The digestive system and enzymes

• The mouth

  Teeth chew the food

  Salivary glads in the mouth secrete amylase enzyme in saliva to begin carbohydrate digestion
• Oesophagus

  A tube that connects the mouth to the stomach
• The stomach

  Has muscular walls that churn food into smaller pieces

  It produces pepsin, a type of protease that breaks down proteins

  it produces hydrochloric acid to kill bacteria and to provide optimum ph for the pepsin to work in
• The liver

  Produces bile, crucial for neutralizing stomach acids and emulsifying fats into smaller droplets

  The bile is stored in the gall bladder
• The pancreas

  Produces protease, carbohydrase and lipase
• The small intestine

  It produces protease, carbohydrase, and lipase

  This is where digestion is completed

  Where the broken down nutrients are absorbed into the bloodtsream
• The large intestine

  The large intestine absorbs excess water from digested food

  Waste is eventually moved to the rectum as feces and exits the body through the anus
