Key Difference – Digestion in Humans vs Ruminants
消化系统在动物中,在消化的背景下是一个重要的系统ingestedfood into simpler forms that could be easily absorbed by the body cells. This provides all the essential compounds needed by the body for the existence and development of the living organism. Different digestive systems have evolved according to different species, their feeding patterns, and their栖息地。反刍动物物种仅在植物物质上生存。他们是草食性动物。所以,反刍动物的消化系统随着瘤胃的存在而进化,这是一个复杂的胃,有四个不同的隔间。人类是杂食性的,依靠动植物物质,因此它们的消化系统由一个胃组成。这是关键区别在人类和反刍动物的消化之间。

What is Human Digestion?
人类是omnivorousspecies that depends on both animal and plant matter. Their digestive tract differs from other species. Humans do not containenzyme纤维素酶。所以,they are unable to digest cellulosic matter. The human digestive tract is also referred to as the gastrointestinal tract. It is composed of different accessory glands which include the肝,,,,胆囊,,,,胰腺,,,,salivary glands and the tongue. The human digestive tract is composed of mouth and buccal cavity,esophagus,,,,stomach,,,,小肠,大肠,直肠和肛门。
Mechanical digestion食物发生在颊腔内。唾液被唾液腺分泌,并与食物混合。在舌头的帮助下,机械消化的食物被转化为液化的推注,以方便吞咽。化学消化由于唾液含有唾液淀粉酶,因此食物也从颊腔开始。在胃中,胰腺和辅助腺的不同酶被释放出来,摄入的食物被完全化学消化。
The small intestine is lined is developed with a higher surface area for effective absorption of nutrients. Most of the nutrients are absorbed within the small intestine into the bloodstream. Water is mostly absorbed by the large intestine. The undigested food particles are eliminated from the body through the anus where the particles are temporarily stored in the rectum.
反刍动物的消化是什么?
牛,绵羊和山羊等动物被认为是反刍动物。反刍动物属于该类别,草食动物。它们仅依赖植物物质。食草动物,包括反刍动物,具有较高数量的微生物,这些微生物含有纤维素酶,以消化植物质量中的纤维素化合物。与人类相比,反刍动物具有复杂的消化系统。由于存在瘤胃,它们被称为反刍动物。瘤胃是一个复杂的胃,其中包含四个不同的隔间,包括瘤胃,网状,奥马苏姆和肥胖。所有四个隔室在结构和执行功能上彼此不同。在这四个隔室中,瘤胃是最大的隔室,其中包含具有酶纤维素酶的微生物种群,并进行了不同的发酵反应。
反刍动物的消化系统从口腔和颊腔开始。它拥有32颗牙齿,涉及摄入的植物物质的机械消化成与唾液混合的液化剂量,以便于吞咽。部分咀嚼的推注最初进入瘤胃并经历发酵短的时间内。当动物rest, it has the ability to cough up the partially chewed food back into the buccal cavity and completely chew it to from another bolus of food. This is directed to the rest of the compartments. In the reticulum and abomasum, enzymatic digestion takes place and the nutrients which are digested, are absorbed in the small intestine. In the omasum, water and minerals that are present in the bolus are absorbed into the bloodstream. The abomasum and the small intestine are similar to that of humans. The undigested food bolus then enters the rectum and leaves the body as fecal matter. Herbivore fecal matter appears in green color and contains a higher percentage of water.
What are the Similarities Between Digestion in Humans and Ruminants?
- Both are involved in the digestion of ingested food.
- 两种类型的机械消化发生在颊腔中。
What is the Difference Between Digestion in Humans and Ruminants?
Digestion in Humans vs Digestion in Ruminants |
|
人类的消化是涉及将动植物物质分解为可吸收形式的过程。 | Digestion in ruminants is the process which involves only the digestion of plant matter. |
Stomach | |
人消化系统有一个胃。 | 反刍动物的胃部复杂,有四个不同的隔间。 |
Cellulase | |
人不含纤维素。 | 反刍动物s contain cellulase that digests cellulose. |
Bolus | |
In humans, the bolus is once swallowed it completes the digestion of containing food particles. | In ruminants, when the food bolus is swallowed, it could be coughed up again for further mechanical digestion. |
概括 -Digestion in Humans vs Ruminants
不同的动物具有不同类型的消化系统。不同的消化系统根据不同的物种,其喂养模式及其栖息地进化。反刍动物仅在植物物物上生存。他们是草食动物。因此,它们的消化系统是随着瘤胃的存在而演变的,瘤胃是一个复杂的胃,有四个不同的隔间。人类是杂食性的,依赖于动植物的物质。他们的消化系统由一个胃组成。在这两个系统中,无解的食物材料被消除为粪便。这是人类和反刍动物的消化之间的区别。

Some people have swallowed food returned in their mouth after eating and it’s chewed again. Are they Ruminant or nonruminant? Thank you.
