Need help on two questions on the digestive system?I have 2 questions that I just cannot figure out on the digestive system.
First: In what structure of the digestive system are all of the enzymes necessary for complete digestion of food first found?
Also: What is the first duct that carries bile?
Thanks

The small intestine contains enzymes that deal with various foods; the saliva partially digests starches, and pepsin in the stomach breaks down proteins.
The hepatic bile duct first carries bile; it joins with the duct from the gall bladder to form the common bile duct.

the FIRST place that enzymes needed for digestion are found is in the MOUTH. Amylase is the enzyme in your spit that begins digestion even before the food reaches the stomach.

1 The question don't seem to be very clear to me...is it asking of where food is first found? Or is it asking where major digestion takes place?
Well...i'll answer both. (:
Digestion first begins in the mouth. It has salivary amylase to break starch down into maltose.
The smalll intestine it where major digestion takes place. In the small intestine, many important enzymes are present. Pancreatic juices and intestinal juices are present, carrying the enzymes.
Pancreatic juices includes amlyase, trypsin and lipase. Intestinal juice contains maltase, lactase, sucrase, erepsin and lipase. Enterokinase is also present in the intestinal juice to convert trypsinogen to the active form, trypsin.
#2 There is only one duct that carries bile--- the bile duct. (:
