Final answer:

Step-by-step explanation:
The subject of this question is Medicine.
Three days after surgery, some common changes that can occur in the body include becoming stiffer, atrophy, and fatty infiltration of tissues.
When a person undergoes surgery, there is usually a period of immobility or limited movement afterwards. This lack of physical activity can lead to stiffness in the muscles and joints. Additionally, the body may experience atrophy, which is the loss of muscle mass and strength due to disuse. Lastly, during the healing process, there can be an increase in fatty infiltrates in the tissues surrounding the surgical site.
