## Arteries

Arteries are blood vessels, the network of pathways through which the oxygenated blood travels away from the heart to various cells, tissues and organs of the human body.

• Arteries have thick walls and are situated superficially in comparison to other blood vessels.
• This is due to the fact that these blood vessels are responsible for transporting oxygenated blood across the body under high pressure.
• If the walls of these blood vessels are thinner, they will be weakened, resulting in blood loss from blood vessel rupture.
