What is the functional differences between arteries and veins?
Arteries carry blood away from the heart. Veins carry blood toward the heart.
The walls of both veins and arteries have three layers of tissues, but veins are much thinner and less elastic than arteries. Veins also have valves that help in the process of returning blood to the heart by preventing blood from flowing reverse. Arteries transport oxygenated blood away from the heart and veins transport de-oxygenated blood back towards the heart.
1) Arteries carry blood away from the heart while veins carry blood to the heart. 2) Arteries have thick and muscular walls (as they have to endure higher pressure) whereas veins have thin and slightly muscular walls. 3) Arteries have no valves, while veins have valves. 4) Arteries (in the post-fetal human) carry oxygenated blood except for the pulmonary arteries. Veins (in the post-fetal human) carry de-oxygenated blood except for the pulmonary veins.
1) Veins carry deoxygenated blood to the heart. Arteries carry oxygen rich blood away from the heart. 2) Veins are under very little pressure; arteries are under a lot of pressure. 3) The walls of arteries are made of muscle so as to regulate blood pressure and the diameter of the artery. Veins have little one way valves in them to keep the blood going in the right direction.
Arteries carry blood away from the hart, they have the highest blood pressure and amount of oxygen. (except for pulmonary arteries) Capillaries carry blood from arteries to veins. They are a single cell wide and exchange chemicals with nearby tissue. Veins carry blood towards the heart, and have the lowest amount of oxygen. (except for pulmonary veins)
There are 3 types of blood vessels: Arteries, Veins, and Capillaries. Arteries carry oxygenated blood to all the cells in the body. Veins carry deoxygenated blood back to the heart where it is pumped into the lungs. There is releases CO2 gas and picks up O2 and is pumped back into the heart where Arteries take it back to the rest of the body again. Capillaries are the smallest blood vessels connecting veins and arteries.
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…
