Primitive ventricle will become
Left ventricle
Primitive atria will become
Left and right atria
What are the inflow tracts of the sinus venosus?
Common cardinal veins (outermost)
Umbilical veins
Vitamins veins (innermost)
Sinus venosum gives rise to?
Visceral pericardium, primitive conduction system
What happens to the left horn that comes from the sinus venosus
Breaks down and also gives rise to coronary sinus
Common cardinal vein from right horn becomes?
