    Cows have four stomachs, so what are the functions of these stomachs?

    The stomach of a cow is made up of 4 gastric chambers, namely the rumen, the hive, the double flap, and the wrinkled stomach. Food flows through these four stomach chambers in sequence, and some of them return to the mouth before entering the double-flap stomach before being chewed, a process called rumination.

    These four gastric chambers are not connected in a straight line, but are intertwined. We know that in the food chain.

    among the herbivores.

    is the most important, but it is not easy to feed on plants. Because plants are difficult to decompose compared to meat, they need to be ground with molars. However, molars wear out on their own during the grinding process, so that in many older herbivores, the height of the teeth decreases.

    The Soma people rely on the teeth of the horses to determine their age. The four stomachs of cattle can perform different functions, the rumen, reticulum and valve stomach of cattle are not real stomachs, but are formed by esophageal specialization, and the real stomach of cattle is the last wrinkled stomach, only the wrinkled stomach contains gastric acid.

    The remaining three stomachs have very low levels of gastric acid and are almost neutral, making them ideal for microbial growth that can decompose plants and turn hard-to-digest plants into easily absorbed lipids.

    molecules, therefore, although cattle feed on plants, they can also have a body of muscle. In addition, the four stomachs of the cow can prolong the time that the plant stays in the body, and the longer the plant stays in the body, the more nutrients the cow can absorb.

    1.Rumen Adult cows have a rumen volume of up to 151 litres and can hold 136 kg of contents. The functions of the rumen are:

    1) Temporary storage of feed Cattle store a large amount of feed in the rumen when feeding, regurgitate large feed particles into the mouth when resting, chew slowly, and chew the feed quickly through the rumen to provide space for eating feed again. (2) Microbial fermentation feed continues to enter and flow out of the rumen, and saliva also enters the rumen stably to regulate pH.

    Microorganisms, bacteria, fungi and protozoa are fermented differently depending on the type of feed, and the end product of fermentation is absorbed and utilized by cattle through the rumen wall. Cattle flatulence.

    It is caused by the rumen.

    2.Reticulated stomach: The reticulated stomach is located in the front part of the rumen, and in fact the two stomachs are not completely separated, so the feed pellets can move freely between the two.

    The reticulogastric endothelium has a honeycomb-like tissue, so it is commonly known as the honeycomb stomach. The main function of the net stomach is to act like a sieve, and the heavy objects that are ingested with the feed, such as nails and wires, are present in it.

    3.Double Stomach: The double stomach is the third stomach with tissue-like folds arranged on its inner surface. The effect of the double valve on the stomach is not well understood, and it is generally believed that its main function is to absorb water in the feed and squeeze and grind the feed.

    4.Wrinkled stomach: The wrinkled stomach of a cow is also known as a true stomach.

    Its function is the same as that of the stomach of a monogastric animal, secreting digestive juices and making chyme wet. The digestive juices of the true stomach contain enzymes that digest some proteins, and basically do not digest fats, fibers, or starches. The feed leaves the true stomach in a watery form and then reaches the small intestine for further digestion.

    The undigested material is excreted from the body through the large intestine.

    These four stomachs are rumen, reticulum, double flap stomach, and wrinkled stomach. Rumen: digests most of the feed; Net stomach:

    Strain out the weight (stones, etc.) that the cow has eaten; Double stomach: The rough part of the food is continued to be ground and the thin part is sent to the wrinkled stomach to absorb water and acid. Wrinkled stomach:

    Secretes digestive juices and digestive enzymes, absorbs part of the protein, digests undigested feed and rumen microorganisms in the rumen.

    1. The rumen rumen is anti-plagiar.

    The first stomach is also a unique depleting organ of ruminants, and the rumen is du

    It is a natural fermenter with the strongest known ability to degrade fibrous substances to date. The rumen epithelium can effectively absorb Na+, K+, Cl- plasma, and the absorption of volatile fatty acids can reach 75%, and the absorption rate is butyric acid, propionic acid, acetic acid, which plays an important role in regulating the rumen environment.

    2. The reticulum is located in the front of the rumen, in fact, the two stomachs are not completely separated, so the feed pellets can move freely between the two. The main function of the net stomach is like a sieve, and the net stomach plays a role in filtering as the heavy objects eaten into the feed, such as nails and wires, are present in it.

    3. The third stomach of the valve stomach ruminant. It is located on the right side of the anterior part of the abdominal cavity. The mucosal surface forms many lobes of varying sizes, and there are no digestive glands.

    Its main function is to retain the rough parts of the food, continue to grind them, and transport the thinner parts into the stomach while absorbing a lot of water and acid.

    4. The wrinkled stomach is usually called the true stomach, which functions like the stomach of a monogastric animal, and is different from the forestomach in that the stomach is attached to a digestive gland that can secrete digestive enzymes and has a real sense of digestion, so it is called the true stomach, and it is also called the "glandular stomach".

    1. Rumen.

    The rumen is an important digestive organ of cattle. When cattle are feeding and ruminating, the weakly alkaline saliva secreted by them flows into the rumen, which neutralizes the fatty acids produced during the fermentation of carbohydrates.

    At the same time, the epithelial tissue of the rumen can also absorb Na+, K+ plasma, absorb most of the volatile fatty acids, and play a good role in regulating the internal environment of the rumen.

    2. Net stomach. The reticulated stomach is located in the anterior part of the rumen and is also called the honeycomb stomach because of the honeycomb tissue in the endothelium. The net stomach mainly plays the role of filtration, that is, like a sieve, it screens what the cow eats. For example, there may be some indigestible weights in the feed, such as:

    Nails, stones, etc., are sifted through the stomach of the net, and these things are stored in it.

    3. Valve stomach. The valve stomach is also called the double valve stomach, which is connected to the net stomach in front and the wrinkled stomach in the back. Its main function is to process and grind the rough parts of the food, and to transport the thinner parts to the stomach, while also absorbing a large amount of water and acid.

    4. Wrinkle the stomach. Its function is the same as that of the stomach of a monogastric animal, with digestive glands, which can secrete digestive enzymes, and is the real digestive organ of the four stomachs of cattle, so it is also called the true stomach.

    Summary. Dear, glad to answer for you: Dear According to your description, here is the answer for you.

    Pro, cattle have a total of four stomachs, namely rumen, net stomach, valve stomach, and wrinkled stomach. Rumen: It is responsible for stirring and kneading the food in the stomach to make it easier to digest.

    Net stomach: It is responsible for intercepting heavy objects mixed with food. Flap stomach:

    Responsible for further grinding food. Stomach wrinkle: responsible for secreting gastric acid and digestive enzymes to digest food.

    Cows have several stomachs, all of which have a role.

    Dear, glad to answer for you: Dear According to your description, here is the answer for you. Pro, cattle have a total of four stomachs, namely rumen, net stomach, valve stomach, and wrinkled stomach.

    Rumen: Responsible for stirring and kneading the food in the stomach, making it more limb and easy to dissipate. Net stomach:

    Responsible for intercepting heavy objects mixed with food. Valve stomach: responsible for the entry of the food containing a step grinding.

    Stomach wrinkle: responsible for secreting gastric acid and digestive enzymes to digest food.

    1. What is the function of how many stomachs does a cow have1. The number of cow stomachs There are a total of 4 stomachs in cattle, which are rumen, net stomach, valve stomach, and wrinkled stomach. 2. Function (1) Tummy stomach: The stomach wall muscles of the rumen are strong and powerful, and the food in the stomach is stirred and kneaded through continuous contraction and relaxation, making it easier to digest; In addition, 70-80 of the digestible dry matter and more than 50 of the crude cellulose in the feed are digested in the rumen, and eventually volatile fatty acids, carbon dioxide and hydrogen are produced, which are used to synthesize proteins, B vitamins and vitamin K.

    The rumen epithelium can also effectively absorb sodium , potassium, chloride and other ions. (2) Net stomach: The net stomach communicates with the rumen, and is mainly responsible for filtering out the heavy objects (such as nails and wires) accidentally eaten in the process of eating into Hui.

    3) Flap stomach: The main function is to continue grinding the rough part of the food passed by the net stomach, and then transport the thinner part to the wrinkled stomach, while absorbing a lot of water and acid. 4. Wrinkle the stomach.

    This stomach is the real stomach of cattle, which can secrete gastric acid and digestive enzymes to digest protein and fat from food. It should be noted that after the microorganisms parasitic in the rumen and reticulum enter the rumen stomach, they will also be digested into protein by the stomach to provide nutrients for the growth of cattle.

    The four stomachs of cattle are called rumen, reticulum, valve, and wrinkled.

    1. Rumen.

    The rumen is the first stomach of the four stomachs of cattle, also known as "grass belly", which has a very strong ability to degrade fibrous matter, most of which is located on the left side of the abdominal cavity, occupying almost the entire left abdominal cavity, and a small part is located on the right side of the abdominal cavity. As a unique digestive organ of cattle and other ruminants, the rumen plays an important role in the digestion process, and only by fully understanding its characteristics and functions can cattle be raised.

    2. Net stomach.

    The reticulum is also known as the "honeycomb stomach" or "money belly", which is located in the front part of the rumen, in fact, the rumen and the reticulum are not completely separated, so the feed (especially pellet feed or other harder feed) can move freely between the two. There is honeycomb tissue on the stomach of the net, which functions like a sieve, and the heavy objects that the cow eats, such as stones, nails, wires, etc., are stored in it.

    3. Valve stomach.

    The valve stomach, also known as the "double valve stomach" or "louver", is the third stomach of the cow, located on the right side of the front of the abdominal cavity, with the front through the net stomach and the back of the wrinkled stomach, which has the effect of connecting the upper and lower levels. The mucosal surface of the stomach valve forms many lobes of different sizes, and its main function is to retain the rough part of the food to continue to grind it, and transport the thinner part to the stomach while absorbing a large amount of water and acid.

    4. Wrinkle the stomach.

    Often referred to as the "true stomach", the wrinkled stomach is the fourth stomach of cattle and the only stomach with digestive glands that secrete digestive enzymes for digestion in the true sense of the word. The stomach can digest and absorb some protein, but basically does not digest and absorb fat, fiber and starch.
