Write the functions of the following: a. Bile juice b. Mucosa c. Pancreas
Answers
Answer:
Explanation:
Pancreatic juice consists of alkaline (chiefly bicarbonate) fluid and enzymes; 200–800 ml is produced each day. The enzymes, such as trypsin, lipase, and amylase, are essential for the digestion of most of the protein, fat, and carbohydrate in the meal.
Bile helps to emulsify fats (increasing surface area to help enzyme action), and thus aids in their absorption in the small intestine. It also makes the acidic food coming from the stomach alkaline, so as to enable the action of pancreatic enzymes
The oral mucosa has several functions. Its main purpose is to act as a barrier. It protects the deeper tissues such as fat, muscle, nerve and blood supplies from mechanical insults, such as trauma during chewing, and also prevents the entry of bacteria and some toxic substances into the body

HLO HERE IS UR ANSWER
A. BILE JUICE
Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine. Many waste products, including bilirubin, are eliminated from the body by secretion into bile and elimination in feces.
B.MUCOSA
The mucosa is the innermost layer, and functions in absorption and secretion. It is composed of epithelium cells and a thin connective tissue. The mucosa contains specialized goblet cells that secrete sticky mucus throughout the GI tract.
C.PANCREAS
The Pancreas and Its Functions. The pancreas is an organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body's cells. The pancreas has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar.
