How to distinguish between human blood and animal blood Do humans have blood types and animals have

Methods for distinguishing human blood from animal blood:

1. Taste. The most striking feature of the taste is that the fishy smell is particularly strong. Due to the limitations of life experience, people have been exposed to sheep blood, pig blood, and chicken blood. Sheep's blood has a hot and baked taste. Pig blood smells. Chicken blood. Human blood is the salty smell.

2. Viscosity.

Animal blood is a bit thicker than human blood and darker in color than human blood.

3. The salt content of the blood.

The blood of animals contains less salt than human blood, which means that human blood is saltier (of course, taste sensitivity is the first condition).

4. Coagulation speed.

Human blood is more likely to clot than animal blood.

5. Anti-human hemoglobin colloidal gold test strip test.

The most portable is the anti-human hemoglobin colloidal gold test strip, which is similar to the pregnancy test strip in principle and operation. The test strip is easy to operate, has high sensitivity, and the result is available in about 2-5 minutes, and if it is positive, the test object is human blood. No additional instrumentation is required.

Most insects have colorless blood, and some Antarctic fish also have colorless blood, earthworms.

It is rose-colored, the snail is milky white, the blood of black, mussels, and snails is blue, the spider is blue-green, some insects also have green blood, and the blood of some creatures on the bottom of the sea can change color. Red because it contains iron, blue because it contains copper in the blood, green because it contains vanadium, white because it contains zinc, and colorless because it does not contain it. Except for the above-mentioned types of animals with obvious blood colors, there is basically no clear way to identify red-blooded animals, because the composition of human blood and animal blood is the same - plasma, blood cells, inorganic salts, oxygen, metabolites, hormones, enzymes and antibodies, etc.

The latter substances can be detected differently during laboratory tests, and the biggest difference should be hormones and antibodies. In the laboratory test, it can also be screened according to the blood type, but the knowledge of blood type is very complicated, and I can't explain it clearly, which probably means that the substance containing A is blood type A.

Substances containing B are blood type B.

By analogy, animals also have different blood types, there are five types of dogs, fifteen types of pigs, ten types of horses, ten types of cows, up to forty species, and many other animals have their own blood types, which can be identified in turn. Mammal.

Only white blood cells.

There are nuclei, red blood cells, and platelets.

There is no in it, birds also have nuclei in their red blood cells, insects do not have red blood cells but there will be interstitial fluid, reptiles forget, it is different anyway, I hope it can be pointed out later. It is said that there is also that kind of chromogenic antibody now, and I don't know if it's human blood or animal blood when it's stained with blood on the ground, and if it's human blood, it will immediately change color, and this thing seems to be very popular in **. <>

Human blood smells of rust, I can't say how pig blood feels, but it definitely doesn't taste like human blood. The blood of the sheep is very thick, and the smell is full of smell. Ox blood only remembers that the taste is very strong.

It is not very difficult to distinguish between human blood and animal blood, because the physiological structure, living environment and other factors of humans and animals are different after all, so they will not have the same strong taste as animals. Also, a lot of human blood is also very fishy, but it still feels sweet and fishy. Don't ask me how I know the smell of rust, if your home is in a particularly cold part of the north and you have a big iron gate, you know.

If you're lucky, you can understand the smell of rust and blood at the first time. Give it a try! It's sweet!

1. Eat and see 2. Take it for testing.

Many animals are divided into blood types: the common human has ABAB, the rare AB type has the Rh-negative blood type, and animals also have it, and some are different from humans, and humans have found that the blood types of animals are also complex through the study of animal blood.

Human blood can be roughly identified as red, the only difference is that some people's blood is bright red, some people are dark red, and some people are dark red, and the difference in these colors is only a matter of how much oxygen is in different human hemoglobin. In the animal world, the color of blood is colorful, and red blood is just one of them. In addition to red blood, there are also blue blood, green blood, blue blood, rose red blood, light blue blood, and colorless blood.

Why is there so much blood of different colors in the animal kingdom? The blood of any animal is made up of plasma and blood cells. The color of the blood is determined by the hemochromatin present in the plasma or blood cells.

Different hemochromatins have different colors.

Hemoglobin survives in the human body in the form of hemoglobin, which is abundantly present in the cytoplasm of human red blood cells, and its main role is to transport oxygen and part of carbon dioxide. In the blood of different animals, hemoglobin presents different ways of existence depending on the animal species. Hemochromatins like earthworms, mussels, spiders, etc., are dissolved in plasma; Whereas, hemochromatin in vertebrates is found in the red blood cells of blood cells.

One of the most special ones is insectsInsect blood is hemochromatin-free. This is because the stomata in the insect allow the oxygen in the air to diffuse directly into the body tissues, and the carbon dioxide in the body can also be excreted through the microtrachea, so the hemochromatin, which is involved in oxygen delivery, loses its original value.

The blood group of primates can be determined by anti-A and anti-B serum. Chimpanzees have all blood type O or A, orangutans have type B, gorillas have type B and A, and gibbons have blood types A, B, and AB. Lower primates do not have antigens in red blood cells, but secrete ABO antigens in their saliva.

Most of the Old World monkeys have blood type A, and the New World monkeys also have blood type A, but some have antigens like B in their saliva. Antigens similar to human M have been found in some primates, such as those with M and N blood groups in chimpanzees, and Rh antigens have also been found in primates.

There are blood types, such as chickens, ducks, pigs, dogs, salmon, as well as cows, horses, tigers, birds, etc., these animals have blood types, for example, horses have 4 blood types.

Animals are divided into blood types like humans, mammals generally have blood types, such as: lions, dogs, monkeys, orangutans, etc., and turtles and frogs also have blood types.

Some animals have blood types, and animals with blood types, such as chickens, dogs, salmon, cows, sheep, tigers, birds, these animals are all blood types.

When people get sick and go to the doctor, many times the doctor asks us to do a blood test, but have you ever wondered what is the difference between human blood and animal blood?

There is no difference in appearance between human blood and the blood of most animals, but under the microscope the difference is great. The following few ** will show us some details.

Figure 1: Aquatic animals (grass carp) have large and oval red blood cells, nuclei, and large and abundant platelets, so aquatic animals rarely die from excessive blood loss due to injury.

Figure 2: Poultry (domestic chicken) red blood cells are approximately round, nucleated, and lymphocytes are visible.

Figure 3: Mammalian (domestic pig) red blood cells are relatively close to human red blood cells, without nucleus, and lymphocytes are easily visible. This image shows pig blood contaminated with bacteria.

Figure 4: Human red blood cells and increased lymphocytes. Normal human red blood cells are concave and disc-shaped, with a faint stain in the middle.

Figure 5: Blood cells from lymphocytic leukemia patients.

You need a specially tailored human blood chromogenic antibody. If this substance is sprinkled on the blood, if it is human blood, the antibody will specifically bind to it and develop color. Thank you.

Some. In the case of our common animals, the molecular structure of antigens on the surface of red blood cells in blood is also different. For example, there are three blood types in felines, including type A, type B, and type AB; Dogs have 8 blood groups, labeled as erythrocyte antigens (DEA and 7); There are also 8 main blood types of horses, that is, antigen types include A, C, D, K, P, Q, U and T; The situation of dairy cows is more complex, with 11 main ears to antigen (a, b, c, f, j, l, m, r, s, t and z); The blood type of pigs is mainly AO blood type, which is somewhat similar to human ABO, but pigs do not have type B blood, and 90% of pigs have blood type A.

The blood type represents the different antigen structures on the red blood cells in the blood of animals, and the matching type needs to be considered when the animal is transfused, otherwise it will cause agglutination and thus cause harm. Therefore, it is of concern to scientists studying blood, immunity, and antibody antigens. In the production of porcine hemoglobulins in the feed sector, there is no agglutination of blood groups for large-scale storage of blood.

Therefore, the sedan chair will only pay attention to the quality, freshness, color and other quality control indicators of the blood itself.

With fresh pig blood as raw material, the company adopts international advanced technology and production technology to produce high-quality blood cell plasma protein powder products, which has become a shining star in the feed industry.

There are common ABoabs in humans, and rare AB types of Rh-negative blood types, and animals also have them, and some are different from humans, and humans have found that the blood types of animals are also very complex through the study of animal blood. For example, there are 5 blood types for dogs, 6 for cats, 9 for sheep, 9-10 for horses, 15 for pigs, more than 40 for cats, ZW for silkworms, O for apples, and plants for blood types.

Cattle have 40 blood types In addition to humans, higher animals such as monkeys, orangutans, elephants, and dogs also have blood types, and even turtles and frogs can also find traces of blood types. Through the study of animal blood, humans have found that animal blood types are also complex. For example, there are 5 blood types for dogs, 6 for cats, 9 for sheep, 9-10 for horses, 15 for pigs, and more than 40 for cattle.

Apples are O type and plants also have blood types. Shigeru Yamamoto, a Japanese policeman, once found that plants also contained blood-type substances in the process of investigating the case. This is an unprecedented discovery in blood typology.

Actually, this is not surprising. The chemical composition of a blood-type substance is a special type of sugar, which is not only found in people, but also in plants, so plants also have blood types. Shigeru Yamamoto conducted in-depth research and found that apples, pumpkins, strawberries, and camellia were O-type, coral trees were B-type, and grapes, plums, and single-leaved maple were AB types.

A person's blood type is determined by the genes of the parents, and the blood type is determined from the day the fetus is conceived and does not change throughout life. However, with the development of science, there are various examples that show that some people's blood type can also be changed. Qiu Jiulie, a 13-year-old boy who received the first hematopoietic stem cell transplant for minors in Shenzhen, was saved by transplanting his sister's bone marrow, and his blood type changed from the original type B to type A like his sister.

Explanation of terms Blood type: What we generally call "blood type" refers to the "ABO-style" blood type, which was discovered by the American physiologist Ronterstey. One of the factors that determine blood type is something called a "blood substance", which is often mixed with red blood cells in the blood.

If a person does not have any blood-type substance in his body, then he is type O. If it contains a type A substance, it is type A. If it contains a B-type substance, it is B-type.

If it contains both type A and type B substances, it is type AB.

Yes, there are not many people who check with humans, and some have H-type and O-type ones.

Yes, it is similar to humans, and there are many H-type, O-type, and K-type.
