Pancreas

Anatomy and Physiology of the Pancreas


Pancreas

• An elongated gland extended to duodenum-spleen
• Having a head, body and tail that has exocrine portion that secretes insulin and glucagons
• Seen at retroperitoneal

A. PARTS

• Pancreatic islets- originate in endocrine that secretes insulin and glucagons.
• Pancreatic duct- unites with common bile duct to unfilled the duodenum.
• Acinar gland(acini)- a branch of exocrine that secretes digestive enzymes.

B. FUNTIONS


• Exocrine secretions has bicarbonate;

 That neutralized acidic juice or chime
 Stops pepsin digestion
 Provides proper function of the pancreatic enzymes.
 Helps in digestion of all classes of food.


• Proteolytic enzymes

 Trypsin
 Chymotripsin
 Carboxy peptidase

These enzymes digest protein that came from the stomach and pancreatic amylase for the digestion of carbohydrates from the oral cavity.

• Pancreatic enzymes

 Lipases- for lipid digestion
 Nucleases- lessen DNA and RNA from its nucleotide component.
 Secretin- produced watery pancreatic solution that has bicarbonate. Acidic chyme is the stimulus for the production of secretin.
 Cholecystokinin- stimulates the pancreas for the production of enzyme rich solution, which stimulated by the presence of fatty acids and amino acids from the duodenum

C. ENZYMES PRESENT IN THE PANCREAS

 Alpha cells- secretes glucagons
 Beta cells- secretes insulin.

It must be difficult to maintain this blog with all your assignments and exams plus the lectures you have to attend to. Not everyone has a computer of their own and an internet access for that matter. I do hope that you can give some of your time to work on this blog. Someone may benefit from the knowledge that you share on your post.

The color is cool to the eyes and the post itself is easy to read. Some pictures may help and the links as what your teacher told you would have an impact on your blog.
