The liver package has been written as three discrete modules.
Module 1 A description of the structure of the liver illustrated by 3D animated graphics. The module contains a self-evaluation section.

Module 2 A detailed consideration of the functions of the liver which includes in-depth biochemical consideration of the following activities: a) Carbohydrate synthesis and metabolism. b) Protein synthesis and metabolism. c) Fat metabolism. d) Bile formation. e) Hormone inactivation. f) Liver storage functions. g) Drug metabolism. The module also contains a self-evaluation exercise.

Module 3 A brief introduction to common liver function tests and their significance in disease diagnosis. Attention is given to the following tests: Serum protein levels (albumin and globulin) Prothrombin time Gamma-GT levels Bilirubin levels Amino transferases Alkaline phosphatase Within each module, material is arranged in a series of pages, each dealing with a fundamental description or concept. Information of increasing complexity is presented as a sequence of layered windows within each page. Each layer is revealed by clicking on hot text or diagrams in the current screen display. The program design provides the student with control over the depth and complexity of study.
