Does human blood have any other color? What color is human blood

There's green, but it's not natural! There may not be one in China, but there are many people abroad who suffer from a migraine disease, which is different from the headache we know in China. Their migraine is a neurological and psychological disease (our headache doctor said that in addition to brain diseases such as tumors, most of them are psychological or fatigue-induced, and Asians may not be more likely to suffer from them).

For this disease, you need to take a medicine that contains thiocyanic acid, you must know that the sulfur atom and hemoglobin are combined, and the blood will be green, so if you eat too much of this medicine, it will dissolve into the body, and the blood will turn green. Even the organs inside, including the brain, can turn green and pear-colored or black!

I have heard that the blood of people who live to be 100 years old is pink, and some people have said that people with genetic mutations have blue blood!

Why is blood red? Because the blood contains a large amount of hemoglobin, which is red blood cells, it has the function of transporting oxygen and nutrients. This is the main function of blood, and without this function it would not be blood without hemoglobin.

Not only people, but all animals with blood on their bodies have red blood and almost the same effect.

Maybe there's a blue one, that's what Unsolved Mysteries says.

Live past 100 years.

Most of them are pink blood.

The blood of leukemia patients is whitish.

It was reported in the tabloids.

Blue blood. and green-blooded people, but whether it's true or not no one knows.

Human blood. It's black.

Yes. Human blood is red. The blood of frogs is colorless.

It's red. The red color of the blood is different, the red color of the blood comes from the hemoglobin in the red blood cells, which is bright red when the oxygen content is high (arterial blood), and dark red when the oxygen content is low (venous blood).

Usually blood donation is drawn from venous blood, so the outside ** is dark red. If the blood contains more methemoglobin or other hemoglobin derivatives, it will be purple-black.

Plasma (or serum) appears transparent and yellowish because it contains a small amount of bilirubin; If it contains chylomicrons, it is milky white and cloudy; If hemolysis occurs, it appears as red plasma.

Because blood is made up of plasma and blood cells, the main components of plasma are water, antibodies, and hormones, and it is light yellow in color. Blood cells include red blood cells, white blood cells, and platelets. The main color of red blood cells is red.

Junior high school biology should do such an experiment, after the blood is placed in the peace, there will be a stratification phenomenon, which is the stratification of blood cells and plasma, each layer presents a different color.

The main reason for hemoglobin blood redness Hemoglobin is composed of hemoglobin and four polypeptide chains, and after connecting the rocks and ferrous ions inside through weak bonds, the arterial blood is bright red because the hemoglobin molecule absorbs the short-wave light in the dark red blood of metabolism and diffuses carbon dioxide into the hemoglobin in the red blood cells. It accounts for about 25% to 30% and appears blue-purple due to the lack of oxygen in the blood to absorb longer wavelengths of light, so it appears dark red when mixed.

Blood is mainly made up of plasma (a yellow-brown liquid) and blood cells, which are made up of red blood cells, white blood cells, and platelets. The blood is red mainly because of the color of the red blood cells, which are red because of the presence of iron in the body. Only a small fraction of the iron in the human body is contained in muscles, liver, spleen, and other organs and tissues, and most of it is concentrated in hemoglobin, which is the red blood cells in the blood.

Iron-containing hemoglobin turns red blood cells. Red blood cells make up almost half of all blood, and a small drop of blood contains millions of red blood cells. It is because of the presence of so many red blood cells in the blood that the blood takes on a red color.

Hemoglobin is a porphyrin derivative with an iron ion embedded in the center via a coordination bond. At the right oxygen concentration, ferrous ions reversibly bind to an oxygen molecule with histidine residues, but do not change their valence. In particular, once one subunit of hemoglobin carries an oxygen molecule, it changes the entire configuration, making each of the other three molecules bind more easily than the previous one and release oxygen just as quickly.

We vertebrates thus acquire an efficient metabolism that allows us to move quickly and vigorously while maintaining our body shape.

Because the main component of blood cells is red blood cells, red blood cells contain hemoglobin, and hemoglobin contains trivalent iron ions, iron atoms, and the color of trivalent iron is red, so the red cells in blood cells are red blood cells, so blood is red.

This is because the most abundant blood in the human body is red blood cells, and red blood cells are made up of hemoglobin, which is blood red, so blood is also red.

It is because there is a protein in the blood, which is what we often call hemoglobin, and when hemoglobin encounters oxygen, it turns scarlet.

Because there is a heme compound in the hemoglobin of the blood, it is also because of this compound that the blood looks red.

This is because there is a lot of hemoglobin in the blood, so the color displayed is red.

Because there are red blood cells in the blood, red blood cells contain hemoglobin.

Red. Blood is a red, opaque, viscous fluid that flows through a person's blood vessels and heart. Hemoglobin is bright red when it contains more oxygen (arterial blood) and dark red when it contains less oxygen (venous blood).

Among the many indicators reflecting the rheological properties of blood, blood viscosity, plasma viscosity, red blood cell aggregation and deformability occupy an important position, and have been widely used in clinical testing. From the perspective of rheology, in addition to the above-mentioned commonly used indicators, the thixotropy and viscoelastic indexes of blood can better reflect the non-Newtonian characteristics of blood, and can also provide more valuable information for the clinical diagnosis of certain diseases.

Blood in the human body is red, except that arterial blood is bright red and venous blood is dark red.

Red blood cells carry oxygen from the lungs to tissues, where oxygen and carbon dioxide are exchanged. Every red blood cell is filled with hemoglobin – a protein that contains iron. In the lungs, hemoglobin chemically combines with oxygen to form oxyhemoglobin, a chemical that is bright red.

When blood carries oxygen into the tissues and then returns to the lungs through the veins, it is dark red in color, close to purplish-red.
