Mercury combines with bile and can cause bile from the gallbladder to become more alkaline, providing a favorable environment for parasites. These parasites can plug up the hepatic or bile duct so that needed digestive and other enzymes from the gallbladder, liver, and pancreas are not released.
The extremes of temperature seen on Mercury are the result of the lack of atmosphere. What little atmosphere Mercury has is made up of oxygen, sodium, helium, hydrogen and potassium. It is simply too small to have the gravity that would allow it to hold on to a proper atmosphere. Scientists refer to Mercury's atmosphere as its exosphere.
