Which of the following is an example of an exocrine function?

Question

BlackTom AI · Accepted Answer

To tackle the question, I'll examine what exocrine function means and then evaluate each option in that light.
Option 1: "A mother cuddles with her baby and bonds with it". This is a behavioral interaction that reflects social bonding, not a glandular secretion process. It does not involve exocrine activity, which requires secretion of substances through ducts to a target organ or outside the body.
Option 2: "Growth hormone causes the body to grow". Growth hormone is classically described as an endocrine function; it is secreted into the bloodstream by the pituitary gland and acts on distant tissues. Since it travels via blood rather than through a duct to a local site, this is not exocrine.
Option 3: "The pancreas secretes amylase into the small intestine". Here, the pancreas releases digestive enzymes into the digestive tract via ducts, delivering amylase directly to the small intestine for digestion. This is a classic exocrine function, as it involves secretion to an external environment (the intestinal lumen) through a duct.
Option 4: "All of these choices are examples of exocrine functions". Since options 1 and 2 are not exocrine, this statement is inaccurate. It would be incorrect to label all listed actions as exocrine.
In summary, the exocrine example among the choices is the pancreatic secretion of amylase into the small intestine, while the other options do not fit the exocrine definition because they involve non-exocrine processes such as bonding behavior or endocrine hormone release.
