Storyboard Text
- Ouch! I just fell out of a tree and cut my knee. Will I be okay?
- You know, Son, a lot of very cool things are happening in your body right now to heal those cuts.
- Well, let me explain a little bit...
- Like what?
- Platelets join together to clot the bleed site.
- Meanwhile, pathogen-associated molecular patterns are detected by blood and lymph cells.
- Cytokines activate and go out to warn cells that pathogens are near, kind of like Paul Revere!
- Cytokines tell: - Uninfected cells to reduce protein production- Infected cells to undergo self destruction-Immune cells to fight the invading pathogen
- Redness, swelling, and pain begin as leukocytes and fluid fill the wound site.
- Neutrophils start the fight with invaders and call for more help.
- Macrophages eat and dispose of the invaders while sending the lymph nodes antigens.
- Once macrophages bring antigens to the lymph nodes, the dendritic cells create a plan of attack with the T-cells and B-cells.

- Cytotoxic (Killer) T-cells multiply and respond with force to help destroy the invading germs.

- The pathogen was destroyed and the cleanup process begins.

- As the leukocytes and other cells leave, swelling and pain goes down.

- See you all next time!
- Fibroblast cells create new blood vessels to fill in the void. This is what creates a "scab".
- During the last stage of healing, a tissue called "collagen" remodels the cuts and adds durability, strength, and a scar.
- And before you know it...
- My knee is healed!
- Thanks for the explanation, Dad! I didn't know our bodies are that cool!
- You're very welcome, Son!
