MadSci Network: Anatomy |
It has been a struggle this year to get my students to believe that blood is red, especially when I hear that one of their other science teachers is telling them that it is blue. When I asked how she could think blood was blue, her response was that when blood loses the heme group, it becomes blue. But even still, there isn't much that I can think of in blood that would ever turn it blue, no matter if it lost the heme or not. I am fully aware of that fact that iron whether oxygenated or not, is always red. But what happens when the heme group is lost? Thank you!
