Science digestion system

• Mouth -breaks up food particles
• Pharynx- swallows the food
• Salivary Glands- saliva moistens

  and lubricates food
• Esophagus-muscular tube that moves food to stomach
• Liver -breaks down and builds up many biological molecules
• Gallbladde -stores and conrntrates bile
• Stomach -stores and churns food pepsin digest protein
• Pancreas -Hormones regulate blood glucose levels Bicarbonate
• Rectum -stores and expels feces
• Large intestin -reabsorbs some water and ions form and stores feces
• Small intestine -complete digestion mucus protects gul wall absorb nutrients
• Anus -opening for elimination of feces
• Bile duct- connects gall bladder with small intestine
• Gallbladder- store bile from liver
• Liver- detoxifies the body, produces bile to aid fat digestion, regulates blood sugar level
• Gallbladder -store bile from liver
• Pancreas- secretes enzymes that break down carbohydrate protein and fats into simple sugars amino acids and fatty acid respectively
• Stomach -churn food into chyme
• Stomach- mix food with gastric juice containing hydrochloric acid pepsin and intrinsic factor
• Pancreas -produce enzymes that break down carbohydrate protein and fats
• Salivary glands- secrete saliva which contains amylase an enzyme that breaks starch into maltose
• Salivary glands -secrete saliva which contains amylase (enzymes)
• Small Intestines- site where most absorption occurs
• Rectum- temporary storage area for waste material
• Large Intestines- absorbs water and electrolyte
• Small Intestines -absorption of nutrients
