Do fish have blood type 10, is the blood of humans the same as fish

The common human has a b o ab, the rare one has the AB type of Rh negative blood type, animals also have ah, some are different from humans, and humans have found that the blood type of animals is also very complex through the study of animal blood. For example, there are 6 blood types of cats, 9 blood types of sheep, 9-10 blood types of horses, 15 blood types of pigs, more than 40 blood types of cattle, silkworms are ZW type, apples are O type, and plants also have blood types.

So, of course, fish have blood types, but they are classified differently from humans.

The blood of most Antarctic fish is not red, but grayish-white, due to the absence of hemoglobin. Fish species in the Southern Ocean are more abundant in certain waters south of the Antarctic convergence zone, especially in the waters near islands.

The blood and cell fluid of cold fish contain glycerol and polysaccharides, and the coagulation point is very low, even if the fish body is frozen, the liquid in the blood vessels and tissues will not freeze and destroy the physiological structure of the fish"Defrost"Then it was a live fish again.

The amount of urea in the blood, in sharks, in rays, has a lower concentration of salt in their bodies than in seawater.

Blood type refers to the specific antigen that can be heritable on the surface of blood cells (note that not only red blood cells) are present, and blood cells have blood type, including fish.

The blue blood horseshoe crab is pronounced hòu, the initial is h, the vowel is òu, the tone is the fourth tone, the mouth is slightly open when pronounced, and the tongue is slightly against the jaw. The upper part of "horseshoe crab" is the same as "learning", and the lower part is "fish", so some places call horseshoe crab "learned fish".

The Chinese horseshoe crab is a strange creature with blue blood, living in shallow seas, and is found in Zhejiang, Fujian, Guangdong, Guangxi, and Hainan in China, and Xiamen, as a city along the Shengcheng Sea in Fujian Province, is naturally the main habitat of the horseshoe crab. The most surprising thing is that the blood is blue in color, which has high medicinal properties. However, due to the indiscriminate fishing and killing of human beings, the number of Chinese horseshoe crabs has decreased dramatically, and even a large number of Chinese horseshoe crabs have been put on the human table.

Habits of horseshoe crabs:

The physiological structure and living habits of horseshoe crabs have allowed them to develop the ability to overcome the existential crisis brought about by the extreme environment and become the "living fossil" of the ocean. Fresh bait horseshoe crabs are most popular to eat, such as razor clams, oysters, small trash fish in seawater, etc., among which razor clams and oysters are the best.

The feed intake of the Chinese horseshoe crab is greatly affected by the water temperature, which is between 20 and 28'e, the appetite is the most vigorous; The water temperature is at 20'Below e, the amount of food intake gradually decreases, low dust at 15C, almost no feeding, therefore, the amount of bait should be determined according to the change of water temperature and how much remains of the last bait, generally adult horseshoe crabs eat 30 40 grams of oyster meat or small trash fish per day.

Palpiaceae is a Myleus fish (in the same family as piranhas, but without sharp teeth).

The picture below shows the Myleus Schomburgkii, commonly known as the thick line silver plate.

Distributed in the middle and lower reaches of the Amazon River and the upper Orinoco River basin in South America, it can reach a length of 42 centimeters, inhabits the bottom and middle waters, and can be used as a food fish and ornamental fish, and its strong teeth can cause trauma.

Sometimes they show a nervous side, in the case of excessive environmental changes, such as rapid changes in water quality, sudden irradiation of strong light and artificial collision or sudden approach, etc., will make them show uneasy tension and urgent reactions, small splashes, large may have the tragedy of jumping the tank, this is the situation that the owner should pay attention to. When feeding, you will see them agile and fast, and even a little exaggerated picture of grabbing food.

Herbivorous silverfish have a gnawing habit and often eat the roots of aquatic plants in the wild, or in the season when the river is flooding and the water level is high, they will eat the fruit hanging from the river, but because the pit and shell are indigestible, they usually eat only the pulp and excrete the indigestible parts. When raised in captivity, it can be used as the main feed for small and medium-sized particles with floating and semi-floating properties, and can also be fed with frozen bloodworms, breadworms and green leafy vegetables.

It's not the same! Humans are homeothermic animals, and fish are cold-blooded animals!

Blood circulation in fish.

It is closed, its heart is relatively simple, located near the gills, and consists of an atria and a ventricle. The gills of fish are made up of many lobules with many capillaries. Through its huge area, it absorbs the dissolved oxygen in the water into the bloodstream.

The power of the gills is very high (some fish can use 70% of the oxygen dissolved in water), which may be indicative of the fish's red blood cells.

The power is high.

Bony fish. There is a cap on the outside of the gills, and the fish opens its mouth and opens the gill cap at the same time as it breathes, so that the water is sucked into the mouth, and the membrane on the gill cover prevents water from flowing in this direction. When the mouth is closed, water can be squeezed out of the gill slit by a mechanism at the front of the mouth.

Cartilaginous fishes do not have a gill cover, and they must constantly swim with their mouths open to allow water to flow through their gills.

Some bony fish, such as eels, have very small gill slits and their gills can also remain moist for a while on land, so that they can breathe on land for a while. Some other fish that are more or less amphibious have other respiratory organs: some fish can breathe oxygen directly from the air, some fish can breathe air into the intestines, and their smooth intestinal walls can absorb oxygen from the air.

Some fish have protruding organs that can be used as respiratory organs, and some fish have swim bladders.

Connected to their intestines, their fish bubbles.

It can also be used to assist in breathing oxygen in the air. Lungfish.

The protrusions of the intestine have evolved into the lungs.

According to scientists, 1,000 years ago, my blood was the same as that of a mermaid, and now fish are almost non-existent.

The big ingredients are the same, and the details are much worse.

According to biologists, different animals have different blood types. For example, rodents have AB blood group, carnivores have OAB blood group, fish have A blood group, and so on; Humans are advanced animals with blood types O, A, AB, and B.

A+ is an Rh-positive blood group A.

Positive and negative refer to the Rh blood group system, with positive being denoted as + and negative being denoted as -.

Most Chinese are positive, and the least common is Rh-negative AB type, which is a rare blood type. There will be a record in the blood bank, so that the blood source can be found in the first time.

Extended Materials. Classification of blood groups:

ABO blood group is a blood group that divides blood into 4 types based on the presence or absence of antigens A and B on the red blood cell membrane. Only antigen A is type A on red blood cells, only antigen B is type B, and if there is both A and B antibodies, the principle is AB, and those without both antigens are type O. People with different blood types have different antibodies in their serum, but they do not contain antibodies against their own red blood cell antigens.

For example, blood serum with type A contains only anti-B antibodies. Among the people of all ethnic groups in China, blood type A, B and O blood types account for about 30% each, and AB type only accounts for about 10%.
