Why is a motor engine and a body considered open systems?

Open systems can have mass and heat change with the surroundings. For an engine I think they are talking about fuel and air entering the body of the system and exhaust being released.

A motor engine has pipes leading out of the engine, making it an open system as it takes in and releases air. A human body has a nose and mouth which take in and release air as well. These are both open systems as there is an exchange between the internal system (the engine and the human body) and the universe (other system).

yes because they exchange matter and energy with its surroundings.
