This is because one side (the left) is for pumping blood from the heart to the lungs, where it receives oxygen. This blood is then pumped to the rest of the body through the other side of the heart (right) where the oxygen nourishes the rest of the body. This blood then returns to the left side of the heart, to be pumped to the lungs to receive more oxygen and so on.
Note that each side of the heart (right and left) also contains two chambers - an atrium and a ventricle (so the heart is made of four chambers in total). Blood entering the heart passes into the atrium, then on to the ventricle, and then on out of the heart.
There are veins on both sides.
The superior vena cava carries blood from the upper half of the body to the heart, while the inferior vena cava carries blood from the lower half of the body to the heart, both entering into the right atrium, these are both veins.
They both carry blood in them, but veins take blood to the heart, artiries take blood from the heart, usually!
I think its both
Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart. Veins are less muscular than arteries and are often closer to the skin.
Blood flows through both Well, for one thing, veins and arteries both carry blood through the body and they both lead from the heart too. The only difference is that the arteries, are fatter than veins. Also, i think that if you pop an artery or poke a hole in your artery, then your blood comes spewing out like a fountain! The arteries take blood from the heart, while the veins, bring blood too the heart.
Veins do carry blood to the heart while arteries carry blood away from the heart. Here is a way to remember it: Arteries=Away ( they both have A's in it)
Through both! The pulmonary veins carry oxygenated blood to the heart and then arteries carry it from the heart to the body as a whole. Veins return de-oxygenated blood to the heart.

Both veins and arteries. The contracting muscles on all sides of the vessels squeeze the blood along in the dire tion it is travelling, either away from (arteries) or back to (veins) the heart. This helps the heart so that it doesn't have to do all the hard work itself. In other words exercise is good for your heart. Medicine calls it the skeletal muscle pump.
veinsAnswerArteries are the blood vessels that carry blood away from the heart, not veins. Veins are the blood vessels that carry blood towards the heart. The only exceptions being the pulmonary and umbilical veins, both of which carry oxygenated blood.
