It’s amazing how the human body was designed. It can and does heal itself, and wound granulation is evidence of this miracle.
I have seen a wound growing new tissue, and it is a wondrous thing. The body responds rapidly to protect its members, no matter how small. The wound could be on a pinky toe, and granulation would still occur just as quickly.
When I injured myself by falling off a bicycle, my knee had a gaping wound. Fascinated by the healing process, I took photos of every stage, from the time I got home with the fresh wound, through granulation, all the way to maturation.
I used the photos to teach my children about the resilience of the human body. Having a visual really helped me get my point across, and it kept them interested.
