  1. Click the green arrow to begin Animal Digestion

  2. Instructions • Green arrow to go forward • Red arrow to go back • Home Icon to return to beginning of slide show

  3. What is animal digestion? Look at the pictures below: How does this relate to agriculture?

  4. What is Animal Digestion • If you said: breaking down then you are correct • The actual definition is: process of breaking down food into simple substances that can be absorbed by the body • Another part of digestion is absorption: -process of taking the digested parts of food into the bloodstream

  5. What is Animal Digestion? • A. breaking down of food • B. breaking down of liquid • C. breaking down of air

  6. Correct! Great job! • The definition of animal digestion is: process of breaking down food into simple substances that can be absorbed by the body

  7. Incorrect • Good try but please try again • Click the arrow to return to the question and try again

  8. Digestive Systems • The digestive system consists of the parts of the body involved in chewing and digesting food. • Digested food moves through the animal’s body and absorbs the products of digestion

  9. 4 basic types • monogastric (simple) • ruminant (polygastric) • pseudo-ruminant • avian

  10. Monogastric or simple • contains a single-chambered stomach • found in humans, swine, dogs, and cats.

  11. Monogastric • What animals have a monogastric system?

  12. Correct! Great Job! • Pigs, dogs, cats and humans have a monogastric digestive system

  13. Incorrect • Good try but please try again • Click the arrow to return to the question and try again

  14. Ruminant or polygastric • One large stomach divided into four compartments • found in cattle, sheep, and goats. • An animal with this kind of digestive system is called a ruminant

  15. Digestive systems • The rumen is the largest section of the stomach • 60% of the stomach. • Contains bacteria and other microbes that promote fermentation • Food is ingested, eructated (belched up), chewed, and then swallowed again

  16. Digestive systems • The reticulum • Has honeycomb-like ridges • Aids in keeping the food in the rumen mixed with water and saliva • Until it is the right consistency • Once the right consistency is reached, the mixture can pass on into the lower digestive tract

  17. Digestive systems • The omasum is a small compartment • Main sight for water absorption • particles are squeezed and dehydrated, as well as sorted • The compartment acts as a filter for the abomasum

  18. Digestive systems • The abomasum, or “true stomach,” is the site of digestion • Secretes gastric juices consisting of hydrochloric acid and pepsin • The abomasum is similar to the stomach in a monogastric animal

  19. Ruminant Digestive System • What are the four chambers of a ruminant stomach?

  20. Correct! Great Job!! • Rumen, Reticulum, Omasum, and Abomasum

  21. Incorrect! • Good try but please try again • Click the arrow to return to the question and try again

  22. Pseudo Ruminant • A pseudo-ruminant can utilize large amounts of roughages because of its greatly enlarged cecum and large intestine • Examples of pseudo-ruminants are horses, rabbits, guinea pigs, and hamsters.

  23. Pseudo Ruminant • Why can pseudo ruminant’s consume large amounts of forages?

  24. Correct! Great Job! • Pseudo ruminants can consume large amounts of forages because their enlarged cecum.

  25. Incorrect • Good try but please try again • Click the arrow to return to the question and try again

  26. Digestive systems • The avian digestive system • Found in poultry. • Since a bird has no teeth, no chewing is involved • The esophagus empties directly into the crop.

  27. Digestive systems • The crop is where the food is stored and soaked • From the crop, the food makes its way to the gizzard • The gizzard-very muscular organ-which normally contains stones or grit that grinds the food • Digestion in the avian system is very rapid

  28. Avian Digestive • Name two important parts of the avian digestive system where the food is stored and where the food is broken down.

  29. Correct! • The crop stores the food and the gizzard breaks it down.

  30. Incorrect • Good try but please try again • Click the arrow to return to the question and try again
