This is because blood from heart exerts high pressure on the artery walls. To withstand this pressure they are made very strong and elastic. This is by nature and not man-made

The correct answer is:
The walls of an artery are muscular because they have to maintain some pressure to keep the blood flowing at a steady rate. The artery is delivering oxygen to the cells, and this needs to be precisely regulated.
The vein is mainly returning blood to the heart. It may be carrying food to the cells and waste to the kidneys and lungs; but this doesn't require as much precision in terms of speed. Not needing the muscles, the walls are thinner.
