How is the blood I shed blue, please everyone, thank you

My blood is black because my blood is dry Your blood is blue, and I can only sigh and say that you have a very poor ability to distinguish colors.

No, blue-bloods are rare. It is generally the object of medical school that is willing to study. In reality, it seems that there are also, I once saw it in a scientific exploration book, and it seems that it is still a certain family in Finland.

Also, the Blue Bloods are creatures from Wesleyan sci-fi "Blue Bloods". They are from Saturn, (Titan), and when they encounter emotional changes such as nervousness, sadness, happiness, etc., their faces turn blue, just like we earthlings blush.

In the game? In reality, it seems that only the people on the Pamir Plateau and Shennongjia in China may not be red blood.

There are blue-blooded people, don't be sad, you should be proud.

Wow, it's up to the Blue Blood Man to get you to do the experiment.

Among the arthropods, there is an animal called horseshoe crab, which has remained unchanged since its appearance more than 400 million years ago, and is called by scientists"Living fossils".Interestingly, the horseshoe crab's blood is blue and clotted upon contact with bacteria, making it widely used in the medical and food industries as a reagent to test for the presence of bacteria.

A king squid and horseshoe crab have blue blood, while oyster and cuttlefish have green blood. The color of blood is determined by the elements contained in hemochromatin. The copper-containing element is called hemocyanin, which makes the blood blue; The barium-containing element is called hemochlorvidin, which makes the blood green; The iron-containing element is called hemoglobin, which gives blood its red color.

Because barium and copper are less oxygen-transporting than iron, blue-blooded animals are more common in early lower animals. For example: arthropods, molluscs.

Are you in here?

Why are blood vessels blue?

Because your heart has changed: it is not surprising that the blood is blue! You're no longer human, it's just that you're an alien! The phrase literally means blue blood, but actually means someone who was born noble. There are many legends about this!

Normal people's blood contains more iron, and more copper contains blue blood.

Because you're a Martian, hehe.

In the hemolymph of the two largest phyla of invertebrates - arthropods and mollusks (cephalopods and ventral pods).

There is a hemocyanin that is blue when it is deprived of oxygen, and their blood is blue.

The most "common" is squid.

I asked the fish, and the fish said, "You live in the sea;

I asked the bird, and the bird said, "You used to live in the sky."

But the blood of the fish that lives in the sea is red, like a disturbance to you;

Birds flying in the sky, blood is red, like you.

And my blood is blue.

I don't want to have blue blood, I want my blood, like you.

So, I took the slow mold and raised the knife to my heart.

Stab away. See my blue blood.

Bubbling and surging like a melancholy river for you.
