A&P Ch 22 Kuntzman Test

Enter the letter for the matching Answer
incorrect
1.
Atrial depolarization (contracting). Spread of impulse from SA node over atria
incorrect
2.
List some factors that affect heart rate
incorrect
3.
Ventricular depolarization (contracting). Spread of impulse through ventricles
incorrect
4.
List some of the benefits of regular exercise
incorrect
5.
Thick, striated, involuntary cardiac muscle tissue, and is the bulk of the heart. Muscle fibers swirl diagonally around the heart in bundles. It performs a pumping action.
incorrect
6.
How does the AV node allow more time for the atria to finish contracting?
incorrect
7.
Sequence of events in one heart beat
incorrect
8.
How is the heart related to your fist?
incorrect
9.
What chamber receives deoxygenated blood from the body?
incorrect
10.
How do baroreceptors function?
incorrect
11.
Where do you find serous fluid and what is its purpose for the heart?
incorrect
12.
Related to the stretching of the cardiac muscle cells in the atria
incorrect
13.
Which atrioventricular valve is on the right side of the heart?
incorrect
14.
A recording of the electrical changes that accompany each cardiac cycle (heartbeat)
incorrect
15.
Which chamber pumps deoxygenated blood to the lungs?
incorrect
16.
What blood vessels are taking blood from the myocardium?
incorrect
17.
Which atrioventricular valve is on the left side of the heart?
incorrect
18.
What do gasses, nutrients, & waste move through?
incorrect
19.
Explain how aerobic exercise benefits cardiac output, gas exchange, and metabolism
incorrect
20.
Which chamber of the heart has the thickest layer of myocardium?
A.
Epinephrine, norepinephrine, thyroid hormones, correct sodium - potassium - and calcium concentrations, emotions, age, gender, physical fitness, & temperature
B.
QRS complex
C.
Trucuspid
D.
Decreases anxiety & depression, controls weight, increases ability to dissolve blood clots by increasing fibrinolytic activity
E.
The human heart is approx. the size of a human fist
F.
The Frank-Starling law of the heart
G.
Aerobic exercise increases cardiac output & elevates metabolic rate
H.
Left ventricle
I.
Capillaries (during systemic circulation)
J.
Cardiac cycle
K.
Mitral/bicuspid
L.
The coronary veins
M.
Cells in the AV node conduct impulses more slowly which allows time for the atrium to finish contracting before the ventricle begins contracting
N.
Electrocardiogram
O.
Right ventricle
P.
Serous fluid is found in the pericardial cavity between the parietal & visceral layers. It prevents friction.
Q.
Right atrium
R.
Myocardium
S.
P wave
T.
Baroreceptors detect change in BP and send info to the cardiovascular center
Type the Answer that corresponds to the displayed Question.
incorrect
21.
Which valve is between the right ventricle & the pulmonary artery?
incorrect
22.
The flow of deoxygenated blood from the right ventricle to the lungs & the return of oxygenated blood from the lungs to the left atrium
incorrect
23.
Equals stroke volume (SV) x heart rate (HR)
incorrect
24.
Chronic or acute state that results when the heart is not capable of supply the oxygen demands of the body
incorrect
25.
Located in the ventricles of the heart. They attach to the cusps of the AV valves via the chordae tendinae & contract to prevent inversion or prolapse of these valves
incorrect
26.
An abnormal sound that consists of a flow noise that is heard before, between, or after the lubb-dupp or that may mask the normal sounds entirely
incorrect
27.
An anatomical region that includes all the visceral organs within the thoracic cavity except the lungs
incorrect
28.
The act of listening to sounds within the body
incorrect
29.
What is the volume of blood per minute pumped from the left ventricle into the aorta called?
incorrect
30.
Serous membrane lining the fibrous pericardium
