Welcome my students. Today we are going to see the topic that is Dallysian in humans. So let's continue topic. In last session we have seen Dallysian taking place in food and stomach. After stomach the food enters into the deuda. The deuda is the first part of the small intestine. Time enters through the pyrolyxpenta into the tiny spots. What happens in the deuda in the secretions of the liver and pancreas are poured and secretions of liver is the bile and secretion of pancreas is the pancreatic juice. The bile helps to neutralize the acidic time. Now at this point proteins and carbohydrates are the only partially digested and the lipid digestion has not begun. Now here what happens? Carbohydrates get converted. The proteins and carbohydrates are partially digested. While lipid digestion does not take place and lipid is mainly digested by the uncreatic lipis in which lipids are converted into fatty acids and aggressor. Next comes the two ducts enter the deuda one entering the gallbladder. That is the liver as I have told you another draining the exocrine portion of the pancreas. Next comes the pancreatic juice. Now pancreatic juice contains sodium bicarbonate which neutralizes the acidic material from the stomach. This contains water, sodium, stalls and various enzymes. Now the action of various enzymes present in the pancreatic juice like pancreatic amylase in digest starch into maltose which means on alkaline medium. Next trypsin and chemotrypsin digest the proteins to peptides. Like peptides produced in the stomach they are specific to certain amino acids not all of them. So they therefore produce peptides. So proteins are converted into peptides. While lipids enzyme which digest the glycerol and fatty acids. Next comes the liver. The liver produces bile which is stored in the gallbladder and sent to the deudaenum through the duct. Now in liver mainly what happens? Bile juice produced in the liver it is neutralized as a dechloric chym and this bile juice is yellow, green liquid which is composed of water, cholesterol, bile salts. So this bile emulsifies fats that means it separates the small droplets using bile acids. So they can mix with the water and can be acted upon various enzymes. So this bile also contains bile pigments. These are the products of the breakdown the hemoglobin removed by the liver from the old red blood cells. And this brownish color of the bile pigments imparts the characteristics of the long-for-to-the cases. This is the main reason. So these bile pigments are there but there are no enzymes especially. These bile pigments, bilirubin and bilirubin are mainly produced as the roots of breakdown of hemoglobin. Now what happens is the other functions of the liver. If the detoxifies is the blood from the intestine that received via the hepatic portal. As you can see here and the liver stores the glucose as glycosine mainly. Now what happens mainly? Glucos is not continuously used as for energy purpose. Many times when there is no need of energy, this glucose is stored in the form of glycosine. And this glycosine gets a breakdown into glucose when the energies need it. It produces various types of blood proteins. Now minor ammonia produced by the dilation of proteins is converted into lectopsych compound which is called as urea in the blood. So urea is also produced in the liver. So students in this session we have seen the digestion taking place in the diodenum as well as in the liver. In further session we will have more detail. Thank you.
