Question

Difference between Artery and Veins?​

Answer 1

ARTERIES :-

• it carries oxygenated blood from heart to all body parts. (Exception - pulmonary artery)

• arteries are thick walled an elastic.

• arteries have narrow lumen (space between them)

• blood pressure is high in arteries as compared to veins.

• arteries end in blood capillaries.

VEINS :-

• it carries deoxygenated blood from all body parts to the heart. (exception - pulmonary vein)

• veins are thin walled and less elastic.

• veins have broad lumen.

• blood pressure is low in veins as compared to arteries.

• veins start from blood capillaries.

Answer 2

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.
