Veins are thin walled.

Blood flows under high pressure in the arteries.

Blood flows with low pressure in the veins.

Arteries carry oxygenated blood except pulmonary artery that carries deoxygenated blood.

Veins carry deoxygenated blood except pulmonary vein that carries oxygenated blood.

Arteries are generally red in colour since they carry pure, oxygenated blood.
