There are a few reasons why scientists dissect rats. One reason is to learn about their anatomy. By looking at the rat’s internal organs scientists can learn how the different parts of the rat’s body work together. Another reason why rats are dissected is to study diseases. By dissecting a rat that has a certain disease scientists can learn more about how that disease works and how to treat it. Finally rats are also dissected to test new medical treatments. By testing new treatments on rats scientists can see if they are safe and effective before testing them on humans.
