Nutri1: Animal digestive systems. There are three different types of digestive tract: monogastics, the most suitable type of digestive tract for carnivores and omnivores; Ruminant, used for herbivores, containing four stomach chambers instead of the singular used for monogastics and hindgut fermenters; lastly hindgut fermenters, a tract used for a majority of herbivores with the exception of large avian species which has an extremely long large intestine. Although there are three tracts in total I will only be analysing two, these two being monogastric and ruminant. For both tracts I will explain the systems and individual parts of each, using an example for both, for monogastics a cat and for ruminants a cow. Preceding these explanations, I will then assess and compare the two tracts and explain how efficient they are and also explain how foodstuffs are broken down into smaller pieces and absorbed by the digestive system for use by the animal for use. Monogastric Tract The monogastric tract, as stated earlier, is mostly seen in carnivores and herbivores. It features a mouth, a pharynx, an oesophagus, a single chambered stomach, a liver, a spleen, a pancreas, a gall bladder, a caecum, a small intestine (Duodenum, jejunum, ileum,) and a large intestine (the colon, rectum and anus.) Avian monogastric species will additionally have a crop to help with their digestion; substituting for teeth the crop uses swallowed stones to grind up food stuffs. To explain the process of
