(b) Difference between Arteries and Veins :

There are a number of differences between veins and arteries.

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.

I hope it will help you
