is the blood of a lizard? Blood is the fluid that flows through the blood vessels and heart of an animal. Many animals have blood. However, there is not only one color of blood, and the blood of different animals may show different colors. The blood of most vertebrates is red, the blood of humans is red, and in many people's minds, when they think of blood, they will subconsciously think that they are red. Although red blood accounts for the majority, not all lizards have red blood, and some lizards have green blood.
Specifically, the color of animal blood is closely related to the composition of blood. The blood of some lizards is green because their blood contains biliverdin, which is green, so the blood of lizards is green. The reason why most blood is red is that it contains more hemoglobin and iron ions. Because the color of these substances is red, the color of this kind of blood is red. Some lizards have hemoglobin in their blood, which is red. Similarly, human blood contains a lot of hemoglobin, which is also red.
above, some lizards' blood is red, while others are green, not blue, because their blood contains biliverdin, a green substance, or hemoglobin, a red substance. Although the blood color of lizards is not blue, blue is also one of the colors of blood. The blood of octopus, a common animal, is blue. Their blood appears blue because it contains hemocyanin and copper ions.
