The Digestive System Case Study Example
The Digestive Tract
Part I: Parts of the Digestive Tract/System
The digestive tract starts at the mouth. This is the first step of digestion. When one takes the first bite, food begins the digestion process through chewing. Chewing breaks down the food into more soluble pieces. This also increases the surface area for which the digestive enzymes can work on the food in the latter stages of the digestion process.
The oesophagus is located in the throat near the windpipe (trachea). This is the second stage of the digestion process. This part receives food from the Continue reading...

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).

The Digestive System From The Esophagus To The Anus Critical Thinking Examples
The esophagus is simply a tube that transports food to the stomach after being swallowed from the mouth (Cleveland Clinic, 1). Swallowing ensures that epiglottis in the throat is closed hence the food moves down the esophagus, preventing it from moving down through windpipe to the lungs. The contraction and relaxation of the muscles within the esophagus enables the food to move down hence this serves as its anatomical adaptation. This paper traces the pathway of food from the esophagus to the stomach, indicating the anatomical adaptations of each organ involved (Cleveland Clinic, 1).
This is the initial stopping Continue reading...
Metabolism And Digestion Of P Falciparum Critical Thinking Examples
Plasmodium falciparum is the parasite responsible for the deadly disease, malaria. The parasite is transmitted through the injection of sporozoites into the human blood stream. These sporozoites are transported in the blood stream to the liver. The sporozoites invade the hepatocytes and differentiate into merozoites. The merozoites invade the RBCs of the host; starting the blood stage of infection. The trophozoite stage ingests and degrades approximately 80% of the hemoglobin in the host cell. The hemoglobin is broken down into peptides due to enzymatic action by a metalloprotease and cysteine and aspartic proteases. Haematin is first released as a Continue reading...

Digestion And Metabolism Essay
Digestion is the mechanical and chemical break down of large food particles to smaller molecules that can be taken up into the blood (Winfred, 2005). The breakdown of large food starts in the mouth, through chewing, and goes all the way to the anus. The presence of saliva in the mouth that contains saliva amylase helps mechanical breakdown of food into bolus. The bolus then enters the stomach through the esophagus by a wavelike movement called peristalsis to the stomach. The churning of food and mixing of food begins in the stomach where both hydrochloric acid and gastric juice Continue reading...
