The intestinal flora contains useful but also potentially harmful bacteria. What about mineral ions and vitamins. The action of these waves moves the food forward. Carbohydrate digestion begins with the action of salivary amylase ptyalin in the mouth and continues in the duodenum through the action of pancreatic juice.
Which of them is the only one that does not contain digestive enzymes. The pharynx, or better known as the throat, is common passage for food and air to travel. Mucin is secreted which helps in lubricating the faeces and facilitates their passage.
The enzyme Erepsin present in this ferment helps in the digestion of protein foods. The enzymes which digest protein foods in pancreatic juice is Trypsin. Renin, Pepsin and gastric lipase.
It consists of a mixture of segmentation movements and mass peristalsis which transfers the faecal material into the colon. Triglycerides emulsified by bile within micelles are subject to the action of lipases, which break them down into fatty acids and glycerol.
In that way, chylomicrons reach the liver, where their lipid content is processed and released into the blood in the form of protein-containing complexes called lipoproteins, such as HDL, VLDL and LDL. In mandibulate vertebrates, mandibles and chewing muscles exist to triturate food prior to chemical digestion.
From the liver, nutrients are gathered by the hepatic veins, which discharge their blood content into the inferior vena cava. The jejunum and ileum contain folds that also have the function of increasing the absorption surface. All these movements can be grouped under two headings: In the liver, ingested toxic substances, such as alcohol and drugs, are also inactivated.
It is relatively thinner than jejunum. This feature allows bile salts to enclose fats inside water-soluble micelles in a process called emulsification.
- Comparing the efficiency of digestive system. A digestive system is the food is passed through the body separating the good part for usage and the indigestible part for waste.
There are three types of digestive system, monogastric (carnivore and omnivores), hind gut fermenter and a ruminant. Monogastric includes animals such as pigs, dog.
