Hello friend greetings to you.

Injuryis any physical damage to the body caused by accident, cuts, weapon, violence, etc.

Surgery is a cutting into the body for the removal or readjustment, or repair of tissues and organs in the body system.

You have beautifully defined surgery and injury in two short sentences. I am really afraid of surgery. I can even see the wound or suture.

Your post is awesome. Best wishes for the contest.
