THE HUMAN DIGESTATION:
The food is introduced into the mouth where it is chewed, mixed with the saliva that is secreted by the glands in the mouth. After chewing, a portion of food is collected in the tongue. Then, swallows and the larynx opening closes with a small tissue flap called epiglottis. This flap prevents food entering the respiratory tract. If some food is lost in this treatment, there is a cough reflux action to expel the food.
Food passes from the esophagus to the stomach, contractions of the stomach muscle wall ensure a greater mixing and mechanical disintegration of foods, which at the same time mixes with the stomach gastric juice secreted by the stomach.
The stomach has a mucous membrane coating and is protected against gastric juice containing enzymes and hydrochloric acid. The food breaks down into smaller particles to facilitate absorption in the bloodstream and the rest of the food passes into the thin intestine and the duodenum through the pyloric sphincter valve, a muscular ring at the end of the stomach and the intestine.
small intestine, the rhythmic movements of the walls bounce the food and mix it with digestive juices, which include pancreatic and bile juices (bile is produced by the liver and is stored by the bile bladder) , the digestion is produced from the action of the enzymes present in these juices.
The absorption of digestive nutrients occurs mainly through the mucous membrane of the small intestine. The rhythmic movements of the intestine force unimpeded food, and the excreted matter of the blood in the large intestine, where the water is absorbed by the walls of the intestine and the partially dehydrated material passes to the rectum from which it is extracted from the body through the stool.
EL RUMINANTE FOOD SY WE ARE
The name ruminant means "chew the dumb" and is a name given to mammals of even
39; animals such as ruminants include antelopes, deer, camels, flames, hippos, fools and kangaroos.
The ruminant has a stomach made up of four compartments (the camels have three.)
The food is partially chewed and then swollen and passes into the first compartment called the rumen The large stomach does not have digestive juices or excretory glands present and food is attacked by a large number of living protozoa, microbes and bacteria that are already present in the walls of the ruminant stomach. The breakdown of cellulose, which is composed mainly of plants in this section of the stomach, is occasionally regurgitated in the mouth in small amounts and is chewed slowly in the pulp, and when s & # 39 ; it ingests another feeding, enters a second compartment called reticulum.
This section of the stomach breaks the cellulose further and passes it to the third compartment called omasum.
THE OMASUM:  Omasum contains large leafy structures that increase the surface for efficient water absorption, there the muscles rise and still reduce it Even more so that it enters the fourth compartment, called abomasum.
EL ABOMASUM:  "True stomach" A stomach very similar to ours. In this organ, gastric juice is secreted, contains hydrochloric acid that kills most microbes and begins to digest them and their contents are absorbed in providing essential vitamins, minerals and amino acids.
Ruminants have specialized metabolisms due to the presence of digestive bacteria. Protein needs are provided by rumen bacteria that use simple urea and inorganic sulphate substances to make these proteins. This is an important difference between ruminants and other animals because they produce their own protein. Protein is a dietary requirement of all other animals.
In most ruminants (cattle, sheep, goats) there is an absence of upper incisors – replaced by a well-formed "dental chest" incisors lower. The well-developed molars and the premolars for the grinding movement are "sides". The gap without teeth between incisors and premolars allows the language to manipulate food. Chewing movements act as stimuli, leading to a growing salivation, especially on the side where chewing is made. In cattle up to 200 liters it can occur in 24 hours. Saliva is rich in bicarbonate, which serves to neutralize the fatty acids produced by fermentation.
Specialized tongue and lip to catch and tear
Molars well developed and premolars for grinding, the movement is "lateral ".
In the majority of ruminants, the upper teeth replace with "toothbrush".
A gap between premolars and molars allows the language to manipulate food in small quantities before swallowing.

Digestive system (a stomach).
Protein is a dietary requirement and is supplied by the intake of various foods.
Most common vomids in carnivorous and omnivorous. Forcible exception of the gastric contents of the mouth.
Variety of foods to obtain several other nutrients.
Illness, climatic changes, irritability and stress can affect digestive processes.
Omnivores: meat and plants.
Food, water and oxygen to sustain life, we need similar nutrients and we produce waste.
