The description of the digestive system’s various organs and functions is shown as below ::
The digestive system is a sophisticated network of organs and mechanisms that collaborate to digest food and assimilate nutrients. The digestive system, which comprises the esophagus, stomach, small and large intestines, liver, pancreas, and gallbladder, runs from the mouth to the anus.
The gastrointestinal tract (GI) and the auxiliary digestive organs make up the two primary components of the digestive system. The mouth, pharynx, esophagus, stomach, small intestine, and large intestine make up the GI tract. The liver, pancreas, and gallbladder are some examples of auxiliary organs.
Pharynx and the mouth including mechanical and chemical digestion start the digestive process in the mouth. Food is broken down into tiny bits by the teeth and tongue, and carbohydrates are first broken down by saliva, which includes enzymes.
The throat and stomach are joined by the esophagus, a muscular tube. To transfer food down to the stomach, it engages in a sequence of contractions known as peristalsis. Known as chyme, the stomach is a muscular sac that combines and grinds food with gastric juice. Additionally, enzymes that start breaking down proteins are secreted by the stomach.
The majority of nutrients from food are absorbed in the small intestine. The duodenum, jejunum, and ileum are the three portions that make up this organ. Additionally, the pancreas and liver deliver digestive fluids to the small intestine .The final undigested substance is absorbed by the large intestine, where it is combined with electrolytes and water to make faeces. The cecum, colon, rectum, and anus are all parts of the large intestine.
Liver Bile, which is made by the liver, aids in the digestion of fats and the absorption of vitamins that are fat-soluble. Additionally, the liver is involved in metabolism and detoxification. Digestive enzymes and hormones that control blood sugar levels are secreted by the pancreas. In the small intestine, the enzymes aid in the breakdown of carbohydrates, proteins, and lipids. When bile is required for digestion, the gallbladder stores it and then releases it into the small intestine.
In short we can conclude that the digestive system is a sophisticated network of organs and mechanisms that collaborate to digest food and assimilate nutrients. We may better grasp the significance of a healthy digestive system for general health and wellness by learning the structure and functions of each organ.
