  • Why is blood red in color?

  • Coz everyday it baths 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 color 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.

  • Hold on guys.
