Human heart has a complex embryological development process driven by genetic mechanisms that have successive and unitary progression in a global context.

The key takeaways are the main stages in heart development which are the primordial heart tube, cardiac looping, chamber septation, and development of valves ...

- because growth of the heart tube is faster than growth of the pericardial cavity and both ends of tube are hold by pericardium. Page 16. Bulboventricular loop.
