So the features of disease include etiology, the pathogenesis, the morphological changes, and the clinical signs and symptoms. So etiology. Once again we have the -ology ending on the end, so etiology is the study of why things are. So etiology can be biologic such as bacteria or viruses, they can be physical such as from trauma or burns, they can be chemical from alcohol or poisons, it can be inherited such as some types of heart disease can be inherited from family members, or they can be congenital which simply means that they've been there since birth. So what is pathogenesis? Many diseases are thought to be of a genetic predisposition or from an environmental cause.
