Indicate the site of the following activity in the digestive system (mouth, esophagus, stomach, small intestine, large intestine, liver, gall bladder, pancreas).
1.breakdown of cholesterol by formation of bile acid
2. principal site of formation of folic acid and vitamin K by resident bacteria
3.diarrhea usually oocurs because of malabsorption of water and electrolytes from this organ (the major site of absorption of both)
4.gastrin is secreted from this organ
5.heartburn occurs when the acidic contents of the stomach “back up” into this organ
6.this organ is described as having both exocrine and endocrine function
1. The breakdown of cholesterol by the formation of bile acid occurs in the liver. To get this answer, one can refer to a basic anatomy or physiology textbook, or perform an internet search using keywords such as "cholesterol breakdown bile acid liver."
2. The principal site of formation of folic acid and vitamin K by resident bacteria is the large intestine. This information can be found in a microbiology textbook, or by conducting a search using terms like "site of folic acid and vitamin K formation in the digestive system."
3. Diarrhea usually occurs because of malabsorption of water and electrolytes from the small intestine. This can be deduced by understanding the role of the small intestine in the digestive process. A textbook or a search using keywords like "site of water and electrolyte absorption in digestive system" will help confirm this.
4. Gastrin is secreted from the stomach. This fact can be found in basic anatomy and physiology textbooks or by searching for information on hormones secreted by the stomach.
5. Heartburn occurs when the acidic contents of the stomach "back up" into the esophagus. This is commonly known, but can also be found by searching for information on heartburn or gastroesophageal reflux disease (GERD).
6. The organ described as having both exocrine and endocrine function is the pancreas. This is well-known anatomical information and can be found in any anatomy textbook or through a quick search using keywords like "exocrine and endocrine function of pancreas."

I urge you to look up these hormones.
Google is a great help for finding information.
