Last step of digestion is occur in small intestine.. During gastric digestion, food is allowed to enter small intestine by pyloric sphincter muscle present at the junction of stomach and small intestine. Finally it relaxes and allow the semidigested food to enter in small intestine in small amounts. here, food is mixed with three digestive justices :
✴️ bile juice of liver
✴️ pancreatic juice of pancreas
✴️ intestinal juice of intestinal glands.
⏩⏩⏩bile juice neutralises the acidity of the food coming from the stomach and provide alkaline medium and emulsifies larger fat globules into smaller fat droplets to increase the surface area for digestion by increasing the efficiency of fat-digesting enzymes of pancreatic juice. But is non - enzymatic digestive juice so has no chemical action on food.
⏩pancreatic juice contains a number of enzymes like trypsin, pancreatic amylase and pancreatic lipase enzymes which digest the peptones into peptides, starch into maltose and isomaltose and fatty acids
⏩⏩intestinal juice also contains a number of enzymes like amino peptides, intestinal amylase, maltose isomaltose and lipase enzymes which hydrolyse peptides to amino acids, starch to maltose, maltose to two glucose, isomaltose to two glucose and fats to fatty acids and glycerol.
So.... small intestine is the site of the complete digestion of carbohydrates, protine and fats.
