The larger arteries are less then 1cm in diameter and are generally elastic and the smaller ones are 0.1-10mm and tend to be muscular.
Arteries have the largest diameter, then arterioles, and last, capillaries.
Arteries and veins are both in the same size range (which goes from more than an inch across to too small to be seen). Capillaries run about 4 microns - or half the diameter of a red blood cell (which must fold in order to get through them - thus the significance of sickle cell disease).
capillaries actually aren't arteries. arteries, veins, and capillaries are the major blood transport networks. arteries take blood away from the heart, veins take it back, and capillaries go between the two. capillaries are the smallest of these networks tho

Arteries do neither

arteries are the biggest and capilleries are small,but veins are the same size range with arteries
Arterioles are small diameter vessels that branch off of your arteries. They inevitably connect arteries to capillaries. You can find them pretty much anywhere in your body

Arteries are composed mainly of smooth muscle cells, also known as vascular smooth muscle. These muscle cells are responsible for regulating the diameter and constriction of the arteries, allowing for the control of blood flow and pressure. Additionally, arteries also have a layer of connective tissue and endothelial cells that line the inner surface.
Vasodilates them. Arteries increase in diameter size, this reduces the peripheral resistance on the blood. Not necessarily a good thing.
lowers resting heart rate increases ejection fraction increases diameter of coronary arteries
The autonomic nervous system regulates the heart rate and the diameter of the arteries. This is what determines blood pressure.
Your arteries are lined with smooth muscle tissues that regulate blood flow by contracting to decease the diameter of the arteries. This in turn causes the pressure and flow of blood to increase or stay the same if the heart is pumping faster. The hardening is cause by smooth muscle tissue becoming hard after constant stress. It is typical cause by being overweight because the heart and arteries have to work harder to pump blood all over the body.
The elasticity enables the arteries to change their diameter. Smaller means more pressure, larger means lower pressure.
These tubes (along with the heart) are known as the circulatory system, and they come in three varieties: arteries, veins, and capillaries. Arteries carry blood away from the heart, veins carry blood back to the heart, and capillaries are smaller diameter tubes connecting arteries and veins, through which blood interacts with tissues of the body.
