Comparison between human and ruminant digestive system

Takes a person into his mouth, where they chew, confused with the saliva selected by the glands in the mouth. After chewing, some of the food is collected in the language. They are then ingested and the opening of the larynx is closed by a piece of tissue called epiglottis. This wing prevents food from entering the airway. If some food spills in this medium, the effect of reflux is coughing to discard the food. The food comes from the esophagus to the stomach and the contraction of the stomach musculature ensures the further mixing and mechanical disintegration of the meal, while confusing with the stomach-induced gastric juice.

The stomach has a mucous membrane lining and is protected from gastric juice containing enzymes and hydrochloric acid. The food is broken down into smaller particles so it is easier to absorb into the blood stream and other foods pass through the pylori sphincter valve into the small intestine and duodenum, a muscle ring at the end of the stomach and intestine. In the small intestine, the rhythmic movements of the walls sliced ​​food and mixed with digestive tract, including pancreas and bile juice (epithelium produced by the liver and gallbladder). as a result of the effect of the enzymes present in these juices.

Absorption of digestive nutrients occurs primarily through the small intestinal mucosa. The rhythmic movement of the intestine separates the non-absorbed foods and blood from the blood into the colon, where the water is absorbed by the intestinal walls and the partially dehydrated channels into the rectum from which the body is excreted through the anus as with the faeces. Ruminant is called "chewing the cud", and this name can be given to those mammals who have ovarian and combing gills such as cattle, sheep, goat ruminants.

Other groups of ruminant animals include antelopes, deer, camels, llamas, hippos, larvae and kangaroos.

The ruminant has a stomach consisting of four compartments (the camels must have three.)

The food partially chews, then swallows and enters the first compartment called the rumen. The large stomach has no digestive juices or phlegm glands, and food is attacked by a large number of live protozoans, microbes and bacteria that are already present in the ruminant stomach. The degradation of the cellulose, which is largely carried out at this stage of the stomach, the food is recovered from time to time in small amounts in the mouth and slowly chews the pulp, and when the food is pressed again, a second compartment, a reticulum, enters. This section of the stomach further degrades cellulose and passes it to the third compartment, the omasum. OMASUM:

Omasum contains large, leafy structures that increase the surface for effective water absorption, muscles mix and further reduce until they enter the fourth compartment, called abomasum.


"True Stomach" It's a stomach like ours. In this body, gastric juice is excreted, contains hydrochloric acid that kills most microbes and begins to digest them and absorbs their contents to provide essential vitamins, minerals, and amino acids.

Ruminants have a special metabolism due to the presence of digestive bacteria. The protein needs are provided by ruminal bacteria, which use simple materials in urea and inorganic sulfates to produce proteins. This is a significant difference between ruminants and other animals as they produce their own protein. Protein is a dietary requirement for any other animal.

Most ruminants (cattle, sheep, goats) lack the upper incisors – replacing the tough "prosthesis", which is well developed even with lower incisors. Well-developed molars and premolars for grinding "Lateral". The toothless gap between the teeth and the premolars allows the tongue to manipulate the food. Chewing movements are stimulating, leading to increased salivary glands, especially on the side where the chewing has taken place. Up to 200 liters of cattle can be produced within 24 hours. Saliva has rich bicarbonate to neutralize fatty acids produced by fermentation.



Special language and lip for grasping and tearing.

Well-developed molar and premolar sanding, the movement is "lateral".

Most ruminants have upper teeth replaced with "Dental Pad".

The gap between the premolar and the molar allows the tongue to manipulate the food in small amounts before swallowing.

The mouth is nourished.

Complex digestive system (Four stomachs).

The regurgitation of relaxing chewing, a tooth of teeth of life, teeth worn out with age.

The protein needs of rumen bacteria.

Herbivores – no meat. People:

Movement of upper and lower teeth "Vertical" Intersecting teeth and dog shearing operations are produced that are used for cutting, crushing, pretreatment and molar food.

Two types of tooth – degradation and inadequate nutrition – replace the bone profile (false teeth).

Food is taken to mouth.

Digestive system (a stomach).

Protein is a dietary requirement that is consumed by different foods.

Vomiting is more common with predators and omnivores. A strong rejection of stomach contents from the mouth.

Different foods for the production of various other nutrients.

Health status, weather changes, irritability, and stress can affect digestive processes.

Omnivore – Meat and Plants.


Food, water and oxygen to maintain life requires similar nutrients and produce waste.
