Class Intestine

java.lang.Object
  metab.Intestine

All Implemented Interfaces:

java.io.Serializable

public class Intestine

extends java.lang.Object

implements java.io.Serializable

The Intestine class simulates the Small Intestine compartment in the Compartmental model. The only actual job that the small intestine accomplishes in relation to the metabolism of ethanol is transport the ethanol from the small intestine to the blood via the villi contained in the intestinal wall. No ethanol is actually metabolized in the small intestine, but it is instead a factor that just delays transport to the LeanBodyMass. The user must handle the transport of the ethanol and liquid between other compartments by using the addLiquid and addContents methods for each compartment. To implement, all that is required is the amount of ethanol (g), and the total liquid volume (L). An optional extra description (label) may be included, but is not required for the class to function properly.
