It is a form of physical (mechanical) digestion. No chemical reaction is taking place (ie. change in type of molecules). The bile simply breaks the lipids up into smaller globules to increase surface area.

∙ 9y agoThe word is emulsification. Bile emulgates fats; divides the globules into smaller droplets and keeps those from bubbling together again so other digestive juices can better work their magic on them.

∙ 12y agoBile is a rather clever tool in digestion of fats. Its role is emulsification which means to break down into little droplets. You see fats (oils mostly) do not mix with water as it is hydrophobic. Bile has two parts to it a hydrophilic head (likes ot be in water) and a hydrophobic tail (does no like to be in water). The tails of the molecule stick into the droplets of fat while the heads float in the water and so hold the fat in spehicle droplets in suspended in the water. Interestingly this is the same mechanism by which soap works to remove dirt from the body. The benefits of this action of bile are two fold. Firstly the droplets of water are small enough to be transported around whereas the single mass of fat is not. Secondly the total surface area of the droplets if much greater than that of the single mass meaning more enzymes can act on it and so the fat can be digested faster.

Bile salts aid in the absorption of what?
fats
Where does the bile duct lead to and what substance does it carry?
The bile duct carries bile from the gallbladder and the liver to the duodenum. Bile helps to break down fats in the food we eat.
What is the purpose of the bile production in the liver?
Bile(produced by the liver) breaks fat particles into smaller ones.it has 3 main functions-1. DIGESTIVE FUNCTIONS- bile salts, major constituents of bile, help in fat digestion in 2 ways-a) detergent/ emulsifying action- they reduce surface tension of globules breaking them into smaller droplets, thereby increasing surface area.b) activation of pancreatic lipase- which splits neutral fats into fatty acids n monoglycerides.2. ABSORPTIVE FUNCTIONS-a) absorption of fats n fat soluble vitamins. by forming water soluble complexes of digestive products of fat, called micelles. (hydrotropic action)b) absorption of minerals like iron n calcium.3. EXCRETORY FUNCTIONS-excretion of-a) lecithinb) bile pigmentsc)cholesterold) heavy metals like copper n zince) drugs n bacterial toxinsIt acts as a detergent in the body. It breaks down fats.To emulsify fats. Emulsification means to break the fats up into little globules to increase the surface area so the pancreatic lipase enzymes can act on them more efficiently.there are 5 functions of bile ....1. neutralization- as bile neutralizes the acidity of chyme,,..2.activation-bile activates pancreatic and intestinal juices secretion...3.emulsification-it emulsifies fats into small particles...4.hydrotrophic action- bile salts make insoluble fats to mix up....5.absorption- bile helps in absorption of fats and fat soluble vitamins....The function of bile is lipid emulsification. This is the breakdown of lipid droplets and it is necessary to increase the surface area of lipid that is available for enzymatic action. As a result of the increased lipid emulsification, more lipids can be absorbed across digestive epithelium.To emulsify (chew up) fat molecules for easier digestion
What hormone causes the gallbladder to contract and release bile into the small intestine?
Cholecystokinin is the hormone that causes the gall bladder to release stored bile. It is made in the small intestine and secreted when fatty food goes from the stomach into the small intestine.
What relationship exists between bile and the gallbladder?
Bile is stored, not created, in the gall bladder before it is secreted into the duodenum to emulsify fats.No
Is bile a physical or chemical reaction?
The process of bile is a physical one because it does not contain any enzymes that breaks down any fats. Lipase is the enzyme that breaks down fats but bile is only an emulsifier, which is a physical process, that combines bile with the fats.
What thing help in emulsification of fats?
In the small intestine of digestive system the lipids are emulsified by the action of bile from liver.
Is bile used for chemical or mechanical digestion?
it is use for chemical digestion as it emulsifies fats.
Is the bile duct involved directly or indirectly in mechanical or chemical digestion?
Indirectly in chemical digestion by the release of stored bile into the small intestine. The bile then emulsfies fats.
Bile salts aid in the absorption of what?
fats
What bile digest?
Fats
What happens in digestion when bile duct is blocked?
if bile duct is completely blocked then the bile juice and bile salt will not be secreted and the digestion of fats will not be done. the food coming from the stomach is acidic and has to be made alkaline for the pancreatic enzymes to act. bile juice from liver accomplishes this in addition to acting on fats. fats are present in the intestine in the form of large globule which makes it difficult for enzymes to act on them. bile salts break them down into smaller globules increasing the efficiency of enzyme action. alll this cannot take place if the bile duct is blocked.
What is the chemical action of the liver?
bile is produced by the liver to help break down fats
What makes bile to help break up fats?
you liver makes up bile which helps break down fats.
Does bile help break down proteins and amino acids?
Bile breaks down fats into smaller particles that can be more easily digested.
What do chewing and the action of bile have in common in the digestive system?
They both break down a certain thing. Bile breaks down fats while chewing breaks down carbohydrates in simple sugar
What are bile acid sequesterants?
Bile acid sequesterants are drugs that act by binding with the bile produced by the liver. Bile helps the digestion and absorption of fats in the intestine. By blocking the digestion of fats, bile acid sequesterants prevent the formation of cholesterol.
