A day in the life of a red blood cell

My job that I circulatory do is quite complicated, and tiring. I pick up oxygen from the lungs and after finding my way around your body though all the confusing capillary routes, when I reach wherever my destination is, somewhere in your tissues or muscles, I clear out the oxygen. Then I pick up the carbon dioxide in your body and travel back through your veins back to your lungs for your to breathe it out.

A real diary would start as when I woke up, but that would be lying as I never sleep, even when you do I have to constantly re-do the cycle. I do not rest and I am constantly on a fitness program. But it definitely benefits. I travel extremely fast and my disk-shape makes me flexible for passing through your thin capillaries, no trouble. This disk-shape also means i have a large surface area, perfect for diffusion.

My haemoglobin I contain means my favourite foods are anything with iron, which is another reason why a healthy diet is essential to keep you going. You need haemoglobin, otherwise you could get anaemia.
