Explanation:
Detailed explanation-1: -Arteries carry blood away from the heart, and veins carry blood towards the heart. With the exception of pulmonary blood vessels, arteries carry oxygenated blood and veins carry deoxygenated blood. Arteries have thick walls with muscle tissue. Veins have thinner walls and use valves to keep your blood flowing.
Detailed explanation-2: -The primary reason for taking blood from an artery rather than a vein is to measure blood gases. Because arterial blood is oxygenated blood flowing directly from the heart, analysis of arterial blood can determine the chemistry of the blood before it is used by the tissues.
