If a hole is placed in the interventricular septum, some blood will flow from the LV to RV because of the ____

A	higher pressure in RV than LV
B	lower pressure in RV than LV
C	more oxygenated blood in the LV
D	decreased oxygenated blood in the RV

Detailed explanation-1: -A ventricular septal defect happens during pregnancy if the wall that forms between the two ventricles does not fully develop, leaving a hole. A ventricular septal defect is one type of congenital heart defect. Congenital means present at birth.
