Pathophysiology Cardiac Test 2

Front 1

The right side of the heart contains the right atrium and ventricle and is separated by which valve?

Back 1

tricuspid valve

Front 2

What is the primary function of the right side of the heart ?

Back 2

to recieve blood from the vascular system and to pump blood thru the lungs

Front 3

The left side of heart contains the left atrium and left ventricle, which valve separates the two

Back 3

mitral valve

Front 4

What is the primary function of the left side of the heart

Back 4

to receive oxygenated blood from the lungs and to pump blood thru the systemic circulation

Front 5

Both atriums are the ----- chambers and both ventricles are the ------ chambers

Back 5

receiving; ejecting

Front 6

which side of the heart has a lower pressure and why?

Back 6

the right side because it has a thinner myocardium

Front 7

what is the purpose of the cardiac valves?

Back 7

to maintain the directional flow of blood thru the <3 chambers

Front 8

which valves prevent backflow of blood from the ventricles into atrium DURING systole?

Back 8

mitral and tricuspid

Front 9

THIS valve is the outflow valve of the right ventricle into pulmonary circulation

Back 9

pulmonic valve

Front 10

This is the outflow valve of the left ventricle into the aorta

Back 10

Aortic valve

Front 11

The aortic and pulmonic valves prevent the backflow of blood from where?

Back 11

pulomonary artery and aortic arch into the ventricle during diastole

Front 12

the right side of the heart receives blood from the body and pumps it thru which artery to the lungs

Back 12

pulmonary artery

Front 13

the left side of the heart gets oxygenated blood from the lungs and pumps it thru WHAT to the body?

Back 13

Aorta

Front 14

Once blood is in the right ventricle where does it go next?

Back 14

blood is ejected thru pulmonic valve into pulmonary artery and to the lungs for 02

Front 15

oxygenated blood returns to the left atrium via What?

Back 15

pulmonary veins

Front 16

Once the blood go thru the mitral valve and into the lft ventricle what is next

Back 16

blood is ejected thru the aortic valve into the aortic arch and into systemic circulation

Front 17

what artery is the only one to carry unoxygenated blood

Back 17

pulmonary artery

Front 18

the only vein to in the circulatory system to carry oxygenated blood

Back 18

pulmonary vein

Front 19

what is the amount of blood ejected from the VENTRICLE

Back 19

stroke volume

Front 20

What is starlings law of the heart?

Back 20

the greater the cardiac muscle is stretched = more forceful the contraction= if an increased amount of blood flows into the heart = then the heart will increase the force of contraction and eject a larger # of blood

Front 21

stoke volume x HR

Back 21

cardiac output

Front 22

contractility

Back 22

the vigor or force to push blood forward; the ability of the myocardium to contract

Front 23

preload

Back 23

the filling of the ventricles at the end of diastole, the more the ventricles fill=more stretch=the greater the contraction force during systole - if there is a decrease in preload then contractility is decreased and CO

Front 24

afterload

Back 24

the pressure in the aorta that the ventricles must overcome in order to pump blood into systemic circulation; consrtict or dilate; good indicator of BP

Front 25

what provides the only source of oxygenated blood for the myocardium

Back 25

coronary arteries

Front 26

the left coronary artery divided into what

Back 26

anterior descending and circumflex arteries and supplies the left atrium/ventricles with 02

Front 27

what supplies the AV node of the conduction system with oxygen

Back 27

right coronary artery
