The human body is made up of billions of tiny cells that work together to keep us alive and functioning properly. Every day, these cells are constantly dividing, growing, and repairing damaged tissue to keep our bodies running smoothly. In fact, the average person's red blood cells last for about 120 days before they need to be replaced. This incredible process happens without us even thinking about it, a testament to the amazing complexity and resilience of the human body.
