T HE E SOPHAGUS By: Kristina Retherford, Jaidah Wilson, and Emmanuel Sinnathamby

E SOPHAGUS Muscular tube that connects throat/mouth to stomach Covered with pink tissue called mucosa 8 in long (20 cm) In adult about a 1 in. diameter

R OLE IN D IGESTION Takes food from pharynx and delivers to stomach Muscular contractions-peristalsis Peristalsis keeps food going toward stomach without needing gravity

F OOD D ELIVERY Receive from pharynx (throat) Already chewed and broken by the teeth Peristalsis pushes food towards the stomach where it continues the digestion process

E NZYMES AND C HEMICALS No enzymes/chemicals produced in esophagus Enzymes and chemicals from mouth travel through esophagus

C OMMON D ISEASES Heartburn- causes stomach contents to reflux and this can cause coughing/hoarseness or sometimes no symptoms Esophagitis - inflammation of esophagus which can cause swallowing problems and scarring in esophagus *Many diseases can follow esophagitis such as esophagus cancer, restriction of esophagus, and esophageal ulcers*

R ARE D ISEASES Achalasia- lower sphincter of the esophagus doesn’t relax properly which causes difficulty swallowing and regurgitation of food Esophageal Cancer- cancer in esophagus which is very serious which can be caused by smoking, drinking, and chronic reflux

COMPARISONS Normal esophagusEsophagus with cancer AchalasiaEsophagus with ulcers

T ESTS pH monitoring Acidity of acid in esophagus Esophageal Manometry Strength and pattern of muscle contractions
