Human Digestion Versus Bovine Digestion Human digestion and bovine digestion are very different, despite that both species are mammals. The digestive system of a cow is actually more complex than the digestive system of a human. This is due to the fact that cows are ruminants – meaning that they have one stomach with four compartments. The human digestive system is over 30 feet long and is one continuous tube which goes through the various digestive organs in the body and breaks down the food humans consume. It begins in the mouth, where food is taken into the body and chewed to break it into smaller pieces, then amylase – a digestive enzyme produced in the body – is added to it through human saliva. Amylase is a carbohydralase and breaks down the carbohydrates within a food. This allows the body to take some of the nutrients from the food straight away. Once the food is swallowed it enters the pharynx before it is transported to the oesophagus, the pharynx converts the food into bolus. Bolus is chewed food which had been broken down with various enzymes produced in the mouth, it is much easier to digest than food which has just been chewed. The bolus passes into the oesophagus, the oesophagus is directly linked to the stomach and the bolus passes straight through the oesophagus and into the stomach. This is where the bolus mixes with the natural acid inside the human stomach and more enzymes break down the proteins in the bolus until it becomes a semi-liquid called chyme. There is also a thick mucus layer between the stomach lining and the acid it produces, so that the stomach lining isn't compromised by the acid it uses to break down the food. This entire process can take up to six hours. The chyme is carried into the small intestine, where a number of organs begin to work. The pancreas produces a mixture of enzymes to break down fats, carbohydrates and
