How does the splitting of cells connect to when the body heals?

• Damaged cells can split in order to stop themselves from dying

• Nearby undamaged cells can split in order to fill gaps or repair damaged tissues

• Cells can split in order to create a scab and stop bacterial infections

• Cells can split open to release healing chemicals into the body
