Q

Explain how the thickness of the myocardium is dependent upon the function of the chamber

A

The thickness of the chamber wall is dependent upon the function of the chamber. Ventricles are thicker than atrias with the left ventricle being the thickest

drains the heart wall of blood and empties into the right atrium traveling through the coronary sinuses

right atrium
39
a complete heartbeat consisting of contraction and relaxation of both atrias and ventricles
cardiac cycle
40
the highly populated region of the chest between the lungs
mediastinum
41
muscular partition the divides the heart into right and left halves
septum
42
commonly called the pace maker locoation: right atrial wall near the opening of the superior vena cava
sinoatrial node - SA Node
43
location: lower part pf the right atrium near the interatrial septum
atrioventricular node- AV Node
44
location:originates in the AV Node and extends down both sides of the interventricular septum
AV Bundle- Bundle of HIS
45
function of the SA Node...
originates the the electrical discharger that causes the heart to contract
46
location: lateral walls of the ventricles
purkinje fibers
47
function of the AV Node...
receives the impulse initiated by the SA Node and slows the impulse before it reaches the ventricles, thereby keeping the atrias and ventricles from contracting simutaneously
48
function of the AV Bundle/Bundle of HIS...
increases impulse velocity as it travels through the ventricles
49
function of the purkinje fibers...
stimulates ventricles to contract
50
explain what occurs during atria systole/ventricular diastole
Semilunar valves close and cuspid valves open atrais contract forcing blood into ventricles
51
explain what occurs during atria diastole/ventricular systole
Semilunar valves open and cuspid valves close ventricles contract forcing blood into aorta and pulmonary valves
52
function of the vena cava...
receives blood from the body and returns it to the right atrium of the heart
53
function of the aorta...
receives blood from left ventricle and carries it to all parts of the body
54
function of the pulmonary artery...
receives blood from the right ventricle and carries it to the lungs
55
function of the pulmonary vein...
receives blood from the lungs and carries it to the left atrium
56
common name for SA Node
pacemaker
57
common name for AV Bundle
Bundle of His
58
define myocardial infarcation, explain why they occur, give related symptoms
Cause: oxygen deprivation to cardiac muscles cells causing a localized area of tissue death Reason: Plaque deposits along the walls of the coronary arteries Symptoms: pain in the mid-chest which travels up the neck out through the shoulders and arms, sometimes shortness of breath
59
insertion of a balloon, to open a coronary artery
angioplasty
60
insertion of a spring to open a coronary artery
stent
61
re-routing the blood flow around the blockage by graphing a vein taken from the leg or breast
coronary by-pass surgeryh
62
what is the cause of congestive heart failure and what occurs as it progresses in severity ?
ventricles pump unequal volumes of blood. if left ventricle pumps less and right ventricle pumps more, pulmonary edema results. (The lungs become more engorged with blood if right ventricle pumps less and left ventricle pumps more, fluid accumulates in legs, abdomen, and thoracic cavity.
63
heart rate more than 100 bpm
tachycardia
64
abnormally slow heart rate
bradycardia
65
an abnormal twitching of the ventricles leading to an infective heart beat
ventricular fibrillation
66
atrias suddenly begin to beat with a fast but feeble twitch
atrial fibrillation
67
cells of the AV node become diseased and cannot transmit adequate electrical impulses. atrias and ventricles begin beating independently
atriovenrtricular block
68
occurs when not enough blood is going to the heart muscle and may be brought on by an exercise and stress
angina pectoris
69
inflammation of the heart
pericarditis
70
top reading level for blood pressure
systolic blood pressure
71
bottom reading for blood pressure
diastolic blood pressure
72
normal blood pressure
120/80
73
pulse and pulse rate
is the alternate expansion nd recoil of an artery. 70-80 bpm
74
9 factors
1. smoking 2. high blood pressure 3. cholesterol 4. diabetes 5. overweght 6. sedentary lifestyle 7. family history 8. male 9. stress
