Disease is a structural or functional change in the body that is harmful to the organism. The cause of disease is injury, either internal or external. The disease causing agents that act from outside the body are known as exogenous , while those which act within the body are known as endogenous.
Exogenous causes are further divided into physical, chemical and microbiologic causes. Physical causes are heat, cold, electricity, atmospheric changes and radiations. Chemical causes are poisoning, and drug reactions. Microbiologic causes of the disease are bacteria, virus, fungi and various other microbes.
Hence, the options A, B and D are incorrect.
Endogenous causes are divided into three broad categories, which are as follows:
1. Vascular diseases: These are caused by obstruction of blood supply to an organ or tissue, hemorrhage or altered blood flow.
2. Immunologic disease: These are caused by failure of immune system, its overreaction and abnormal reaction.
3. Metabolic diseases: These include biochemical disorders that may be genetically identified or secondary effects, according to the diseases. They commonly include abnormalities in lipids, carbohydrates, proteins, minerals, vitamins and fluids.
Hence, the correct answer is option
.
