Question

What is the function of a) bile juice b) pancreatic juice c)saliva​

Answer 1

Bile helps to emulsify fats (increasi ng 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.

Pancreatic juice is an alkaline fluid (pH 8) containing enzymes, pro-enzymes and electrolytes for the digestion of carbohydrates, proteins, fats and nucleic acids; 1200–1500 mL/day is secreted from the exocrine acini of epithelial cells, which comprise 98% of the pancreatic mass

The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

Answer 2

Answer:

a)Since bile increases the absorption of fats, it is an important part of the absorption of the fat-soluble substances, such as the vitamins A, D, E, and K. Besides its digestive function, bile serves also as the route of excretion for bilirubin, a byproduct of red blood cells recycled by the liver.

b)Pancreatic enzymes break down food in the small intestine. When food enters the duodenum, it is deluged with pancreatic juice, which is defined as an alkaline secretion of the pancreas containing enzymes that aid in the digestion of proteins, carbohydrates and fats.
