While the EM-J2 Series has no need to breath. This feature allows the unit to inhale and exhale like a human. This allows them to perform actions that need breath, eg. blow out a candle, blow up a balloon, whistle and even mouth to mouth resuscitation. The lungs also provide the ability to analyze the air. The lungs are self cleaning, and resemble the human lung.
While the unit has no need to to eat, this feature is available to allow the unit to interact better in social events. The tongue is replaced with one that has taste sensors. This is useful for an android who prepares food, the sensors can also perform a chemical scan looking for drugs and poisons. This allows the android to serve as a food taster. Unconsumed food and liquids are expelled in the normal human fashion.
The digestion system, can be used as an alternate power source. High calorie food that is consumed can be processed chemically to supply power. Food processing takes about 3-4 hours depending on other content in the food.
