Jessica went for a run at the field one day. She started to perspire excessively.
This aided her skin in removing toxins from her body and cooling her down to keep her body temperature stable.
Jessica stumbled and fell while jogging as she approached the finish line. She saw that her knee had been scratched. She had to go home since blood had leaked through her clothes.
She changed her jeans when she arrived home and saw that her knee was inflamed. The germs got into the wound and created this.
Jessica, on the other hand, had no idea what was wrong with her knee. Her immune system was working overtime to restore it to its previous state.
Because her knee was inflamed, her body's macrophages acted as scavengers, removing dead cells and cellular debris.
Jessica's wound began to heal and create a scab a few days later. This resulted in the formation of a scab. The b-cells, which generate antibodies to injured tissue and participate in wound healing, created this.
T-cells and killer t-cells release interleukin and tumor necrosis, which boost the immune system's defense response.
