The human body is made up of cells which form tissues that in turn form organs and organ systems that carry out the physiological functions of the body. Each organ system has specific organs as its parts. The digestive system is made up of the stomach and the intestines and helps in the digestion of food. The musculoskeletal system of the body is made up of bones and muscles that hold the body parts together and helps the body to move.
When there is a disease, there is a malfunctioning of these organs which are indicated by some symptoms. These symptoms makes us to understand that something is wrong with our body. At some point or the other in our lifetime, we suffer from fever, body aches, cold, vomiting and various other diseases which affect the health. These diseases are caused by a wide range of causes such as disease-causing organisms, malfunctioning of the vital organs, nutrient deficiency and so on.
Thus the term disease can be defined in a number of ways.
- Any abnormality or disturbance caused in our body is known as disease.
- The condition in which health is impaired, leading to the departure from the state of health is known as disease.
Disease is the opposite of health as it is the malfunctioning of the body organs due to one reason or the other. The term disease means 'without ease'. In other words, it means being uncomfortable.
