What role does histology play in understanding normal physiological processes?
Histology is not only pivotal in diagnosing diseases but also in understanding normal physiological processes. By studying the normal architecture and function of tissues, researchers can better understand how deviations lead to disease. For example, examining the structure of alveoli in the lungs helps in understanding how gas exchange occurs under normal conditions and how it is impaired in diseases like chronic obstructive pulmonary disease (COPD). This understanding aids in identifying what constitutes a pathological state and the causative factors responsible for such changes.
