Today, James was playing basketball in his neighborhood. He began to sweat a lot.
When sweating, the immune system filters the toxins out of the body to help maintain homeostasis.
James slipped and fell and scraped his knee in the process. The blood had bled through her pants so she had to go home.
When James got home, he changes his shorts and saw that there was an inflammation in his knee. This was caused by the bacteria in the wound.
Although Jamie had no idea what was going on with his knee, his immune system was working hard to bring his knee back to its original shape.
A couple days have past and his wound has started to heal and formed a scab. The immune system produces antibodies to the damage tissue and engaged in the process of the wounded heal.
