100
The outermost layer of the serous pericardium.
What is the Parietal Layer?
100
Where myocardium receives its blood supply.
What is coronary arteries?
100
Prevents backflow into the left ventricle.
What is Aortic valve?
100
3 tunics
What is the number of layers that make up the blood vessels?
100
The layer of the heart that actually contracts.
What is myocardium?
200
Serous layer covering heart muscle.
What is the Epicardium?
200
True or False....The left side of the heart pumps more blood than the right side.
What is false? They pump the same volume.
200
Prevents backflow into the left atrium.
What is Mitral valve?
200
0.8 seconds
What is the cardiac cycle when the heart is beating at 75 bpm?
200
It is easy to visually discern the left and right ventricles when viewing a dissected heart.
What is noticing the thickness of the ventricular walls?
300
Purkinje fibers
What is the network found in the ventricular myocardium?
300
(T or F) The bicuspid valve has "heart strings" but the tricuspid does not.
What is false. Both valves have chordae tendineae.
300
Prevents backflow into the right ventricle.
What is Pulmonary valves.
300
Angina pectoris
What is the pain associated with deficient blood delivery to the heart caused by transient spasms of coronary arteries?
300
(T or F) The pulmonary trunk receives blood during right ventricular systole.
What is true?
400
The inner lining of the heart.
What is Endocardium?
400
(T or F) The "lub" sounds of the heart provide information about the function of the heart's pulmonary and aortic valves.
What is false? The "lub" is when the blood flows from atrium to ventricle.
400
AV valve with two flaps.
What is Mitral valve (bicuspid valve)?
400
A lowering of blood pressure due to change in cardiac output.
