Question

Trace the flow of blood from the brain to the descending colon.  

Answer 1

ANSWER : The flow of blood from the brain to the descending Collon, before that it has to reach the heart. The blood from the brain comes through vein into the heart.

The blood in the brain goes to the basilar vein - vertebral vein - subclavian vein - Brachiocephalic vein - superior vena cava.

Then the blood from the superior vena cava goes to the right atrium - right ventricle (through the tricuspid valve) - pulmonary arteries- lungs - pulmonary veins- left atrium- left ventricle- ascending aorta - aortic arch - then it goes to descending aorta (because this aorta will supply the lower part of the body ) - inferior mesenteric artery - descending colon.
