What else can I help you with?
Is the diameter of the lumen larger in arteries or in capillaries?
Arteries have the largest diameter, then arterioles, and last, capillaries.
How does the diameter of arteries veins and capillaries compare in size?
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).
How thick is arteries?
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 branch into smaller vessels called?
Arteries branch into smaller vessels called arterioles. Arterioles are small diameter blood vessels that connect arteries to capillaries. They play a crucial role in regulating blood flow and blood pressure within the circulatory system.
The arteries that are also called distributing arteries are called?
muscular arteries
Is the diameter of the lumen larger in arteries or in capillaries?

How do veins arteries and capillaries compared in size within diameter?
arteries are the biggest and capilleries are small,but veins are the same size range with arteries
Where are arterioles located?
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

What type of muscles are your arteries?
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.
What does alcohol do to blood vessels?
Vasodilates them. Arteries increase in diameter size, this reduces the peripheral resistance on the blood. Not necessarily a good thing.
Explain three ways that exercise affects your heart?
lowers resting heart rate increases ejection fraction increases diameter of coronary arteries
What causes Hardening of the arteries?
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.
What is the effect of the elasticity of the arterie on arterial blood?
The elasticity enables the arteries to change their diameter. Smaller means more pressure, larger means lower pressure.
What are that's Carrie the blood around the body?
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.
