In human communities, due to many interconnected causes, health and diseases are very complex issues. The ideologies of health and diseases are very complicated. To know that what causes diseases and how we can prevent them, we should first understand what health and disease means.
The role of cell:
The cells are the basic units of living organisms. They are made up of a wide range of chemical substances such as proteins, carbohydrates, fats, lipids, etc.,
As we see in the above pictures, they appear to be static, but in reality, they are dynamic in nature because always something or the other is continuously happening. These cells migrate from place to place. Certain cells do not move from place to place as they are undergoing repair processes. Every second in the body a wide range of new cells being produced.
In the organs or tissues of the body, there is a wide range of specialized activities happening. Some of them are the beating of the heart, the process of breathing in the lungs, the filtering of urine in kidneys and the thinking mechanism of the brain.
All these activities are interconnected with each other. This can be justified because if the kidneys stop filtering urine, it leads to the accumulation of poisonous substances. Due to this, the brain will not be able to think correctly. The body performs all these related activities with the help of energy and raw materials that are obtained from outside the body. Hence, it can be concluded that food is the primary requirement for the proper functioning of cells and tissues. The prevention of appropriate functioning of cells and tissues will lead to a lack of adequate activity of the body.
