Final answer:
Bile and pancreatic juice are necessary for fat digestion. Bile emulsifies fats, and pancreatic juice contains enzymes that break down these emulsified fats. The absence of either can lead to incomplete fat digestion, causing fatty stools.
Explanation:
Fatty stools, a condition known as steatorrhea, can result from the absence of bile or pancreatic juice. These elements are crucial for the emulsification and digestion of fats in our diet. The gall bladder secretes bile, containing bile salts, that emulsify the fats into smaller droplets, increasing the fats' reaction rate with pancreatic lipase enzymes. Meanwhile, the pancreatic juices contain lipases, enzymes that break down lipids. These elements collectively facilitate absorbance of the fats in the small intestine.
When either pancreatic juice or bile is missing, due to reasons like gallstones obstructing the bile duct, fat digestion is incomplete, and an excess of fat is excreted in the stool resulting in fatty stools. Also, the liver is unable to remove bilirubin from the blood resulting in jaundice. Thus, both bile and pancreatic juice are essential for healthy lipid digestion and absorption.
