Topic: Digestive System Aim: Describe the role of accessory organs in digestion. Do Now: Practice questions HW:

Identify the digestive organ described. Where the digestion of protein begins. Where mechanical digestion begins. Site of water absorption. All chemical digestion is completed here. Where the chemical digestion of starch begins. Where feces is formed. Pushes food into the stomach. Where the absorption of nutrients occurs. Lining is protected by a mucus layer.

Accessory Organs Organs that HELP in digestion Food DOES NOT pass through these organs

Salivary glands: release saliva - Helps begin starch digestion

Liver Stomach Gall bladder Small Intestine Pancreas 5

1.Liver

Produces bile travels to small intestine

2.Gall Bladder

Stores bile until needed

Secretes pancreatic juice into SI

Review: Identify the digestive organ described. Where the digestion of protein begins. Where mechanical digestion begins. Site of water absorption. All chemical digestion is completed here. Where the breakdown of starch begins. Where bile is stored. Releases many enzymes into the SI. Where feces is formed. Pushes food into the stomach. Where the absorption of nutrients occurs. Lining is protected by a mucus layer.
