mariarad [96]

The intensity range would be 60-80%.

A high resting heart rate is indicative of an inefficient heart or possible arrhythmia. Physical activity assessments should begin after the client has been screened and resting measurements have been assessed.  Moderate intensity exercise uses energy 3 - 6 times that of resting metabolism, which equates to 3 -6 METs.

Where do bile and pancreatic enzymes enter the small intestine?
BartSMP [9]

Answer:

The correct answer is duodenum

Explanation:

Bile is a digestive enzyme that is secreted by the liver which is temporarily stored in the gall bladder and pancreatic enzyme is released by the pancreas. The bile is secreted to the small intestine through the common bile duct and the pancreatic duct joins the common bile duct just before ampulla of Vater which opens in the first intestinal portion which is duodenum.

So bile and pancreatic enzymes enters the duodenum region of the small intestine and after getting in the small intestine it digests the complex macromolecules into simpler and smaller form which can be absorbed through the intestinal epithelium.
