Draw the parts of the digestive system and explain the process of digestion
Answers
Answer:
Explanation:
The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.
Answer:
Digestion is the process by which the complex food is broken down into simpler, soluble chemical compounds which are then used as nutrients by the body. The food is digested physically, by mouth, or chemically, by enzymes. The digestion begins at the mouth. In the mouth, the food is broken down into smaller pieces by teeth. It is then mixed with saliva. Enzyme amylase breaks down starch into simple carbohydrates. The food then travels to the esophagus via the pharynx. By the peristaltic movement, the food moves from the esophagus to the stomach. The acid and enzymes present in the stomach break down the food further. Gastric juices present in the contains protease enzyme which breaks down proteins. Food then enters the small intestine. Enzymes released by the pancreas and bile released from the liver enter in duodenum part of the small intestine. Bile carries out the digestion of fat. Enzymes released by the pancreas break down protein, fat, and carbohydrates. Absorption takes place in the other two parts of the small intestine, namely the jejunum and ileum. The indigestible food enters the large intestine. In the large intestine, maximum absorption of water takes place. The waste then enters the rectum in the form of stool which is coming out from the anus.
