How do digestion work in human being
Answers
Explanation:
Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules
Answer:
In Human digestive system, there are many parts that work together. The food that you eat has biomacromolecules, which are nothing but the carbohydrates (such as sugars), proteins, lipids (such as fats), and nucleic acids. These have to be converted to their simpler forms so that your body can absorb it. These biomacromolecules are the building blocks that you require to maintain your body, which is also made of these large biological molecules, along with water!
This process of converting complex food substances (molecules) into simpler forms to facilitate absorption is called Digestion. In humans, this system consists of many parts and organs, including the alimentary canal, digestive glands, and a few accessory organs such as the teeth, salivary glands, tongue, pancreas, liver, gallbladder etc.
Nevertheless, the starting point where digestion actually starts in the mouth! From the mouth, it passes through the alimentary canal, which is also called the gastrointestinal tract. This tract consists of the pharynx, esophagus, stomach, small intestine, large intestine, and anus. The mouth can be considered as the anterior opening of the alimentary canal, while the anus is the posterior opening.
