Differentiate between veins and arteries.
Understand the Problem
The question is asking for a comparison between veins and arteries, focusing on their differences in structure, function, and role within the circulatory system.
Answer
Veins carry blood toward the heart, have thinner walls, and lower pressure; arteries carry blood away from the heart, have thicker, more elastic walls, and higher pressure.
The final answer is that veins and arteries have several key differences related to structure, function, and location in the circulatory system.

More Information
Veins typically have valves to prevent backflow of blood, while arteries do not need valves due to higher pressure from heartbeats. Veins appear bluish through the skin, whereas arteries tend to be deeper and thus less visible.
Tips
One common mistake is to assume that all arteries carry oxygenated blood and all veins carry deoxygenated blood. In fact, the pulmonary artery carries deoxygenated blood from the heart to the lungs, and the pulmonary veins carry oxygenated blood from the lungs to the heart.
