After travelling from the aorta, blood travels through peripheral arteries into smaller arteries called arterioles, and eventually to capillaries. Arterioles help in regulating blood pressure by the variable contraction of the smooth muscle of their walls, and deliver blood to the capillaries.
Arteries. Arteries carry blood which is full of oxygen away from the heart. Arteries have three layers of tissue-the outside and inside layers are made of a connective tissue which covers the muscular middle layer of smooth muscle, and elastic fibers. These tissues provide a smooth path for our blood to flow through.rteries. Arteries carry blood which is full of oxygen away from the heart.
