Adrenaline, released in anger, fear and danger, prepares the body for fight or flight. Oestrogen is the female sex hormone. Insulin controls blood glucose. Pheromones are chemical signals released into the air that attract partners through the sense of smell (strictly they act between individuals, not inside the body).
