What is the purpose of the bile production in the liver?

Answer 1

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) lecithin

b) bile pigments

c)cholesterol

d) heavy metals like copper n zinc

e) drugs n bacterial toxins

It 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

Answer 2

Bile serves two important functions in the digestive system: # It neutralises the acidic stomach juices in the duodenum, providing ideal conditions for enzymes # To assisst enzymes even further, bile "emulsifies" fats ie. it splits fat into smaller globules, which provides a greater surface area for lipid-digesting enzymes to work on.

Answer 3

Functions of Bile juice

Bile juice reduces acidity of chyme.

It kills the germs and bacteria which are present in food.

It helps in emulsificaton of fats.

How Bile emulsifies fats

Bile is alkaline solution. Its molecules have dual nature (one end is attracted to water molecule while other is attracted to fat molecule). Thus its molecules remain in between water molecules and fat molecules (emulsification process).

If bile molecules were not present between fats and water, the fat molecules would be repelled by water molecules and be attracted to each other. The fat molecules would merge together because fats are insoluble in water. The merged fats would not be easily broken down with lipase (fat digesting enzyme).

So bile attractes the fat molecules and separate them from each other. It makes the fat digestion easier.

Answer 4

Bile is both, secretion and excretion from the liver. Bile contains the bile salts. Which are useful for emulsification of the fat. Bile excretes some waste products like bile pigments. Some large drug molecules like macrolide group of antibiotics are excreted through the bile.
