All terrestrial reptiles can be divided into 4 views: turtles, Rhynchocephalia, scaly and crocodiles. In spite of the fact that some of them are predators, others - herbivorous, the device of digestive system at all representatives of a class similar.
Device of a system of digestion of reptiles
The structure of bodies of processing of food is influenced by features of a way of life of animals, their food, the habitat. Digestive system at reptiles has strong likeness with representatives of a class of Amphibia, the small difference consists only in the mouth device. The teeth allowing to hold strong production to crocodiles to lizards differ in the gomodontny system of teeth that means that all of them have the identical form, unlike geterodontny mammals.
Pays attention otgranicheny drinks from a mouth and the structure of language of reptiles. All reptiles it mobile, and on the end have a bifurcation. A gullet at reptiles long that is connected with their big neck. This body is delimited from the throat and a stomach having strong brawny walls. Intestines are developed very well, in it channels of a liver and duodenum open. Depending on the body temperature of these animals (and it is influenced by the environment) duration of digestive process can be from several hours to several days.
Features of work of digestive system
Modern reptiles are generally eaten small land animals. Reptiles with specialized food are a little that is connected with the provision of this class in a biocenosis. In some cases land lizards, snakes and also water turtles use in food quality of a plant. Many reptiles take food jaws – it is promoted by numerous sharp teeth. At snakes, except same, poisonous teeth are well developed. Crocodiles can tear off small pieces from food. The majority of reptiles entirely swallow of the production. Secretion of salivary glands facilitates swallowing. The optimum of action of digestive processes at snakes and lizards occurs only at a sufficient temperature. It is a little higher, than at the Amphibia substantially depending on the environment. Delay of digestive processes can cause poisoning and death of an animal. Therefore reptiles are very well adapted for starvation. Work of intestines is also connected with features of a way of life of such animals. It contains the rudimentary blind gut better developed at herbivorous types. It says about adaptation of digestion of reptiles to food type. Channels of a liver, pancreas help to digest food better. Intestines come to an end with a foul place. Some reptiles are capable to maintain without food up to two years, it demonstrates their ability to adapt to the existence environment.
