Remote and virtual labs represent a very important support in engineering teaching and can be used to improve the students learning process, for example of Biomedical Engineering courses, on topics such as the identification of models and control systems. This paper describes the demonstration of an online experiment, supported by a three-tank lab system, to model, simulate and monitoring a physiological process as the system of ingestion and excretion of a drug. A Web platform is used to interact with the remote and virtual lab, where students can visualize and obtain data in real time from the remote system.
