Digestive System. The digestive stystem consists of 8 parts. When you eat food, it goes straight into your mouth. There the teeth chomp it up and mix it with syliva. It is then swallowed down the oesophagus, which connects the mouth and stomach. Once it reaches the stomach, it is mixed with enzymes which digest the proteins The digestive system. This lesson looks at how our bodies are equipped to digest the food that we eat and why it is necessary. We are going to take a journey through the digestive system, looking at the role of each of the different organs Start studying KS3 Digestive System.

The role of bacteria in digestionFriendly bacteria in the digestive system occur mainly in the colon, also called the large intestine, and in the part of the small intestine furthest away from the stomach.The oesophagus, stomach and first section of the small intestine are mostly bacteria-free because of the deterrent effect of the strong stomach acid and the high level of digestive enzymes. There are over 1,000 types of bacteria in your digestive system with hundreds of strains, but the most common ones are from two families: Bacteriodetes and Firmicutes. Probiotics. Probiotics balance your good and bad gut bacteria to keep your body working the way it should. They help us in many ways Start studying Bacteria and Enzymes in digestion. Learn vocabulary, terms, and more with flashcards, games, and other study tools The digestive system consists of the gastrointestinal tract, which includes the oral cavity, pharynx, esophagus, stomach, and intestines, and a number of associated structures and glands such as the teeth, salivary glands, liver, and pancreas. The bacteria produce a powerful toxin (the shigalike toxin) that causes lesions and inflammation. Although viruses play a role, bacteria are common offenders, with Salmonella and Campylobacter topping the poisoning charts. Some bacteria wreak havoc by multiplying in the body before delivering their toxins, which spark an immune reaction in the gut. Others, such as Staphylococcus aureus, poison us by contaminating food with toxins

Some bacteria eat the fiber during a process called fermentation and release gases such as carbon dioxide and hydrogen as byproducts. According to the Food and Agriculture Organization of the United Nations, over half of the fiber you eat gets completely digested by colonic bacteria and the rest leaves the body as waste By losing weight, you are easing pressure and allowing your digestive system to carry on properly. 10.

The small intestine is the part of the section of the digestive system in the gastrointestinal tract of human beings, also called the small bowel. It includes the duodenum, jejunum, and the ileum, and its primary function is to absorb the minerals and nutrients from the food that we eat. The small intestine on average is about 16 to 20 feet in adults (if it were to be stretched out) but it is. The digestive system of the human body is the sum of the gastrointestinal tract (GIT; also called alimentary canal) and accessory organs (tongue, liver, pancreas, etc.). These two parts together help in the digestion process. The alimentary canal is the long tube through which the food that we eat is passed The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. Inside this tube is a thin, soft membrane lining of epithelial tissue called the mucosa.In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food The large bowel or colon is that part of the gastrointestinal tract which comes between the small intestine and the anal opening. In other words, it starts from the terminal point of small intestine and ends at the anus. The colon is much wider than the small bowel. And, it is this characteristic which gives it the name of large bowel
