What is the difference between a blood vessel and veins?

Answer 1

capillaries are the fine branches of arteries or veins which supply blood to the bodies extremities, and veins are the thinner tubes carrying the de oxygenated blood back to the heart.

Answer 2

an arterym is a major blood vessel which carries blood away from the heart to the body, muscles, lungs, brain etc. A vein is the opposite; they carry blood towards the heart.

Capillaries are much smaller, usually one cell wide and are mainly used in the diffusion of gases and chemicals to and from cells.

Hope that helps, (and i hope its right, its a year or two since I've had to answer questions on the circulatory system)

Answer 3

Blood travels away from the heart through arteries and to the heart through the veins.

Veins are thin walled, with valves in them and with a wide lumen (central opening, the space that blood flows).

Arteries are thick, muscular walled with many different layers and with a narrow lumen.

In most cases, veins carry oxygen depleted blood (blue blood) from the tissues while arteries carry oxygen rich blood (red blood) to the tissues. However, the pulmonary artery carries oxygen depleted blood from the heart to the lungs. The pulmonary veins carry oxygen rich blood to the heart from the lungs.

Answer 4

Both are connected but play different role in our body circulatory system. These are the difference between veins and capillaries. # Capillaries are consist of single cell epithelium through which blood cells can pass while veins epithelium is bigger enough to hold blood cells in it. # Capillaries connect veins and arteries in body. # Veins always carry de-oxygenated blood except pulmonary vein which carries blood from lung to heart while capillaries carry both oxygenated and de-oxygenated blood depends on their end i.e. on arteries side they carry oxygenated blood and on veins site they carry de-oxygenated blood, here also process is reversed in case of pulmonary arteries and veins.

Answer 5

There is no difference between them veins are blood vessels, and blood vessels are veins.

Actually, there isn't a difference between the two terms, but a "vein" is a more specific type of "blood vessel." The human body contains about 60,000 - 100,000 miles of blood vessels, and around half of those are veins. The other half are arteries. Veins carry deoxygenated blood from the body to the heart and lungs to be re-oxygenated. The blood is then pumped out of the heart into the body through the arteries and into capillaries, which is where the oxygen is released into the tissues to assist in various metabolic exchanges and processes. A heart that is beating at 70 beats per minute can completely cycle the entire blood supply in the body in about a minute!

Answer 6

Veins- oxygen-poor blood that is returning to the heart

Arteries- oxygen-rich blood that is going to the cells

Capillaries- tubes that exchanges nutrients between those two^^

Answer 7

Veins- oxygen-poor blood that is returning to the heart

Arteries- oxygen-rich blood that is going to the cells

Capillaries- tubes that exchange nutrients between them two ^^
