Why is blood red in color? | #aumsum #kids #science #education #children

It's AumSum Time. Why is blood red in color? Because every day it bathes using red paint. No. Our blood mainly consists of a liquid called plasma, red blood cells, white blood cells and platelets. However, the color of our blood is basically because of red blood cells. Each of the red blood cells contains hemoglobin. Hemoglobin is an iron-rich protein. When hemoglobin binds with oxygen, the interaction between them gives our blood its red color. Moreover, like human beings, not all animals have red colored blood. This is because the blood of some animals such as octopuses, spiders, etc. Has hemocyanin instead of hemoglobin. Hemocyanin is a copper-containing protein. When hemocyanin binds with oxygen, their interaction gives the blood a blue color. The blood of some lizards has biliverdin instead of hemoglobin which give their blood a green color.
