What is the function of the following digestive organ: Small Intestine

• Storage and regulated release of bile

• Re-absorption of water,

  further digestion especially of

  carbohydrates by symbiotic

  bacteria, plus formation and storage

  of feces

• Digestion of lipids,

  carbohydrates, proteins and nucleic

  acids, neutralizing stomach acid,

  plus absorption of nutrients

• Churning and mixing with secreted

  water and acid which kills foreign

  bacteria and other pathogens in

  food, plus initial stages of protein

  digestion

What is the function of the following organ: Stomach

• Voluntary control of eating and

  swallowing. Mechanical digestion

  of food by chewing and mixing with

  saliva, which contains lubricants and

  enzymes that start starch digestion

• Churning and mixing with secreted

  water and acid which kills foreign

  bacteria and other pathogens in

  food, plus initial stages of protein

  digestion

• Movement of food by peristalsis

  from the mouth to the stomach

• Secretion of surfactants in bile to

  break up lipid droplets
