Answer 2

hi mate,

===>>here is information about digestion

digestion begins in the mouth, well before food reaches the stomach.

====>>When we see, smell, taste, or even imagine a tasty meal, our salivary glands in front of the ear, under the tongue, and near the lower jaw begin making saliva (spit).

====>>Once filled with food, the stomach grinds and churns the food to break it down into small particles.

===>>It then pushes the small particles of food into the first part of the small intestine, called the duodenum. The small intestine is where most of the digestion and absorption of our food takes place.

===>>The small intestine is where most chemical digestion takes place. Most of the digestive enzymes in the small intestine are secreted by the pancreas and enter the small intestine via the pancreatic duct.

===>>.. The three major classes of nutrients that undergo digestion are proteins, lipids (fats), and carbohydrates.

===>>Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine.

===>> As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.

===>>Also It Important That The Digestive Processes. The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation.

===>>The first of these processes, ingestion, refers to the entry of food into the alimentary canal through the mouth.

I hope it helps you.
