Why study rat's internal and external structures? "For the pure sake of learning new things", could be one answer. We need to study external and internal structures of a rat in order to acquire correct knowledge about rats.
Now for a selfish answer. Since human beings are so much like rats, when we know something more about rats, we nearly always have learned something about ourselves.
More so in the past, but still today, we have less moral dilemna in doing testing on rats than on our fellow human beings. In other words, we are willing to cage them, perform experiments that cause irritation, great discomfort or death to a rat that we feel compelled not to when testing ideas with humans. We generally feel that it is immoral to give a human a condition and then to experiment with it. However, we generally don't feel that it is so immoral to give a rat a condition and then to subsequently try to experiment with it.
The rat in this last context is a model of a human. what surprises most people is how good a model a rat has been to us. In other words, we are a lot like a rat.

It is very helpful to study the rat's external and internal structure because the external and internal structures of a rat are very related to humans and can help you understand your own structure. So, by studying the rat's structure, we can learn more about ourselves.

Differentiate between external validity from internal validity?
External validity is the extent that results from a study generalize to other people, places, and situations--how well the findings stand outside the study and the extent to which they can be replicated. The internal validity is that extent to which the study's design enables it to measure and study what it intends to study.

Can a study have internal validity but not external validity?
Yes. Internal validity is whether or not the experiment is studying what it intends to. External validity is whether or not the study can be generalised outside of the study. For example, if you had a perfect experiment set up, that measures something perfectly, then it will have internal validity. You haven't, however, shown that you would get the same results in different cultures, or in different time periods. Thus the experiment may not have external validity.
