True or False: Tracers can traverse through the model and their distance can be tracked.

The assertion that tracers can traverse through the model and their distance can be tracked is indeed true. In tissue engineering and related fields, tracers are commonly used to study the diffusion and movement of substances within engineered tissues or biological systems. The ability of tracers to move through a model provides valuable insights into the porosity, permeability, and overall structure of the tissue being studied.

Tracers can be various types of particles, dyes, or molecules that are added to a system to visualize and quantify the transport phenomena within the engineered tissue. The tracking of their distance allows researchers to assess how effectively nutrients, drugs, or cells can migrate through the tissue model, which is crucial for evaluating the performance of tissue constructs and understanding how they might behave in a living organism.

Thus, the correct choice underscores the fundamental role of tracers in assessing and validating the properties of models in tissue engineering.
