Actually, I wasn't quite looking for that. I meant to ask for what says "All the blood, go to the digestive system"?
No, not all blood goes to the digestive system. Arteries ALWAYs carries blood AWAY from the heart and veins bring it back. Each cell in you body has a capillary that goes right next to it carrying blood with oxygen and nutrients and wastes away. That makes 50,000 miles of vessels.
capillaries
Capillary
Yes, the capillaries are the smallest kind of blood vessel, that facilitate the movement of substances (like oxygen and glucose) in and out of the blood through their very thin walls.
veins
The arteries, but to be exact, the aorta.
Capillaries are the smallest of all blood vessels.
red blood cells
The only blood vessels that contain valves are veins.
there is not a certain kind of vessel; all the vessels stretch.
Oxygenated blood
Platelets form to help control the blood loss.
Arteries (carries oxygenated blood), veins (carries deoxygenated blood) and capillaries (blood vessels connecting arteries to veins and vice versa).
