The Valves
$100 Question
This valve lies between the right atrium
and right ventricle (tricuspid valve)
ANSWER
BACK TO GAME
The Valves
$200 Question
This valve lies between the right ventricle
and the pulmonary trunk (pulmonary
semilunar valve)
ANSWER
BACK TO GAME
The Valves:
$300 Question
This valves prevents back flow into the left
atrium (mitral/bicuspid valve)
ANSWER
BACK TO GAME
The Valves
$400 Question
This valve prevents backflow into the left
ventricle. (aortic semilunar valve)
ANSWER
BACK TO GAME
The Valve
$500 Question
The bicuspid valve is also known as this
valve? (mitral)
ANSWER
BACK TO GAME
The Anatomy:
$100 Question
These muscles attach the chordae
tendineae to the AV valves. (papillary
muscles)
ANSWER
BACK TO GAME
The Anatomy
$200 Question
This inner layer of the heart is the
_(endocardium)____
ANSWER
BACK TO GAME
The Anatomy
$300 Question
The layer covering the heart muscle is the
__(epicardium)________________
ANSWER
BACK TO GAME
The Anatomy
$400 Question
This area of the heart is known as the
“pacemaker” of the heart. (sinoatrial node
or SA node)
ANSWER
BACK TO GAME
The Anatomy
$500 Question
The major part of the heart muscle is
called the (myocardium)
ANSWER
BACK TO GAME
The Flow
$100 Question
Blood flows from the right ventricle to this
area of the body through these (to the
lungs through the pulmonary arteries)
ANSWER
BACK TO GAME
The Flow
$200 Question
Blood flows from the atriums to the
ventricles through these (valves)
ANSWER
BACK TO GAME
The Flow
$300 Question
Blood loss will result in the lowering of
(blood pressure)because this is reduced?
(Blood volume)
ANSWER
BACK TO GAME
The Flow:
$400 Question
Blood flows from this heart section through
this valve into this major artery (left
ventricle through the aortic semilunar valve
to the aorta)
ANSWER
BACK TO GAME
The Flow:
$500 Question
Oxygenated blood returns to the heart
from the lungs through these (pulmonary
veins)
ANSWER
BACK TO GAME
The Volume
$100 Question
Normal cardiac output is _70___ml/beat
ANSWER
BACK TO GAME
The Volume
$200 Question
This period of time is different in cardiac
muscles and skeletal muscles in order to
prevent tetanic contractions which could
stop the beating of the heart (refractory
period)
ANSWER
BACK TO GAME
The Volume
$300 Question
A loss of blood supply to the heart would
result in this deprivation (oxygen)
ANSWER
BACK TO GAME
The Volume
$400 Question
This kind of heart rate increases the stroke
volume, the end diastolic volume and
therefore force of contraction (slow heart
beat)
ANSWER
BACK TO GAME
The Volume
$500 Question
This ion could cause the pacemaker cells
to increase reach threshold more quickly
and increase the heart rate. (Na+)
ANSWER
BACK TO GAME
The Technology
$100 Question
The P wave of the ECG indicates
depolarization of this heart area. (atrial
depolarization)
ANSWER
BACK TO GAME
The Technology
$200 Question
The QRS represents depolarization of this
heart area (ventricular depolarization)
ANSWER
BACK TO GAME
The Technology
$300 Question
The T wave of an ECG represents this?
(ventricular repolarization)
ANSWER
BACK TO GAME
The Technology
$400 Question
The term used to “listen” to the closing of
the valves is called? (auscultate)
ANSWER
BACK TO GAME
The Technology
$500 Question
This instrument is used to auscultate the
heart. (stethoscope)
ANSWER
BACK TO GAME

Heart pain caused by a coronary arterial
spasm is called ___angina pectoris, while
heart failure due to a mild blow to the
chest is called commotio cordis
