Answer 2

Answer :-

First of all, what are arteries and veins ?

Ans - Veins and arteries are the structures which form extensive channels inside the body to carry blood from the heart to various parts of the body and vice-versa.

Arteries :-

• The arteries carry oxygenated blood from the heart to various parts of the body.

• The arteries consist of thick walls.

• Blood flows under high pressure through the arteries.

• Arteries are deeply located in the body.

• Arteries are highly muscular.

Veins :-

• Veins carry de-oxygenated blood from the various parts of the body to the heart.

• The veins consist of thin walls.

• Blood flows under low pressure inside the veins.

• Veins are less deeply located in the body.

• Veins are superficially muscular.

Exceptions :-

The pulmonary vein carries oxygenated blood from the lungs to the heart.

The pulmonary artery carries de-oxygenated blood from the heart to the lungs.
