Animal Digestion

Vent

Where the wastes leaves the avian's system.

Peristalsis

Wave like movements to push food through digestion system

Pancreas

Organ that creates and secretes enzymes for fats, starch and protein

Duodenum

Beginning of small intestine where digestive enzymes are added from the gall bladder and pancreas

Rumen

The largest compartment of the ruminant digestive tract. It ferments hay.

Reticulum

The compartment of the ruminant stomach. Catches foreign material. Honey Comb texture

Omasum

The third compartment of the ruminant stomach. It acts as a filter. Looks like pages of a book!

Stomach

A muscular organ secretes acids and squeezes foods.

The three parts to the small intestine

Duodenum, jejunum, ilium

Crop

Food storage in birds prior to stomach. where food is stored and soaked.

Bile

Produced in the liver, digests fatty acids and fats.

Chyme

Partially digested food

Gall bladder

Stores and releases bile from the liver

Diffusion

Movement of molecules from high to low concentration - how nutrients are absorbed into body

Saliva

Softens food contains amylase to digest starches

2 Organs with bacterial digestion of roughages or hay

Cecum and Rumen

Coprophagy

Eating feces to gain nutrients

Ruminant

The digestive system where an animal can easily digest roughages most have four chambers to their stomach

Monogastric

A digestive system that contains one stomach.

Avian

Chicken or Bird

Rumination

Chewing Cud - regurgitated food from the rumen

Abomasum

The "true stomach" of the ruminant digestive system. It secretes gastric juices consisting of hydrochloric acid.

Esophagus

A tube that connects the mouth to stomach

Large Intestine

The last part of the digestive system. The site where water is absorbed and the nutrients enter the bloodstream.

Cecum

Organ between small and large intestine. Digests hay. Horses/rabbits have large ones.

Rectum

The final section of the large intestine that ends at the anus.

Proventriculous

The stomach of a chicken.

Gizzard

Organ that Acts as the teeth for the avian digestive system and grinds up food with gravel

Ceca

Organ in hind gut digesters Located between the small and large intestine used for digestion of fiber with the help of Bacteria.

Cloaca

Where the digestive system and urinary system meet. .

Enzyme

Chemical that speeds up the digestion process.

Viili

small finger-like projections on intestine wall for nutrient absorption

How many times ruminants chew cud/ day

6-8 times

Cud

Regurgitated food in ruminants

Canines

Teeth meant to eat meat in carnivores

Incisors

Front teeth meant for clipping plants

Lipase

enzyme that breaks down fat

Amylase

enzyme that breaks down carbohydrates

Lactase

Enzyme that breaks down milk sugar lactose

Hindgut digestion

-Horses, guinea pigs, rabbits
Large cecum and colon allow fermentative digestion in hindgut similar to rumen
