(Shark Attack)

As blood is being lost, blood cells try to go and replace what was lost in the leg.

Immune: Sends white blood cells over to fight off unwanted bacteria from the bleeding leg.

Respiratory: Victim breathes harder from trying to swim away from the shark and from blood loss making them weaker so oxygen is being carried out everywhere for the leg to try and slot bleeding out.

Endocrine: Adrenaline is released, needing more oxygen from the body to swim away from the shark faster.
