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 tests. 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.
