Blood Flow Direction

Explain the Portal Venous System of blood flow

flows away from tdr from spleen, towards tdr up to splenic vein, portal confluence, now going away from tdr in splenic vein and continues on back towards tdr to the liver

Do veins or arteries compress?

veins compress

arteries do NOT

which way to veins and arteries flow?

veins always flow towards heart

arteries always flow away from heart

Difference b/w veins and arteries

-veins have thinner walls and lower pressure (can compress) and contain valves to prevent backflow of blood

-veins carry deoxygenated blood back to heart

-arteries have strong, elastic walls due to high pressure of blood they carry

-carry oxygenated blood away from heart to rest of body
