CVS 204 EXAM 1 2025 ACTUAL EXAM WITH VERIFIED QUESTIONS AND
ANSWERS GRADED A+
Blood Flow - ANSWER- SVC, IVC, Coronary sinus → RA → TV → RV → PV → MPA → Right and
left PA → Lungs → PV
→ LA → MV → LV → AOV → Aorta → Rest of body
Semilunar valves - ANSWER- pulmonic valve and aortic valve.
anatomy of aortic valve - ANSWER- -noncoronary cusp
-left coronary cusp
-right coronary cusp
what is behind each coronary cusp? - ANSWER- a pouch called the sinus of Valsalva
What is the sinus of Valsalva? - ANSWER- pouch like structure above the aortic valve form
which the coronary arteries arise
atrioventricular valves - ANSWER- Valves located between the atrial and ventricular chambers
on each side of the heart, prevent backflow into the atria when the ventricles are contracting.
(Tricuspid valve, Mitral/bicuspid valve)
Location of rudimentary valves - ANSWER- Eustachian valve - Inferior Vena Cava
Thebesian valve - Coronary Sinus
Eustachian valve - ANSWER- An embryologic remnant of the valve of the inferior vena cava
Thebesian valve - ANSWER- an embryologic remnant of the valve of the coronary sinus
, Layers of heart - ANSWER- ▪ Endocardium - inner layer
▪ Myocardium - middle layer, muscle layer
▪ Epicardium - outer layer
Pericardium - ANSWER- The pericardium contains 10-50 ml fluid within the pericardial space,
between the visceral and parietal layers
pericardial layers - ANSWER- Inner layer, serous pericardium.
outer layer, fibrous pericardium (helps to keep heart in the right place)
Muscles of the heart walls - ANSWER- Pectinate muscle, Papillary muscle,Trabeculae carneae
Papillary muscle - ANSWER- located in ventricles, attached to AV valve leaflets by chordae
tendineae, pull leaflets together and downward during ventricular contraction
Pectinate muscle - ANSWER- located in atria, form appendages/auricles
Trabeculae carneae - ANSWER- ridged rounded or irregular muscular columns which project
from the inner surface of the ventricles of the heart.
moderator band - ANSWER- muscular band of heart tissue that carries a portion of the right
bundle branch. located in the rv
crista supraventricularis - ANSWER- the thick muscle that separates the RVIT from the
RVOT
