Monogastric Digestive System 1 Different Digestive Systems • The three different types of digestive systems are: • Monogastric • Modified Monogastric • Ruminant 2 Digestion is the process by which large, complex nutrient molecules are broken down into simpler molecules capable of being used by the organism for food. 3 Humans, swine, rabbits, chickens and horses all have a simple stomach, which is also known as a monogastric digestive system. 10/10/2024 4 Monogastric • Carnivores and omnivores have monogastric digestive systems. • Monogastric systems have a simple stomach structure and only one compartment. • Some animals with monogastric digestive systems are pigs and rabbits. Humans also have monogastric digestive systems. 5 6 Parts and functions of the monogastric mammal digestive system continued… •Small Intestine -enzymatic digestion and absorption -Functions of the small intestine: digestion of proteins, carbohydrates, and fats; absorption of the end products of digestion 1. duodenum - most digestion occurs here 2. jejunum - some digestion and some absorption occur 3. ileum - mostly absorption -Bile - made in liver, stored in gall bladder, active in the small intestine, emulsifies fat to aid in digestion 7 Parts and functions of the monogastric mammal digestive system continued… •Enzymes in the small intestine 8 Parts and functions of the monogastric mammal digestive system continued… •Cecum - essentially non-functioning in many monogastrics. Rabbits and horses have an enlarged cecum that acts like a rumen and is involved with microbial digestion (fermentation) • Large Intestine -bacterial activity -water absorption -waste storage 9 What type of digestive system is this?
