Blood vessels are categorized by function. The composition of the wall varies quantitatively among these subcategories. Arteries conduct blood away from the heart and have proportionately more smooth muscle and elastic tissue than veins of comparable size. Arteries are commonly sub-categorized into elastic arteries, muscular arteries, and arterioles.

Skeletal muscle has a remarkable plasticity to adapt and remodel in response to environmental cues, such as physical exercise. Endurance exercise stimulates improvements in muscle oxidative capacity,
