Right
R atrium receives venous blood from where?
Superior and inferior vena cava
What does pulmonary hypertension do to the heart?
causes elongation
Distribution of R coronary artery (RCA)?
R atrium, SA node, posterior R ventricle, AV node, bundle of his,
Distribution of L main coronary artery (LMCA)
Bifurcates within 2-10mm into the left anterior descending and circumflex arteries
Distribution of L anterior descending artery (LAD)
Anterior Left ventricle, ant. intraventricular septum and adjacent R ventricle, portion of both bundle branches, and often the proximal inferior portion of both ventricles and apex
Distribution of Circumflex artery (CX)
L atrium, lateral and inferior walls of the L ventricle, and sometimes serves as origin of the posterior descending
Distribution of posterior descending artery (PDA)
Posterior intraventricular septum, plus at least half of the inferior left ventricle
Systole (contraction) coronary aa squeezed causing?
Reduction in blood perfusion
Diastole (relaxation) coronary aa relaxed causing?
perfusing to myocardium
