What are the differences between an artery and a vein?
Arteries carry blood away from the heart to the other parts of the body. Arteries also have thicker walls as the blood pressure is much higher having a closer proximity to the heart. Veins carry the blood back from the other areas of the body to the heart. Simply put, an artery carries blood out of the heart, and a vein carries blood into the heart.
Why are arteries muscular?
Arteries have to endure a much higher pressure, but the muscle wall surrounding the arteries are actually there to constrict and relax to help regulate blood pressure. Since blood pressure is one of your more important functions, the arteries are constantly constricting and relaxing to keep you BP at a reasonable level. They also play a role in blood shunting during your fight or flight response, but that tends to deal more with capillaries.In short the smooth muslce lining your arteries have various functions, but the key functions to their existence are :1.) Dealing with the higher pressure and not bursting by causing reinforcement to the pressure.2.) To constrict and diulate in order to help regulate blood pressure.There are other reasons for this but most fringe more on the molecular level or deal with secondary messengers, G proteins.

Why are the walls of arteries relatively thicker than those of the corresponding veins?
In general, the walls of arteries are thicker than those of veins. The tunic media in particular tends to be much heavier and contains substantially more smooth muscle and elastic tissue. This anatomical difference reflects a functional diffeerence in the 2 types of vessels. Arteries, which are closer to the pumping action of the heart, must be able to expand as an increased volume of blood flows off into the circulation during diastole. Their walls much be sufficiently stong and resilient to withstand such pressure fluctuations. The tunica media is thicker in the arteries mainly for maintaing blood pressure and continuous blood circulation.

Why do superchargers make so much noise?
A supercharger is constantly spoiled from pulleys even at idle. This additional air pressure must be released at idle to prevent excess idle surge. The air release typically is performed through a bypass valve (can be replaced with blow off valve) and the air escaping tends to create a whistle. The remaing air sounds from pressure release in between shift points are identical to the process/sounds in which a turbo releases excess air pressure. However, a turbo is exhaust driven and the excess surge in pressure does not occur at idle which is why they are much quieter when sitting still.
