The gall bladder provides bile salt.
The gall bladder is a small pear-shaped organ that is located at the abdomen inferior to the liver.
This organ stores and releases the bile salt produced from the liver.
The bile salt is released through the bile duct into the duodenum of the small intestine.
The bile salt is use to emulsify fat thereby aiding it's transport across the intestinal membrane.
Therefore, the gall bladder provides bile salt that aids in transport of lipids across the intestinal membrane.
