❤❤❤❤❤❤❤
the bile is secreted by our liver .
it contains a lot of sodium bicarbonate which neutralizes the acid content of the food received from the stomach and makes it alkaline to enable the pancreatic and intestinal enzymes to act .
bile salts reduce the surface tension of fats and break them into tiny droplets for providing greater surface area for the action of enzymes
see the two reactions in the picture
AS WE KNOW THAT THE GASTRIC GLAND PRESENT IN THE STOMACH SECRETES HCL, THAT MAKE THE ACTION OF ENZYME TRYPSIN EASIER FOR THE DIGESTION OF CARBOHYDRATES. NOW WHEN FOOD COMES FROM STOMACH TO SMALL INTESTINE IT IS IN ACIDIC MEDIUM AND HAVE TO CONVERT INTO ALKALINE FORM FOR THE JUICES SECRETED BY PANCREAS AND ENZYMES SECRETED BY SMALL INTESTINE TO BREAK AND CONVERT THE PROTEINS, FATS, AND CARBOHYDRATES INTO AMINO ACIDS, GLYCEROL AND GLUCOSE. THOUGH THE FOOD IS CONVERTED INTO ACIDIC INTO ALKALINE BY THE ACTION OF BILE SALT FROM THE LIVER FOR THE FURTHER DIGESTION IN SMALL INTESTINE.
