Is it true that the pulse can be felt on arteries but not on veins?

Yes, it's true. The beating of the heart only drives blood in the arteries. As the blood passes from the arteries to the capillaries and then to the veins, it ceases to be pumped by the heart, so no pulse can be felt. Blood in the veins returns to the heart because of the valves in the veins, and because of general muscular contractions in the body, rather than because of the heart.

∙ 9y agoThat is a good question! You get the pulsations felt in the arteries. When your heart contracts, you get the arteries dilated. When the heart relaxes, arteries contract and blood flow is maintained. This jerk of heart contraction is felt only in the arteries. The flow is slow and sustained in the capillaries and the veins. So you do not feel the pulsations there in these vessels. In addition the capillaries are too thin to give you any pulsations.

∙ 9y agoThe reason you can't feel your pulse in veins and capillaries but you can in arteries is because arteries are much larger and carry a larger amount of blood than veins and capillaries.

What do arteries and veins drain?
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.)
What Function Does The Heart Serve?
The heart PUMPS BLOOD through the arteries throughout your body. Veins take blood to your heart, arteries take blood away. some people think the heart pumps blood into your veins but that is NOT true. Your veins take the blood to your heart, the arteries take the blood away from your heart.
What are arterioles and venues?
== == Arterioles are very tiny arteries. In some areas of the body there are places where arteries and veins come together in tiny formations to swap oxygenated blood (in the arteries) for unoxygenated blood (in the veins). (As the veins get smaller they become capillaries, then caprioles.) The arteries are responsible for delivering blood with oxygen from the lungs to the rest of the body. Veins carry the "used blood" with no oxygen back to the heart where it passes into the lungs and picks up more oxygen and gets rid of the carbon dioxide that builds up as our bodies use the oxygen. The arterioles and caprioles come together to swap this blood. Well the above might be true but...... Arterioles are small arteries that deliver blood to the Capillaries. While Venules are small veins that are connected to the Capillaries.
Veins are located throughout the body and are responsible for carrying blood and oxygen away from the heart while arteries are responsible for carrying blood toward the heart to repeat the cycle?
true big boi
Are veins larger than arteries?
in general no. ---------------- Answer #2 Actually yes they are. You have to keep in mind to compare same-action veins with same-action arteries. You could easily compare a vein in the foot to an artery near the heart and the artery will obviously be larger. However compare a vein near the heart to an artery near the heart and the vein is actually larger in circumference. By thickness an Artery is technically larger because it has to have thicker walls in order to transport oxygenated blood at a high pressure. Veins have thinner walls(they transport the same amount of blood but at lower pressures than arteries) but are actually slightly larger than arteries in circumference. If you were to think of them like pipes, they would be ranked from largest to smallest as: -Vein(smaller veins are known as venules.) -Artery(smaller arteries are known as arterioles.) -Capillary(smallest of ALL blood transporting tubules.) Keep in mind Veins transport un-oxygenated blood back to the lungs for re-oxygenation while arteries carry oxygenated blood to the vital organs. Capillaries are like little side streets that help feed blood to the necessary parts of your body that aren't on the main highways. Varicose or Spider-veins are actually not veins but Capillaries that have risen up to the surface of the skin and often broken due to either trauma or pressure.
What do arteries and veins drain?
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.)
What statement is true of arteries?
Arteries carry blood with oxygen to the heart. Veins carry blood full of carbon dioxide to the lungs. Arteries have a thick wall. Veins have a thin wall. Arteries have no valves. Veins have valves.
Is it blood that runs in veins?
It is not true. Blood is also runs in arteries. Arteries take the blood throughout your body and veins take the blood back to your heart.
Are Veins for impure blood and arteries for pure blood is it correct?
yes it is true that arteries contain pure blood and veins contain impure blood
In the differences between veins and arteries it says veins 'rarely' pulsate 'mainly' carry deoxygenated blood one vein is different from the rest which one?
Viens do not have a pulse, but they do have valves that arteries do not. Most veins carry oxygenated blood toward the heart. The only exception is the pulmonary veins that carry oxygenated blood to the left atrium of the heart. The same is true for arteries. They carry oxygenated blood from the lungs to the rest of the body except the lungs. The pulmonary arteries are the only exception because they carry deoxygenated blood to the lungs.
Is ti true that arteries and veins both carry oxygenated blood only?
yes
Is it true that capillaries are the largest blood vessels?
No. There are three types of blood vessels. They are the arteries, veins, and capillaries. Arteries are the largest of the blood vessels. Then comes the veins and the smallest are the capillaries.
What Function Does The Heart Serve?
The heart PUMPS BLOOD through the arteries throughout your body. Veins take blood to your heart, arteries take blood away. some people think the heart pumps blood into your veins but that is NOT true. Your veins take the blood to your heart, the arteries take the blood away from your heart.
Most arteries carry deoxygenated blood true or flase?
Almost all arteries carry oxygenated blood while veins are the opposite. There is one difference and that is in the pulmonary circulation where this opposite.
True or false blood vessels that carry blood to the heart are called arteries?
False. Blood vessels that carry blood away from the heart are called arteries. Blood vessels that carry blood to the heart are called veins.

True or false Capillaries are where fresh blood is exchanged for old.?
I will tell you what a capillary is, but you should figure it out from there. A capillary is the tiny blood vessel that connects veins and arteries. The blood would go through the capillaries to reach one or the other. Remember: Arteries and veins each carry old or new blood. I can't remember what does what.
