Vein vs. Artery
Carries blood toward the heart versus carries blood away from the heart.
The comparisoni
“The aorta is the biggest artery — arteries carry blood from the heart, veins carry blood back to the heart.”
The ruleii
¶
ARTERY = away. VEIN = back.
Arteries carry oxygenated blood from the heart (the pulmonary artery is the exception, carrying deoxygenated blood). Veins return blood to the heart. Arteries are thicker-walled to handle pressure; veins have valves.
Memory aidiii
Remember it like this
Artery exits. Vein returns.
