Digestive systems
Digestive tracts and their parts & functions
| Question | Answer |
|---|---|
| Where food is taken in and chewed | Mouth |
| Tube that transports food from mouth to stomach | Esophogus |
| First compartment in a ruminant stomach | Rumen |
| Where bacteria ferments food | Rumen |
| Ruminant stomach compartment where food goods before rumination | Reticulum |
| Re-chewing food | Rumination |
| Ruminant stomach compartment also known as the "Honeycomb" | Reticulum |
| Examples of ruminants | Goats, sheep, cattle |
| Examples of monogastrics | Humans, dogs, pigs, cats |
| Organisms that aid in digestion | Enzymes |
| Peristalsis | Muscle contractions that help move food down the esophogus |
| What happens in the mouth | Teeth break down food mechanically, saliva is added |
| Purpose of saliva | Moistens and lubricates food |
| Enzymes | Organisms that help break down food |
| Cardia | Located in monogastric (nonruminant) digestive systems. Prevents food from moving back |
| Compartment in monogastrics that mixes food with hydrochloric acid to break it down | Stomach |
| Compartment in ruminants that contains hydrochloric acid & is known as the "true stomach" | Abomasum |
| List the four compartments of the ruminant stomach in order | Rumen, reticulum, omasum, abomasum |
| Part of the digestive system where nutrients are absorbed | Small intestine |
| Part of the monogastric digestive system where water is absorbed | Large intestine |
| 2 places in the ruminant digestive system where water is absorbed | Omasum, large intestine |
| Where bile is produced | Liver |
| Where extra bile is stored | Gall Bladder |
| The process of how fast or slow your body breaks down food | Metabolism |
| Filters out toxins in the bloodstream (like alcohol in humans) | Liver |
| Where insulin ad enzymes are produced | Pancreas |
| Fluid produced by the liver that aids in digestion | Bile |
| Part of the ruminant digestive system that helps to further break down food after it leaves the stomach | Cecum |
| Where birds store food to be digested later | Crop |
| Part of the poultry digestive system where food is mechanically broken down | Gizzard |
| The part of the poultry digestive system that secretes acid to break down food | Proventriculus |
| Helps to break down fiber in birds (although is not very important) | Ceca |
| Junction in birds where digestive, reproductive, and urinary tracts all meet | Cloaca |
| Point in birds where urine and feces are eliminated | Vent |
| "Holding spot" for manure in ruminants and monogastrics before it leaves the body | Rectum |
| The "exit" point for manure | Anus |
