Digestive system is an important biological system inside our body. It is the function of the digestive system to digest the food we eat into useful energy and excretory wastes. Without the proper functioning of the digestive system an organism cannot lead a normal lifestyle. A kidney failure may eventually leads to other complications and may become fatal if necessary treatment is not received . We have to look into every organs involved in the digestive process. The primary organ is our mouth itself. The saliva present in the mouth would start the process of digestion from mouth itself. Teeth will help to convert the food into a paste form so that it can be easily digested by other organs: That is why its important to chew the food well. The chewed food will then goes to the stomach via oesophagus . Oesophagus have a wavy unidirectional movement named peristalsis which helps in the movement of food
The food reaches stomach and it gets digested in the Hydrochloric acid secreted in the stomach. Later the food moves to small intestine where the absorption process occurs, the energy is absorbed by the body in this phase.
The food then moves to large intestine and to rectum . The food is now fully converted to energy and the only remaining is now excretory waste. The waste is expelled via anus. The digestive process is regulated by many hormones, liver and kidney.
