Many creatures have only one stomach, so why can a cow have four?

To know why cows have so many bellies, we must first know what the four stomachs of cows are.

We know that in the food chain, the ecological location of the herbivore is the most important, but it is not easy for it to eat plants as food. Because it is difficult for plants to decompose relative to meat, it is necessary to grind with moles. However, teeth grinding also loses the grinding process, so there are years of eating animals, and the height of the teeth decreases.

Thais use the teeth of horses to determine their age.

Why do cows have 4 stomachs but only 1 stomach?

In addition, it is difficult to digest, and for most animals, the stomach has difficulty absorbing nutrients from plants, resulting in a very limited number of nutrients that can be obtained from plants. For example: the giant panda, although the bamboo eats the giant panda, its stomach is not suitable for the bamboo that digests fiber, so they can get limited energy, so they spend more than 10 hours a day eating more than 10 hours.

When not eating, the giant panda will also choose to sleep to reduce energy consumption.

In response to this strategy, the ruminant representatives of cattle have developed an anti-Japanese skill: ruminants. Okay, it's for reckless food to eat, continue to grind, and then get into the stomach, the benefits of doing so:

It can be eaten quickly, and the food after eating will be stored in the stomach and then wait until the food is safe and then the food in the rumen will be dried into the mouth.

If there is no such stomach, there may be a cow to represent the ruminant, nor is it now in the ecological location of desalination.

Why only one stomach?

In fact, it is not only the stomach, the lion, the tiger and the most primates, but most of the intestines of most primates allow the food to remain in the body for a long time, so that the same in the food can be fully absorbed.

But humans are the exception, humans only have stomachs and intestines that other primates lack. The reason is because for a long time, human beings have used fire, using fire to cook food can greatly save human digestible food, so human beings can get nutrients in food without longer digestion time.

Therefore, even though humans have stomachs, they can still absorb enough food nutrients.

Summary. Animal food has a lot to do with its own physical structure, humans belong to eating animals, so the human digestive system is between grazing animals and carnivores. Cattle are herbivores, and many stomachs help them store food, break down food, and digest food.

They are using this skill, which is half of the herb.

Cattle have four stomachs, namely wrinkled stomach, rumen, net stomach, valve stomach, wrinkled stomach is usually called true stomach, this stomach has digestive enzymes secreted by digestive glands, can digest the food eaten by cattle, so it is also called true stomach, rumen can fully degrade the fibrous substances used by cattle, food digestion from the rumen stomach into the net stomach, the stomach of the net cow is composed of 4 gastric chambers, namely rumen, net stomach, double valve stomach and wrinkled stomach, rumen, the main function is to store feed and microbial fermentation, can help degrade the ability of fibrous substances and promote digestion, The main function of the net stomach is like a sieve, when the cow eats grass, it is inevitable to eat the wire, nails, etc., and the net stomach is the main one.

That's because the genes of cattle are different, in fact, it is also because the physical strength of cattle and other animals is different, so there is such a difference.

Because the physiological structure of a cow is different from that of other organisms, a cow has four stomachs that allow it to digest everything it eats.

Cattle have four stomachs: braided stomach, wrinkled stomach, rumen and net stomach, of which the wrinkled stomach can secrete gastric juice, which is equivalent to the stomach of a single-stomach animal and is a real stomach. Here's a detailed explanation:

The cow's stomach is composed of four parts, namely the rumen (first stomach, also known as the grass stomach), the reticulum stomach (the second stomach, also known as the honeycomb stomach), the valve stomach (the third stomach, also known as the valves stomach or louvered stomach), and the wrinkled stomach (the fourth stomach, also known as the true stomach). Clause.

The first, second, and third stomachs are collectively referred to as the forestomach, which has no gastric glands and cannot secrete gastric juice; The fourth stomach can secrete gastric juice, which is equivalent to the stomach of a monogastric animal.

The wrinkled stomach, also known as the true stomach, accounts for 8% of the total volume of the four stomachs, and its function is the same as that of the stomach of a single-stomach animal, which can secrete digestive juices and digestive enzymes.

Digestion of undigested feed in the rumen and rumen microorganisms that enter the true stomach along with rumen chyme.

The other three stomach functions of the cow:

1. The rumen accounts for 80% of the total volume of the four stomachs, and a large number of microorganisms grow and reproduce in it, and a large part of the feed is digested here.

2. The net stomach accounts for 5% of the total volume of the four stomachs, and its function is like a sieve, which retains the heavy objects such as nails and wires that are eaten with the feed.

3. The braided stomach accounts for 7% of the total volume of the four stomachs, mainly absorbing the water in the feed and squeezing and grinding the feed.

It can be digested effectively, which is what we learned from the texts of the third grade.

Stomach wrinkles

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 and has a real digestive effect.

It is the part where bacterial protein and rumen protein are digested, and chyme enters the small intestine through the pylorus, and after digestion, nutrients are sucked into the blood through the intestinal wall.

Development of the calf's stomach.

For the first 20 days, the anterior stomach accounts for 30% of the total gastric volume and the wrinkled stomach accounts for 70%. The ratio of four stomachs at 3 months of age is close to the size of adult cattle; Before 6 months of age, the stomach accounted for 70% of the whole stomach, and the wrinkled stomach accounted for 30%; At 12 months of age, it is close to the adult level.

Cattle are ruminants, and the most prominent feature of their digestive organs in terms of structure is that the cow stomach is composed of four parts: rumen, reticulum, valve stomach and wrinkled stomach. Among them, the rumen and reticulum have the largest capacity.

The stomach occupies the vast majority of the abdominal cavity and can hold 150 227 litres of feed, the contents of the stomach account for about 68% of the entire digestive tract, and each part of the stomach has a special function in the digestion of the feed.
