KHP 205 Ch. 13 The Heart

The outermost layer of the heart wall is called the:

• epicardium

• myocardium

• endocardium

• septum

The part of the heart capable of generating the largest force is the

• right atrium

• right ventricle

• left atrium

• left ventricle

The heart chamber that receives blood from the lungs is the

• right atrium

• right ventricle

• left atrium

• left ventricle

The left ventricle receives blood from the

• pulmonary arteries

• right ventricle

• left atrium

• pulmonary veins

Threads that attach the valve flaps to the ventricle walls are called

• chordae tendineae

• ductus arteriosus

• stenoses

• stents

The valve that prevents blood from reentering the left ventricle is the

• mitral valve

• tricuspid valve

• pulonary semilunar valve

• aortic semilunar valve

The semilunar valves are the

• mitral and bicuspid

• aortic and mitral

• pulmonary and bicuspid

• aortic and pulmonary

The coronary sinus

• supplies blood to the heart

• supplies blood to the head

• drains into the superior vena cava

• collects blood from the myocardium

The volume of blood ejected from each ventricle with each beat is the

• cardiac output

• stroke volume

• heart rate

• cardiac cycle

The atrioventricular valves are closed during the entire period of

• ventricular systole

• atrial systole

• the cardiac cycle

• atrial diastole
