Document Summary

In chapter 39 introduction to animal organization and physiology. Look like tiny column or cylinder when viewed form the side: nucleus is located near the base, these cells may be, simple: composed only of one layer of cells, stratified: composed of two of more layers. Simple epithelium is usually located in areas where materials must diffuse through the tissue or where substances are secreted, excreted, or absorbed. These are typical epithelial cells just to distinguish them from the true epithelia. The lining of the blood and lymph vessels endothelium. Connective tissue: the main function of connective tissues is to join together the other tissues of the body and to support the body and its structure, and to protect the under lying organs. In irregular dense connective tissue, the collagen fibers are arranged in bundles distributed in all directions through the tissue.

2. General questions about the digestive tract A. Mechanical digestion of all foods begins in the oral cavity. Describe how food is digested mechanically in the oral cavity. B. What is the scientific name for swallowing? Which portions of the pharynx does food pass through when swallowing? What is the function of the esophagus? C. Cells lining the stomach release hydrochloric acid (HCl). How does HCl assist in food digestion? How are the cells lining the stomach protected from being auto-digested by HCl? D. Carbohydrates, fats, and proteins must be broken down into their smallest subunits (AKA building blocks) in order to be absorbed through the epithelial lining of the small intestine. Name the building blocks of each of the major classes of nutrients: complex carbohydrates (AKA polysaccharides), fats, and proteins. E. About 99% of all nutrients are absorbed in the small intestine. Name the 3 portions of the small intestine. In which of these 3 portions does the greatest amount of nutrient absorption occur (think about the location and length of each segment)? Which type(s) of nutrient(s) is/are absorbed into blood capillaries? Which type(s) of nutrient(s) is/are absorbed into lymphatic capillaries? F. The last portions of the digestive tract are the rectum, anal canal and anus. Name the 2 muscular sphincters located at the anus. When the rectum fills, the defecation reflex is initiated. Describe the events that occur during the defecation reflex. Name the 2 sphincters located at the anus. Which sphincter undergoes involuntary relaxation during the defecation reflex? Which division of the autonomic nervous system causes this sphincter to relax and open? Name the sphincter that you control consciously to stop or initiate defecation.
