What is the definition of Richards Blood Cells?

Ah, Richards' blood cells! They're like the unsung heroes of our circulatory system, but with a side of mischievous mingled in their veins. These cells are the tiny warriors of our body, fighting off germs, delivering oxygen, and ensuring our organs get a constant supply of life-giving goodness. But let's not forget the darker side - sometimes, these blood cells can be a bit too friendly with the bad guys, causing all sorts of health issues, like chronic fatigue syndrome or a constant state of 'Why am I even alive?' dread.
