Summary Introduction
Concept introduction: Food processing has several steps: ingestion, digestion, absorption, and elimination. The processing of food begins with the ingestion of food. Digestion is the second stage in which food is broken down into small molecules. The process of digestion involves the extracellular digestion and intracellular digestion. Food vacuoles are cellular organelles in which hydrolytic enzymes break down food.
Extracellular digestion takes place in the alimentary canal tube where large food particles are broken down into smaller particles. Absorption takes place mainly in the small intestine. The alimentary canal ends with the large intestine. This includes the colon, cecum, and rectum. The colon completes with the recovery of water that begins in the small intestine. The undigested food remains as feces, which is eliminated out of the body.

Perform library research about the selected disease, and explain its physiological effects on a person's body. Describe the relationship between specific foods/nutrients and the disease. Use the questions below to guide your response. Does research indicate that a lack of specific foods/nutrients increase a person's chance of contracting the disease? Are there specific foods/nutrients that should be avoided by an individual afflicted with the disease? How do specific foods/nutrients work physiologically within the body to help combat the disease? Evaluate nutritional recommendations to help combat the disease. Cite at least 3 credible references and present the resources in APA format on the References page.arrow_forwardVitamin D deficiency can often be found as a single nutrient deficiency, that is, in an otherwise well-nourished person. Which of the following is the most likely reason?

One of the most important starts when the food reaches the small intestine, this is sometimes also called the intestinal phase. Describe what happens if the food that reaches the duodenum contains a lot of fat and a lot of protein. The answer must include: Which different mechanisms are affected by the respective stimuli (fat and protein) and how (increases or decreases the activity). What cell type senses stimuli and how these cells react. Which different signaling pathways (including the signaling substances involved) control the different mechanisms that are affected by the respective stimuli. Feel free to draw.arrow_forward
