How are our bodies able to differentiate between cuts, burns, punctures, bruises, scratches etc through pain and how do they heal differently?
In: Biology
This is ELI5 so I won’t get into a ton of details. Essentially, on a cellular level the damage from all of those things is similar and ends up having similar effects. Remember the powerhouse of the cell? If those injuries are severe enough it shuts down the mitochondria and then the cell dies. There are then a specific set of steps that happen after that cell death called inflammation that cause those dead cells to be cleaned up and the area repaired. Depending on the amount of initial damage the repair can be easy or hard, and scars may form.
