Are they first, second or third Heart Sounds?
Produced by the closure of the mitral and tricuspid valves in early systole
Occurs in early diastole, following the opening of the AV valve
Results from the closure of the aortic and pulmonic valves and therefore has aortic and pulmonic components
S3 = Occurs in early diastole, following the opening of the AV valve
S1 = Produced by the closure of the mitral and tricuspid valves in early systole
S2 = Results from the closure of the aortic and pulmonic valves and therefore has aortic and pulmonic components
TRUE or FALSE
Atherosclerosis plaques distribute homogeneously throughout the vasculature
False
Homogeneous means consisting of parts or elements that are all the same.

Valve function
Coronary anatomy
Myocardial perfusion
Ventricular chamber size
Myocardial perfusion
which is the process of blood flow to the heart
TRUE or FALSE
A major risk factor for atherosclerosis is abnormal circulating lipid levels.
TRUE
