Because bile salts are important lipolytic enzymes, fat digestion relies on which of the following accessory organs?   Small intestine   Pancreas   Liver   Salivary glands

LARGE INTESTINE Chemical digestion events/processes (what are they and for which nutrients? Name/describe any enzymes involved.): Mechanical digestion events/processes (what are they and for which nutrients?): Absorptive events/processes (what are they and for which nutrients?): Role of accessory organs? (which organ(s) and how do they contribute)? Additional details:

Which nutrient(s) are NOT enzymatically digested before they are absorbed? (Check all that apply). Check All That Apply Fats Carbohydrates Proteins Vitamins Minerals

Which of the following best describes the process of peristalsis smooth muscle contractions that move food through the alimentary canal a common cause of loss of appetite, fatigue, and dehydration voluntary control of the rectal sphincters regulating defecation the transport of nutrients to the liver through the hepatic portal vessel a process of fat emulsification in the small intestine

As you may know, Homer Simpson loves his donuts. So lets help Homer understand how his donut is processed from beginning to end. To do this you will need to 1. summarize the digestive system by identifying the gastrointestinal tract organs and their functions as the donut moves along the track. To do this you will need to identify 2. the function of the mouth and what compounds are broken down in the mouth and how (describe the chemical digestion); 3. The function of the stomach, describe chyme, the role of the stomach in mechanical digestion, chemical digestion (how, describe the chemical digestion and enzymes), and absorption. Why is it necessary for the stomach contents to be so acidic? How does the stomach protect itself from digestion? State the cells that secrete hydrochloric acid, pepsin, and intrinsic factor and the functions of each secretion; 4. Explain how small intestine absorption is assisted by circular folds (plicae circulares), villi, and microvilli; and describe…

The organs making-up the “tube” share a similar histology.  The muscularis mucosae is the tissue layer that comes in contact with the food passing through the lumen of the tube, and is…

Mention the locations where the digestion and absorption of carbohydrates and proteins occur. Give examples of the chemical agents involved in the digestion of carbohydrates and proteins.

You eat a cheeseburger. Describe the process by which the protein, carbohydrates and fats are broken down. Include the locations of each step.   Explain how the final products of digestion are absorbed (separately for fat, protein and carbohydrates. Include where this happens, and where they go after.   Explain what ingredients in the cheeseburger provide each type of nutrient.
