Pipes' Parts is a term used to describe the components of a pipe, such as the stem, which is the part that connects the bowl to the shank. The shank is the part of the pipe that extends from the bowl to the mouthpiece. The bowl is the part of the pipe where the tobacco is placed and lit. The mouthpiece is the part of the pipe that the smoker inhales through. The filter is an optional component of a pipe that helps to reduce the amount of tar and nicotine in the smoke. All of these components are necessary for a pipe to function properly.
