Typically, blood is taken from veins instead of arteries. Arteries are the biggest passageways for blood in the body, and a person could easily bleed out if an artery was punctured. Conversely, arterioles are too small for a needle to go through. So, veins are the only tubes from which blood can be safely and easily drawn.

If you place a needle into an artery, you have a higher chance of causing a fatal bleeding than if you do the same into a vein. Also, since the walls of veins are thinner, it is easier to slide a needle into the vein.

It is drawn from a vein because: that is the system blood uses to travel around the body.
The reasons that a medic may take a particular sample from a particular site is best left to the medics.

Why are arteries usually drawn as red in diagrams while veins are drawn as blue?
To symbolize that arteries carry blood that's rich in oxygen while veins carry blood that's low on oxygen.
Name three blood vessels?
the three blood vessels are the Veins capillaries Arteries the arteries.
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 is the difference between the blood in the arteries and the blood in the veins?
Veins do not pulsate Arteries pulsate Veins can easily collapse Arteries do not collapse (except in shock) Veins contain valves Blood pressure is low in the veins and higher in the arteries
What are the kinds of blood vessels?
Capillaries, arteries, and veins are the kinds of blood vessels.
What does the blood travel through?
arteries and veins
What is the name of the blood vessel which takes blood from the body?
Typically, it is drawn from the antecubital vein, in the arm. It can be drawn from other veins, as well, including dorsal veins in the hands and feet, and from ports inserted into larger veins, for instance.
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.
What returns blood the veins or the arteries?
The veins.
What two ways are veins structurally different from arteries?
blood travels away from the heart through arteries and blood travels to the heart through the veins
What is the major difference between arteries and veins?
Arteries carry blood away from the heart. Veins return blood to the heart.
Name the 3 type of blood vessels in the body?
The 3 types of blood vessels are: 1. veins, which carry blood to the heart; 2. capillaries, which connect veins and arteries, and 3. arteries, which carry blood away from the heart.
