There is an important need for comprehensive There is an important need for comprehensive courses related to Biotransport to be offered at the courses related to Biotransport to be offered at the undergraduate and graduate levels in US undergraduate and graduate levels in US Universities.Universities.
These courses must emphasize both theory and These courses must emphasize both theory and applications, motivating students to carry out applications, motivating students to carry out careful experimentation which will validate what careful experimentation which will validate what they have learned in theory.they have learned in theory.
At present, although there are many different At present, although there are many different descriptions of courses related to biotransport that descriptions of courses related to biotransport that are available in catalogues of various departments, are available in catalogues of various departments, it is clear that a systematic approach is needed to it is clear that a systematic approach is needed to develop a formally comprehensive set of guidelines develop a formally comprehensive set of guidelines and course material descriptions that will be useful and course material descriptions that will be useful for the student body at large.for the student body at large.
AbstractAbstract
As a part of this discussion, a comprehensive As a part of this discussion, a comprehensive model course description is displayed in the model course description is displayed in the following.following.
This model will apply to undergraduate and This model will apply to undergraduate and graduate level courses; the degree of detail, graduate level courses; the degree of detail, rigor, and emphasis will vary depending on the rigor, and emphasis will vary depending on the level at which the course is offered.level at which the course is offered.

Introduction to BiotransportIntroduction to Biotransport
The role of transport processes in biological The role of transport processes in biological systems; biological system description must systems; biological system description must include precise concepts both from biology include precise concepts both from biology and from engineering. What constitutes a and from engineering. What constitutes a biological system model must be addressed.biological system model must be addressed.
Multiphase (both on the basis of material Multiphase (both on the basis of material composition and thermodynamically distinct composition and thermodynamically distinct phases) are common in biotransport.phases) are common in biotransport.
Diffusion, convection, binding interactions, Diffusion, convection, binding interactions, and cellular transport are the most common and cellular transport are the most common types and must be clearly discussed.types and must be clearly discussed.
