Dear student
 Blood is red because it is made up of cells that are red, which are called red blood cells. ... Each haemoglobin protein is made up of subunits called hemes, which are what give blood its red colour. More specifically, the hemes can bind iron molecules, and these iron molecules bind oxygen.
