Answer:
Veins:
carry blood from the tissues of the body back to the heart
are usually positioned closer beneath the surface of the skin
are less muscular than arteries, but contain valves to help keep blood flowing in the right direction, usually toward the heart
would collapse if blood flow stops.
Arteries:
carry blood away from the heart to the tissues of the body
are usually positioned deeper within the body
are more muscular than veins, which helps in transporting blood that is full of oxygen efficiently to the tissues
would generally remain open if blood flow stopped, due to their thick muscular layer.
