The sequence of events in heart looping
- The heart begins as a straight tube then bends ventrally.
- Rotation brings the bulge of the ventral bend (predominantly the bulbus cordis and ventricle) to the right, forming a C-shaped loop.
- As the atrium is brought cranially, the poles of the heart converge. The heart now appears as an S-shape, with the first bend in the S between the bulbus cordis and ventricle and the second bend between the atrium and sinus venosus.
- The bulbus cordis and arterial trunk move ventral to the atrium to form the later outflow tract. The atrium now lies superior to the ventricle.
