Question

4. What products from the liver and pancreas in the cat are secreted into the duodenum? What macromolecules are digested in the small intestine?

Answer 1

• liver is one of the largest organ in the body.
• function of liver in cat include:-

1. food subunit storage,
2. detoxification of poisons comming into the blood stream from gut,
3. processing of food sub units
4. dietry fat are breakdown into fatty acid by releasing of bile ,which is produced by liver and released into duodenum.

• bile is stored in gall bladder and released into duodenum through bile duct.

• pancreas have both endocrine and exocrine function
• insulin in secreated from pancreas.
• hormones have effect on many macromolecules such as carbohydrate, fat and protein.
• exocrine portion help in protein breakdown into aminoacids.
• pancreas also produce glucagon, somatostatin, watery solution containing digestive enzyme.
• exocrine acini produce proteolytic enzyme including trypsinogen,chymotrpsinogen,proelastase, and procarboxypeptidase A and B.
• these enzymes are in inactive form, activated by enterokinase which will convert trypsinogen to trypsin.
• cholecystokin increases pancreatic secreation that results from food in duodenum.
