digestive system

• teeth break down food mechanically , sailiva contains amylase (an enzyme)
• the stomach contains hydrochloric acid & enzymes that chemically break down food
• the liver produces bile , which is stored in the gallbladder before going to the small intestine
• bile emulsifies lipids to form droplets , increasing their surface area
• the pancreas secretes amylase , which break down starch into glucose in the small intestine
• water is absorbed into the blood stream in the large intestine
• nutrients like glucose are absorbed into the bloodstream by the villi in the small intestine
