Question

-Почему у разных животных различная длина кишечник-у собаки в 4-6 раз длиннее её тела, у кролика-в 15 раз, у овцы-в 28 раз? -Что такое<<подпушь>>Какова её роль? ----- -----Почему в жаркую погоду собака высовывает язык?

Answer 1

Все собачьи - плотоядные животные, длинный кишечник им не нужен, овцы - жвачные животные с многокамерым желудком. Поедая в основном растительную пищу, которая должна перевариться и из нее образоваться доступные питательные вещества, необходим длинный кишечник, это характерно для всех травоядных и особенно для многогастричных.

Different Lengths of Intestines in Animals

The length of the intestines can vary among different animals, and it is primarily influenced by their diet and digestive system. The length of the intestines is related to the type of food an animal consumes and how efficiently it can extract nutrients from that food.

Carnivores, such as dogs, have a relatively shorter intestine compared to their body size. This is because their diet consists mainly of meat, which is easier to digest and requires less time for processing. The shorter intestine allows for faster digestion and absorption of nutrients from the meat.

Herbivores, on the other hand, have longer intestines to aid in the digestion of plant material. Plant matter is generally more difficult to break down and requires more time for fermentation and extraction of nutrients. Animals like rabbits, which are herbivores, have a significantly longer intestine compared to their body size to facilitate the digestion of fibrous plant material.

Ruminants, such as sheep, have an even longer intestine due to their unique digestive system. Ruminants have a specialized stomach with multiple compartments, including the rumen, where microbial fermentation takes place. The longer intestine in ruminants allows for the absorption of nutrients from the partially digested plant material that passes through the rumen.

These differences in intestinal length among animals are adaptations that help them efficiently extract nutrients from their respective diets. The length of the intestine is a result of evolutionary processes and the specific dietary requirements of each species.
