The Majority of Right Atrial Filling Occurs During What Phase of Respiration? - ANS-
Inspiration; Inspiration drops the pressure in the chest allowing an increase in flow
from the Vena Cavaa into the Right Atrium

What Should Not Empty into the Coronary Sinus - ANS-SVC
Defined as a part of the Fetal Circulation that connects the Pulmonary Artery and the
Descending Aorta - ANS-Ductus Arteriosus
Coronary Vessels Courses through the Anterior Intraventricular Groove? - ANS-LAD
Middle Coronary Artery Courses Through - ANS-Posterior Interventricular Groove
