The Function of the Gall Bladder
Because fat cannot be dissolved in water, a special system has evolved for 
its digestion and its absorption through the intestinal wall. Bile is an 
essential factor in this, since it contains substances that allow fats to 
be emulsified. It also stimulates the secretion of an enzyme concerned 
with the breakdown of fats. Bile is secreted by the liver and stored in 
the gallbladder until needed. When fat is eaten, this stimulates the 
gallbladder to contract and bile flows down the cystic duct, into the 
common bile duct and through the ampulla of Vater into the intestine. As 
well as acting as a storage vessel, the gallbladder concentrates the bile 
within it by removing water through its wall
Nervousness, or stress, cause the body to withdraw blook from the 
digestive tract and shuts it down, diverting energy to the muscles in 
anticipation of fight or flight.
The color of the feces simply suggests the dietary habits, as well as 
color, texture, smell and amount of water present.
The nature of feces is a good indicator for health and, in days past, it 
was studied in depth by doctors in absence of modern tests, like blood 
Generally, feces should be dark brown and not be excessively hard or soft, 
nor should there be any blood, mucus or water in it.
These are signs of illness and should be taken seriously. Also, diarrhea 
is an indicator of dietary problems.
Any change in health or diet can trigger a change, and the change can be a 
warning sign.
Consult your doctor if you have more specific questions.
thanks for asking.
