Fetal Pig Anatomy: Urinary Bladder Blood Vessels

[pharaoh]

What blood vessels run on either side of the urinary bladder in the fetal pig?

is it umbilical vein or umbilical artery?

 

[Moonbear]

Umbilical arteries. Now, what you need to think through is how you'd have figured that out based on the anatomy if nobody told you the answer. What other vessel do the umbilical arteries branch off of? And what MAJOR vessel is that a branch from? And where does that major vessel enter/exit the heart? Whether a major vessel enters or exits the heart will tell you the direction of blood flow. Remember, Arterial blood flows Away from the heart and venous blood returns to the heart. When in doubt, trace the path back to the heart and see if it enters the atria or exits the ventricles.
