1. which of the following is not a function of the gi tract?

secretion of enzymes
ingestion of food
elimination of waste
transport of digested food
all of the above are functions of the gi tract.

Explanation:

1. The gastrointestinal (GI) tract is a continuous tube from the mouth to the anus. The mouth, small intestine, large intestine, and rectum are all parts of this tube. The liver is a gland that aids in digestion but is not part of the continuous tube of the GI tract.
2. The functions of the GI tract include ingestion of food (taking in food through the mouth), secretion of enzymes (e.g., in the stomach and pancreas to break down food), transport of digested food (through peristalsis in the intestines), and elimination of waste (undigested material as feces). So all the given options are functions of the GI tract.

Answer:

1. Liver
2. All of the above are functions of the GI tract.
