Coverings, Layers & Chambers : 10
The inner lining of the heart?
Endocardium
Coverings, Layers & Chambers : 20
The heart muscle.Myocardium
Coverings, Layers & Chambers : 30
Serous layer covering the heart muscle.
Epicardium10 pt. BONUS: Another name for
this layer.Visceral layer
Coverings, Layers & Chambers : 40
The outermost layer of the serous pericardium.
Parietal Layer
Coverings, Layers & Chambers : 50
Which layer of the heart actually contracts?
Myocardium
Pathway of Blood: 10
True or False:The left side of the heart pumps the same volume
as the right.TRUE
Pathway of Blood: 20
Why is the left ventricular wall thicker than the right
wall of the heart?L.V. pumps blood with
greater pressure.
Pathway of Blood: 30
Blood flows where after being pumped out of the
right ventricle?Lungs
Pathway of Blood: 40
Vessels that return blood to the heart.
Pulmonary veins
Pathway of Blood : 50
Cardiac veins return blood to this location before the
blood enters the right atrium.
Coronary Sinus
Heart Valves: 10
Prevents backflow into the left ventricleAortic valve
Heart Valves: 20
Prevents backflow into the left atrium
Mitral (bicuspid) vlave
Heart Valves: 30
TRUE or FALSE:The bicuspid valve has chordae tendinae but the tricuspid valve
does not.FALSE – they both have
chordae tendinae
Heart Valves: 40
TRUE or FALSE:Trabeculae carne are found in the ventricles
and not in the atria.TRUE
Heart Valves: 50
The AV valves are supported by these structures so they do not blow back up into the
atria during ventricular contraction.
Chordae tendineae
Properties of Cardiac Muscle: 10
Compare Skeletal & Heart Muscle:
Answer: Skeletal Muscle only, Cardiac Muscle only, or Both
Has StriationsBoth
Properties of Cardiac Muscle: 20
Compare Skeletal & Heart Muscle:
Answer: Skeletal Muscle only, Cardiac Muscle only, or BothContains self-excitable cells
Cardiac Muscle only
Properties of Cardiac Muscle: 30
Why is the heart a functional syncytium?
The heart contracts as a unit (all or none) or it
doesn’t contract at all.
Properties of Cardiac Muscle : 40
What cell membrane junction allows the
myocardium to function as a functional syncytium?
Gap junctions
Properties of Cardiac Muscle: 50
TRUE or FALSE:Cardiac muscle has more mitochondria and depends
less on a continual supply of oxygen than does skeletal
muscle.FALSE – O2 is essential
RANDOM! : 10
Where does the myocardium receive its
blood supply from?Coronary arteries
RANDOM! : 20
What structure is labeled with the star?
Right Atrium
RANDOM! : 30
What valve is between the left atrium and the left
ventricle?Mitral (bicuspid) valve
RANDOM! : 40
What is the chamber that receives blood from the
superior and inferior vena cava?
Right atrium
RANDOM! : 50
What structures
are labeled in the picture?Chordae tendinae
Final Jeopardy
Name the laeled structure.
Papillary muscle
