1. Accessory Organs of the Digestive System

2. Teeth Know: 4 types & functions
Humans have 32 (most have their 4 wisdom teeth removed)

4. Salivary Glands
3 pairs
Parotid glands
Submandibular
Sublingual
Secrete saliva (mix of mucus and serous fluid) into mouth
Moistens food into a mass  bolus
Contains salivary amylase  begins to break down starches
Has lysozymes and antibodies that kill bacteria

5. Mumps Inflammation of the parotid salivary gland
Swelling, tenderness
Incidence has decreased since MMR vaccines

6. Pancreas
Makes enzymes that break down all food types (carbs, proteins, fats)
Enzymes secreted in duodenum in alkaline fluid
Produces hormones: insulin and glucagon that go into the blood

7. Liver
Largest gland
Digestive function – produces bile (goes to duodenum via bile duct)
When bile is not needed stored in gallbladder

8. Liver Hepatitis – inflammation of the liver
- Often due to viral infection spread in contaminated water, needles, or blood-blood contact
 Cirrhosis – chronic inflammation of the liver; becomes hard and fibrous
often caused by drinking too much alcohol
also caused by hepatitis

10. Gallbladder
Sac on inferior surface of liver that stores bile (inc. concentration)
Gallstones – too much water removed from bile & cholesterol crystallizes
Jaundiced – bile pigments back up and skin/eyes become yellow
