Solution

Bile juice:
Bile is a digestive juice formed within the liver and is stored within the gall bladder until it's needed within the small intestine where it is needed.
Bile is an alkaline greenish-yellow fluid and contains salts which helps to emulsify or break the fats molecules into small droplets.
It makes the acidic food coming from the stomach alkaline so that pancreatic enzymes can act on it.
