26
What is the top center abdominal-pelvic region?
Epigastric region
27
What is the top right abdominal-pelvic region?
The right hypochondriac region
28
What are the middle left and right abdominal-pelvic region?
Right and left lumbar region
29
What is the center abdominal-pelvic region?
Umbilical region
30
What is the bottom right and left abdominal-pelvic region?
Right and left iliac region
31
What is the bottom middle abdominal-pelvic region?
Hypogastric region
32
Where is the heart location?
Left of the midline in the thoracic cavity
33
What are the two layers of the pericardium?
Fibrous and serous pericardium
34
What is the blow flow cycle?
Deoxygenated blood goes in the superior and inferior vena cava, into right atrium, into the right ventricle, through the pulmonary trunk through the left and right pulmonary artery. The oxygenated blood goes into the pulmonary veins into the left atrium, to the left ventricle, which goes into the aorta.
35
What is the right AV valve called?
Triscuspid
36
What is the left AV valve called?
Mitral valve
37
What are the coords connecting the papillary muscle and the right ventricle?
Tendinous cords
38
What are the two major arteries?
The right and left coronary arteries
39
What is the artery on the right more in the center?
Posterior descending artery
40
What splits off the right coronary artery?
Right marginal artery
41
What is the artery right under the coronary artery?
The left circumflex artery
42
What left artery is more on the back?
The left marginal artery
43
What left artery is more towards the center?
Left anterior descending artery
44
What vein is under the superior vena cava?
The anterior cardiac vein
45
What is the lowest under the superior vena cava?
Small cardiac vein
46
What is under the left atrium?
The great cardiac vein
47
What connects most of the veins?
The coronary sinus
48
What vein runs down the center?
The middle cardiac vein
49
What does systole mean?
Contraction
50
What does diastole mean?
Relaxation
51
What is the strove volume formula?
SV = End-diastolic volume - End-systolic volume
52
What is the formula for CO?
CO= heart rate (HR) x Stroke volume (SV)
53
What is the cardiac resting potential?
-90mV maintained by K+ leakage
54
What is depolarization caused by?
Influx of Na+ through fast channels at 0 then influx of Ca2+ at -40
55
What happens during the resting phase?
K+ rectifier opens and Ca and Na close
56
What happens during depolarization?
Na open and Ca open
57
What happens during early repolarization?
K efflux and Na close
58
What happens during plateau phase?
K and Ca equilibrium
59
What happens during repolarization?
Ca close and K influx
60
What is the conduction pathway?
SA node - AV node - AV bundle - left and right bundle branch - purkinje fibers
61
What is the output of an ECG machine called?
Electrocardium
62
What happens during the p wave?
Depolarization of atria
63
What happens during the PR interval?
Delay of AV node to allow filling of ventricle
64
What happens during the QRS complex?
Depolarization of ventricles
65
What covers the atria repolarization
The QRS complex
66
What happens during the ST segment?
Beginning of ventricle repolarization, should be flat
67
What happens during the t wave?
Ventricular repolarization
68
What is the flat bottom part of the stethoscope?
The diaphragm
69
What is the round bottom part of the stethoscope?
The bell
70
What is the long part of the stethoscope called?
Tubing
71
What is the bent silver piece on the stethoscope?
Binaural spring
72
What are the two silver pieces that go up to your ears called?
Binaural
73
What are the two black tips on the stethoscope called?
Eartips
74
What’s is the first sound of the heart?
The AV valve closing
75
What is the second sound of the heart?
The semilunar valves closing
76
