1. Introduction. The human liver is the largest solid organ in the body and carries out a complex array of functions, ranging from metabolic homeostasis of nutrients and many hormones in the systemic circulation, to synthesis of virtually all plasma proteins, and serving as a nexus for myriad immune functions that balance innate and adaptive immunity and thus control tolerance and inflammation.

Operating characteristics: We assume that this is a continuous process, that is, that there is a continuous flow in and out of the tank. It would be a semicontin-uous process if, for example, there was an inlet flow with no outlet flow (if the tank was simply being filled). 6.

Mass flow controller - Wikipedia

A mass flow controller (MFC) is a device used to measure and control the flow of liquids and gases. A mass flow controller is designed and calibrated to control a specific type of liquid or gas at a particular range of flow rates. The MFC can be given a setpoint from 0 to of its full scale range but is typically operated in the 10 to 90% of full scale where the best accuracy is achieved.
