What is the function of the Esophagus?

• The chemical breakdown of materials by acid and enzymes; mechanical processing through muscular contractions

• Muscular propulsion of materials into the esophagus

• Dehydration and compaction of indigestible materials in preparation for elimination

• Transport of materials to the stomach

Which Organ is not a major part of the digestion system?

• Oral cavity

• Teeth

• Pharynx

• Small intestine

Which organ is not an Accessory to the digestive system?

• teeth

• gallbladder

• stomach

• pancreas

What is the purpose of Peristalsis?

• Moves a bolus along the length of the digestive tract

• Longitudinal muscles ahead of bolus contract

• Wave of contraction in circular muscles

• Circular muscles contract behind bolus

What does the gallbladder store?

• Stomach acids

• Bile

• Pancreatice juices

• Bicarbonates

What is the function of digestion?

• – Is the release of water, acids, enzymes, buffers, and salts

• Movement of organic substrates, electrolytes, vitamins, and water

• Makes materials easier to propel along digestive tract

• The chemical breakdown of food into small organic fragments for absorption by digestive epithelium
