CVS 204 practice test,
What is perfusion? - ANSWER-The process of delivering blood to a tissue.
What factors can influence coronary artery flow? - ANSWER-Coronary artery disease, heart rate,
and diastolic pressures.
When does myocardial perfusion occur? - ANSWER-During diastole, the relaxation phase of the
cardiac cycle.
What happens during systole? - ANSWER-Aortic valve opens and aortic cusps cover coronary
artery opening.
What is the Sinus of Valsalva? - ANSWER-Location of coronary arteries.
,2|Page
How is systolic flow impaired? - ANSWER-Compression of small coronary branches in
contracting myocardium.
What happens during diastole? - ANSWER-Blood flows backward, filling the Sinuses of Valsalva.
What happens if the demand exceeds the supply? - ANSWER-Ischemia (inadequate blood
supply) will result.
What is the blood supply to the SA node? - ANSWER-RCA (70%) and LCx (25%)
From which artery can the SA nodal artery arise? - ANSWER-Left circumflex artery (LCx)
What is the composition of the muscular portion of the IVS? - ANSWER-Smooth muscle and
trabeculae carnae
What does the Intra-atrial Septum separate? - ANSWER-The right and left atria
What is the thin area in the intra-atrial septum called? - ANSWER-Fossa ovalis
What is the fossa ovalis? - ANSWER-The central portion of the IAS with a slight depression.
What does the fossa ovalis represent? - ANSWER-The closed foramen ovale of the fetal
circulation.
What does the main pulmonary artery carry? - ANSWER-Deoxygenated blood.
, 3|Page
What type of blood do most arteries carry? - ANSWER-Oxygenated blood.
What type of blood do pulmonary veins carry? - ANSWER-Oxygenated blood.
What type of blood do most veins carry? - ANSWER-Deoxygenated blood.
What are the oxygen requirements of the myocardium continuously matched by? - ANSWER-
Coronary arterial supply
What are the two main coronary arteries? - ANSWER-Right and left coronary arteries
Where do the right and left coronary arteries arise from? - ANSWER-Coronary cusp in the
sinuses of valsalva
Which arteries can perfuse the SA node? - ANSWER-RCA and LCx
What is the course of the right coronary artery? - ANSWER-Between the pulmonary artery and
right atrium and ventricle.
Where does the right coronary artery curve around? - ANSWER-The right border of the heart.
What are the two branches that the right coronary artery divides into? - ANSWER-Transverse
branch and descending branch.
What is the marginal branch? - ANSWER-A branch off the right coronary artery past the
bifurcation.
