食草动物和食肉动物消化系统之间的差异

Key Difference – Herbivoresvs Carnivores Digestive System

动物的消化系统涉及摄取food into forms which could be easily absorbed into the body. This provides essential components for the functioning and the survival of living organisms. The digestive system differs according to the species of organisms. This depends on the type of species, the type of ingestion, their metabolic conditions and the level of energy they need for their survival. According to the type of food that animals consume, living organisms could be categorized into three types such asherbivorous,食肉和杂食。杂食性动物依赖于动植物物质。食草动物仅取决于植物的物质，而食肉动物仅取决于动物物质。草食动物具有特殊的消化系统，因为它们仅依赖植物质。与草食动物相比，食肉动物具有更短的消化系统。食草动物消化系统拥有很长的small intestinewhile the carnivores possess a short, small intestine.这是关键区别between Herbivores and Carnivores Digestive System.

What is Herbivores Digestive System?

草食动物具有特殊的消化系统，因为它们仅依赖植物质。植物满足了食草动物生存所需的能量需求，营养和其他必要化合物。植物材料包含纤维素。因此，需要一种特殊类型的消化机制，因为纤维素仅由酶cellulase。The teeth of herbivorous animals are flat since they need to grind plant material in the buccal cavity to complete机械消化。草食动物的典型消化系统由单个胃和长肠和大盲肠组成。

食草动物牙齿高度特定于食用植物物物。食草动物的磨牙通常是平坦而宽的，这有助于他们破坏和研磨植物。食草动物在上颌和下颌都不存在，但它们尖锐地撕裂了植物材料。山羊，牛和马等许多草食动物都有可以侧向移动的颌骨。在其大小袋状的盲肠中，含有纤维素酶的数百万个细菌。这有助于消化纤维素。这就是为什么草食动物拥有比食肉动物更长的肠道的确切原因。牛，山羊和绵羊等草食动物具有多种胃。这些被称为ruminant物种,他们有四个胃。这一切ows these animals to swallow partially chewed plant matter mixed with saliva which is known as a bolus. The partially chewed plant matter first enters the first two stomachs that are, the rumen and the reticulum respectively. Here the plant matter is stored until taken for later use.

When the animal is at rest, it can cough up the partially chewed food back into the buccal cavity and chew it completely forming another bolus of food. This bolus enters the third and fourth stomach; omasum and abomasum. In the omasum, the liquid part of the bolus which contains water and minerals are absorbed into the bloodstream. The abomasum is similar to the human stomach where chemical digestion of food takes place, and the digested nutrients are absorbed in the small intestine.

What is Carnivores Digestive System?

与草食动物相比，食肉动物具有更短的消化系统。这是由于食肉动物拥有的饮食可能很容易分解的原因与食草动物中的纤维素成分不同。食肉动物通过杀死其他动物来获得食物。他们还可能杀死其他食肉食品。这是一个重要方面ecosystem这阻止了动物的人口过多。食肉动物通常位于食物链。To fulfill the ingestion of food by carnivores, they possess sharp and strong teeth. Since they have a different diet pattern when compared with herbivores and omnivores, the strong set of teeth that carnivores possess help them to kill their prey and tear flesh from it. This process is assisted by the presence of a unique set of canines and incisors that are sharp and pointed. The canine is present on either side of the incisors, and the carnivore canine is easily identified. Since the most of the physical digestion within the buccal cavity of carnivores are done by the teeth at the front, carnivores possess few molars in both lower and upper jaw.

The presence of a pointed and sharp canine tooth is not an indication of that animal being a carnivore. It only provides information about the diet pattern which contains animal meat. Once the food is ingested and broken down into absorbable forms, it is absorbed in the small intestine. Water and nutrients are mostly absorbed in the large intestine. Also at the large intestine, less than 4% of fat and other minute amounts of proteins are absorbed. Carnivores do not possess cellulose-digesting enzymes to digest cellulose.

What is the Similarity Between Herbivores and Carnivores Digestive System?

• 两者都通过将它们分解成很容易吸收到体内的形式来参与他们摄入的食物材料的消化。

Summary – Herbivoresvs Carnivores Digestive System

The digestive system is an essential component in the survival of living organisms. It provides the body with needed nutrients and other essential components. According to the type of food animals obtain, they could be categorized into three groups as, carnivores, herbivores and omnivores. The digestive system differs according to the species of organisms. This depends on the type of species, the type of ingestion, their metabolic conditions and their level of energy needed for survival. Herbivorous animals have a special type of digestive system since they only depend on plant matter. They have the ability to digest cellulosic compounds since they possess cellulose enzyme. Carnivores obtain their food by killing other animals which include herbivores and omnivores. They possess a shorter digestive system. This is the difference between herbivores and carnivores digestive system.
