Sheep
By: Hunter Creech, Lindsey Walker, & Tyler Wichman
Accessory Organs
( Chemical )
- Liver~ Stores carbohydrates, produces bile, and processes nutrient rich incoming blood
- Pancreas~ The gland between the small intestine and stomach. Produces important hormones and secretes a pancreatic juice, containing enzymes for digestion and absorption
Digestion
Mouth & Esophagus
(Mechanical & Chemical)
Cecum
( Chemical )
1. Through mouth
2. Down the esophagus
3. Into the rumen and reticulum
4. The feed moves back up the esophagus where it will be chewed
5. Moves to the omasum
6.Moves to abomasum
7. Goes to the small intestine
8Through the large intestine
9.Goes through the rectum as feces
- Mouth~ Does not have upper incisor teeth. They use their lower teeth, tongue, and lips to tear and chew their food. Salivary glands produce saliva that break down food
- Esophagus~ A long tube of striated muscle that connects from the mouth to the stomach. Bound by physiologic sphincters.
Polygasric
( Chemical & Mechanical )
Sheep Digestive System
- Cecum~ Not important because the digesta having prior exposure in the rumen - reticulum for breakdown
- Rumen~ The first chamber that mixes food and moves it forward to the stomach chambers
- Reticulum~ The second chamber in charge of wast removal and movement
- Omasum~ The third chamber in charge of the absorption
- Abomasum~ The chemical breakdown of food
Rectum & Anus
( Mechanical )
- Rectum~ Stores feces until defecation
- Anus~ End of the system and controls expulsion of feces
Small & Large Intestine
( Mechanical & Chemical )
- Small Intestine~ Plays an important role in the nutrient absorption
- Large Intestine~ Absorbs water from matter and gets rid of feces.
