth muscle than arteries
44
Pulmonary Arteries
Transport blood to the R &L lungs
45
What causes the heart to beat
Electrical impulses that stimulate contractions called the cardiac conduction system
46
What condition primarily causes Mitral Stenosis
Rheumatic Heart disease which is an autoimmune disorder
47
2 upper chambers
Atria (singular=atrum) called this b/c in earlier times the atria was the first room in a house
48
Whats the main job of the CV system
Pump blood through out the body
49
What are normal ranges for adult BP
120/80
50
What usually causes endocarditis
bacterial/ fungal infection elsewhere in the body
51
Bruit
Swishing sound from turbulent blood flow
52
Hyertension
Chronic abnormally high BP
53
Atherosclerosis
Plaque in inner arterial wall
54
Spell the word that means: Atherectomy including removal of diseased portions of atrial lining
E-n-d-a-r-t-e-r-e-c-o-m-y
55
What valve is affected by mitral valve prolapse?
Left bicuspid(mitral)valve. Mostly congenital, causes blood regurgitation. Usually no S/S b/c volume of blood supply in opposite direction is not significant
56
Fibrillation
Irregular, uncoordinated heart contractions
57
Heart Block
Condition caused y impairment of the conductinh system
58
Veins ____ blood ___ the heart
Veins RETURN blood TO the heart
59
Atrial septal Defect
Abnormal opening between atria that allow blood to shunt back and forth
60
Name/describe the aneurysm
Saccular Aneurysm sac-like bulb on one side
61
List the flow of blood through the heart
Inferior Vena cava & superior cena cava- right atrium-right atrium-tricuspid valve-right ventricle-pulmonary valve-R&L pulmonary arteries- R&L lungs- R&L pulmonary veins-Left atrium- bicuspid valve- left ventricle-left ventricle-aortic valve-aorta-systemic circulation-back the superior/inferior vena cave
62
List the flow of blood through the systemic circuit
heart-aorta-arterioles-capillaries-venules-veins-superior-and inferior venae cavae-heart
63
Pericardium
Surrounds/protects heart to layers, inner visceral (epicardium), outter parietal layer
64
Arteriosclerosis
Hardening of arteries
65
Holter Monitor
Portable device for recording an ECG(EKG over an extended time period
66
MVP
Mitral Valve Prolapse When flaps don't close properly and forms the prolapse
67
What does a vein have that an artery doesnt?
A valve
68
Aortic Coarctation
Congenital narrowing of the aorta
69
Angina Pectoris
Radiating chest pain
70
Angiogram
X-ray of blood vessels after injection of dye into the bloodstream
71
Angioplasty
Surgical repair of diseased vessel
72
Where is lumen located
Space inside tubular artery
73
