Inflammation
Inflammation is your body's way of sending extra blood and healing cells to an injured area.
Think of it this way
When you cut your finger, your body acts like a kitchen crew rushing to a spill. Extra blood flows to the area, like water flooding a sink. Healing cells crowd in, like clean cloths piling up near the mess. The area gets red, warm, and swollen — that is the repair crew at work.
Explaining inflammation by grade level
When you get a cut, the spot turns red and puffy. That means your body is trying to fix it. Blood brings tiny helpers to clean up the hurt. The red, warm feeling goes away as you heal.
