describe in detail the importane of digestive juicies in digestive system . highlight the role of pancreatic juice

Dear student

Please refer the solution below for the said query
 

Following are the glands associated with the digestive system and their secretions:

ORGAN GLAND SECRETION ENZYMES ACTION OF ENZYME
Mouth Salivary gland Saliva Salivary amylase Breaks down starch to sugar
Stomach Gastric glands Gastric juices
1. Pepsin
 
2. HCl
 
3. Mucus
1.Breaks down protein-peptones
2. Kills-germs, create acidic medium.
3. Protect the walls of stomach from the action of HCl
duodenum
1. Liver
 
 
2. Pancreas
 
 
1. Bile juice
 
 
2. Pancreatic juices
_
 
 
1. Amylopsin
 
 
 
2. Trypsin
 
 
 
 
3. Lipase
 
Emulsification of fats, create alkaline medium
1. Breaks down starch to maltose
2. Breaks down protein to amino acid
3. Breaks down emulsified fats
Small intestine
(site of complete digestion)
Intestinal glands
Intestinal juices
(recives bile & pancreatic juice
1. Erepsin
2. Maltase
 
CONVERTS:
Protein--amino acid
Sugar—glucose
 

Pancreatic juice contains proteases, lipase, nucleases, amylase, water, mucus and sodium bicarbonate. Proteases are enzymes that digest proteins, lipases digest lipid or fat, nucleases digest nucleic acids and amylases digest starch. Mucus lubricates and water dilutes the food substances. Sodium bicarbonate increases pH for optimum enzyme functions.

Hope this information clears your doubt about the topic.
