Anatomy And Physiology 2

Front 1

The chamber of the heart with the thickest mycardium is the

Back 1

left ventricle

Front 2

The phase of heart contraction is called the

Back 2

systole

Front 3

The phase of heart relaxation is the

Back 3

diastole

Front 4

cardiac output equals

Back 4

stroke volume times heart rate

Front 5

In auscultation, the lubb represents closing of the SL valves and the dupp represents closing of the AV valves

Back 5

False

Front 6

The Frank-Starling law equalizes the output of the right and left ventricles and keeps the same volume of blood flowing to both the systemic and pulmonary circulations

Back 6

True

Front 7

What is the correct route of blood through the heart from the systemic circulation?

Back 7

Right atrium, tricuspid valve, right ventricle, pulmonary SL valve, left atrium, mitral valve, left ventricle, aortic SL valve

Front 8

What is the correct pathway for conduction of an action potential through the heart?

Back 8

SA node, AV node, AV bundle, bundle branches, purkinje fibers

Front 9

When would a murmur due to a stenosis of a semilunar valve be heard?

Back 9

Between S1 and S2 when the valve should be fully open but is not

Front 10

Left atrium collects oxygenated blood from the

Back 10

pulmonary circulation

Front 11

The right ventricle pumps deoxygenated blood to

Back 11

the lungs for oxygen

Front 12

Papillary Muscles

Back 12

contract and pull on and tighten chordae tendineae preventing the valve cups from everting

Front 13

Auricles

Back 13

Increase blood-holding capacity of the atria

Front 14

Chordae Tendineae

Back 14

tendonlike chords connected to the AV valve cusps

Front 15

The left ventricle pumps oxygenated blood to

Back 15

all body cells except the air sacs of the lungs
