Describe how the structures of arteries are specialized for their particular function

The walls of the arteries are very thick. They are made up of thick elastic fibres and smooth muscles.

Arteries can be described as blood vessels which function to transport blood from the heart to other parts of the body. The blood that the heart pumps is high in pressure. Hence, the thick walls of the arteries are adapted to carry blood that has high pressure.

The other blood vessels do not have as thick vessels as the arteries.
