The primitive ventricle is usually morphologically which ventricle?

Explanation:
In early heart development, the ventricle that originates from the primitive ventricular region of the heart tube ultimately forms the left ventricle. After looping, this primitive ventricle becomes the trabeculated part of the left ventricle, while the bulbus cordis mainly forms the right ventricle and the outflow tract. The septum primum and the endocardial cushions are involved in atrial septation and the AV canal, not in deriving the primitive ventricle.
