Ch. 18 Heart Anatomy JEOPARDY!
Coverings, Layers & Chambers Properties of Cardiac MusclePathway of Blood Heart Valves Properties of Cardiac Muscle RANDOM! 10 20 30 40 50 Final Jeopardy
Coverings, Layers & Chambers : 10The inner lining of the heart? Endocardium
Coverings, Layers & Chambers : 20The heart muscle. Myocardium
Coverings, Layers & Chambers : 30Serous layer covering the heart muscle. Epicardium 10 pt. BONUS: Another name for this layer. Visceral layer
Coverings, Layers & Chambers : 40The outermost layer of the serous pericardium. Parietal Layer
Coverings, Layers & Chambers : 50Which layer of the heart actually contracts? Myocardium
The left side of the heart pumps the same volume as the right.Pathway of Blood: 10 True or False: The left side of the heart pumps the same volume as the right. TRUE
L.V. pumps blood with greater pressure.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.
Blood flows where after being pumped out of the right ventricle?Pathway of Blood: 30 Blood flows where after being pumped out of the right ventricle? Lungs
Vessels that return blood to the heart.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
Prevents backflow into the left ventricleHeart Valves: 10 Prevents backflow into the left ventricle Aortic valve
Prevents backflow into the left atrium Mitral (bicuspid) vlaveHeart Valves: 20 Prevents backflow into the left atrium Mitral (bicuspid) vlave
FALSE – they both have chordae tendinaeHeart Valves: 30 TRUE or FALSE: The bicuspid valve has chordae tendinae but the tricuspid valve does not. FALSE – they both have chordae tendinae
Trabeculae carne are found in the ventricles and not in the atria.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: 10Compare Skeletal & Heart Muscle: Answer: Skeletal Muscle only, Cardiac Muscle only, or Both Has Striations Both
Properties of Cardiac Muscle: 20Compare Skeletal & Heart Muscle: Answer: Skeletal Muscle only, Cardiac Muscle only, or Both Contains self-excitable cells Cardiac Muscle only
Properties of Cardiac Muscle: 30Why 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 : 40What cell membrane junction allows the myocardium to function as a functional syncytium? Gap junctions
Properties of Cardiac Muscle: 50TRUE or FALSE: Cardiac muscle has more mitochondria and depends less on a continual supply of oxygen than does skeletal muscle. FALSE – O2 is essential
Where does the myocardium receive its blood supply from?RANDOM! : 10 Where does the myocardium receive its blood supply from? Coronary arteries
RANDOM! : 20 What structure is labeled with the star? Right Atrium
What valve is between the left atrium and the left ventricle? 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
What structures are labeled in the picture?RANDOM! : 50 What structures are labeled in the picture? Chordae tendinae
Final Jeopardy Name the laeled structure. Papillary muscle
