Experimental biology refers to a range of approaches in biology that focus on conducting experiments to examine and understand biological phenomena. The word stands in contrast to theoretical biology, which deals with mathematical modelling and abstractions of biological processes. Biology is essentially an experimental discipline due to the complexity of the systems studied. However, as computing power has increased in recent years, it is becoming easier to find approximate answers and validate mathematical models of complex biological organisms.
The physiology of disease is frequently complicated, involving interactions between several organs and tissue types. As a result, many disorders cannot be properly examined utilising in vitro experiments.
