Thick wall which is 8 layers thick. they help carry blood away from the heart.
They're high pressure blood vessels so they can transport more blood to the tissues at once using arterioles and capillaries

Arteries are muscular vessels that carry oxygenated blood from the heart to the rest of the body. The human body is divided into a few different types of arteries:
Pulmonary Arteries: Carry blood from the heart to the lungs
Systemic Arteries: (ie femoral) deliver to the body
When oxygenated blood leaves the heart, it travels amongst the biggest and highest pressure vessels called arteries. These arteries then send blood to lower pressure vessels such as arterioles, capillaries, and venules.
Blood pressure (hypertensive or hypotensive) effects not only the heart, but the tissues of the body downstream. Low blood pressure does not allow body tissues to be appropriately perfused with oxygen and causes the wall of the mydocardium (heart) to become weak from hypertrophy. High blood pressure creates a high internal pressure in the circulatory system which could expose weakened vessels to erupt, move plaques (emboli) into the pulmonary regions, etc.
