The material that allows arteries and veins to change size is smooth muscle tissue. This type of muscle is found in the walls of blood vessels and can contract or relax to regulate the diameter of the vessels, thereby controlling blood flow and pressure. Additionally, the elastic fibers in the vessel walls also contribute to their ability to stretch and recoil, further aiding in size adjustment.
Cellulose is what surronds veins and arteries.
Lymph tissue
No, it is carried through the veins.
the three blood vessels are the Veins capillaries Arteries the arteries.
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
Veins do not pulsate Arteries pulsate Veins can easily collapse Arteries do not collapse (except in shock) Veins contain valves Blood pressure is low in the veins and higher in the arteries
Thee difference between muscle in veins and arteries is that muscles of arteries are thicker compared to those of veins.
blood travels away from the heart through arteries and blood travels to the heart through the veins
The tunica media is thicker in arteries than in veins.
arteries and veins
if you attach your veins and arteries together,it will go around the world
Arteries, capillaries, & veins.
