Its the mouth.........cause saliva breaks down some amount of starch into simple sugars. but its not a very major site..............
The first major site of chemical digestion in frog is their stomach
the major part of the chemical digestion is the HCL (hydro chloric acid)
mechanical and chemical digestion
Not sure what you mean by '3 types of digestion', but there are three major food groups (carbohydrates, proteins, and fats), and each has a different method of digestion by the digestive system.
mechanical and chemical , d po q sure :)
In the formation of the embryo the first and perhaps most important physical differentiation is gastrolization, which is the formation of the alimentory canal.
The small intestine is the organ responsible for both chemical digestion and absorption of nutrients from food. Enzymes and bile break down the food, while nutrients are absorbed through the small intestine's lining into the bloodstream for distribution to the body's cells.
Salivation is the function that helps digestion by keeping the mouth moist and comfortable when you chew and swallow. The salivary glands secrete saliva for this purpose. The saliva also moistens the food (a physical change), and begins to chemically alter the food with enzymes (a chemical change).
It is the small intestine, although the word small is hardly appropriate. It is around 30 feet long. ________ Hmmm. I think it would be the mouth. It may not be very large, but I believe it is a major organ. In any event, there is the stomach that would certainly be named before the small intestine.
The stomach serves too major roles in digestion. It is a place where chemical digestion takes place with stomach acid helping to break down food. It is also a place where mechanical digestion takes place. The stomach muscles expand and contract to crush and grind food.

The major source of lipase in the body is the pancreas. Pancreatic lipase is an enzyme produced by the pancreas and plays a key role in breaking down fats in the small intestine during the digestion process.
