Part A:
See the "Getting to know the Pressure Cooker: Parts" chart.

Part B:
See the instruction manual of your classroom pressure cooker for specifics on care and cleaning. Generally the sealing ring groove should be cleaned periodically and a light coating of cooking oil should be applied to the underside of the pressure cooker body lugs. The sealing ring and overpressure plug should be replaced at least every two years (see instruction manual). The vent pipe should be cleaned with a small brush or pipe cleaner. For proper storage, the cover should be inverted on the pressure cooker body with the sealing ring out of the groove. Storing a pressure cooker with the cover locked on may cause unpleasant odors and may deform the sealing ring.
