Arteries are high-pressure vessels. However, this pressure is not constant. As the heart pumps blood into the arteries, the pressure dramatically increases. They must stretch to accommodate this change, or risk rupturing.

Can veins and arteries stretch the same distance as the world?
In an average person, all the blood vessels, veins, arteries, and capillaries lined up one to the other can go around the world at least twice.
How does the pulsating blood pressure in the largest arteries relate to their structure?
It reveals their elasticity. When the heart contracts and forces blood into the large arteries near the heart, they stretch to accommodate the greater blood volume (systolic pressure). Then, as the blood continues on in the circuit, their walls recoil, keeping pressure on the blood which keeps it moving (diastolic pressure).
The arteries that are also called distributing arteries are called?
muscular arteries
Do arteries reproduce or does the human body make new arteries?
Arteries do neither
What are the vessels that take blood away from the heart?
The arteries
What do arteries have to be able to do when the heart pumps blood into them?
the answer is stretch
What kind of vessels stretch due to blood pressure?
arteries is the answer
What kind blood vessels stretch due to blood pressure?
arteries is the answer
Why do arteries?
Arteries are high-pressure vessels. However, this pressure is not constant. As the heart pumps blood into the arteries, the pressure dramatically increases. They must stretch to accommodate this change, or risk rupturing.
What is the substance found in tissues that stretch like arteries lungs skin?
Elastin and collagen.
What are stretch receptors?
These Receptors are present in Carotid and Aortic Arteries of Tetrapods and they have a vital role in regulation of Blood Pressure.
Can veins and arteries stretch the same distance as the world?
In an average person, all the blood vessels, veins, arteries, and capillaries lined up one to the other can go around the world at least twice.
Which experiment can be used to test that veins have morestrechable walls than arteries?
Bad experiment - veins don't hardly stretch (no elastin in walls), what they do is collapse.
How are the jobs of the vein and artery differant?
Arteries have thick, muscular walls that stretch when the heart pushes blood into it. Veins join many times to form larger and larger veins.

Why are muscle cells stretchy?
All blood vessels can stretch to an extent. However, arteries are most flexible because they have more muscular fibers in their walls.
What is the elasticity of the arteries?
Blood pressure varies all the time because of changes in heart beat, which becomes more energetic when it is influenced by adrenaline. Arteries need to have the capacity to expand so that they do not burst, at a time of unusually high blood pressure. So an elastic material is useful, since it has the capacity to stretch without breaking.
