A Journey through the Digestive, Circulatory and Urinary Systems
My Fantastic Voyage: A Journey through the Digestive, Circulatory and Urinary Systems
My journey begins with the ingestion of a cheeseburger, fries, and root beer by a 55 year old man. I begin my trip in the gastrointestinal tract. While in the mouth, the food is masticated by the teeth and combined with saliva to moisten the bolus and begin digestion. Salivary amylase begins the breakdown of starches into smaller sugars and salivary lipase begins breaking down the fats (“Saliva,” 2013). We are then swallowed and peristalsis moves us down the esophagus towards the stomach (University of Leicester, 2001).
