Aortic sac Truncus arteriosus Bulbus cordis Primordial ventricle Primodial atrium Sinus vinosus |
|
|
What does each form in the developed heart? Aortic sac Truncus arteriosus Bulbus cordis Primordial ventricle Primodial atrium Sinus vinosus |
Aortic sac = Truncus arteriosus = pulmonary trunk and ascending aorta Bulbus cordis = pulmonary trunk and ascending aorta Primordial ventricle = right and left ventricle (muscular part) Primodial atrium = right and left atria (muscular part) Sinus vinosus = coronary sinus and sinus venarum |

Inflow = caudal Outflow = cranial |
|
|
How many inflow veins are there, and which are they? |
6 inflow veins 2 common cardinal veins 2 umbilical veins 2 vitelline veins |
|
|
Where do the inflow veins dump into? What does this become? |
The sinus vinosus Becomes the coronary sinus |
|
|
Common cardinal veins |
Receive deoxygenated blood from the body through an anterior and posterior cardinals |
