the colon—rectum‚ and anus” (NDDIC). Digestion begins in the mouth‚ where the food is cut and ground into small pieces. As the food is broken up‚ the first phase of chemical digestion occurs as saliva‚ which is secreted from the salivary glands. Amylase‚ contained in the saliva‚ begins the breakdown of starches into sugar. Once the food is softened by the saliva and swallowed into the esophagus‚ a muscular action‚ called peristalsis‚ helps to then push the food down the esophagus and into the stomach

appendicitis. This is a 45-year-old man seen in my office on January 14 with the onset of acute abdominal pain at 10 a.m. that day. He was admitted directly to the hospital with a diagnosis of probable acute appendicitis. DIAGNOSTIC DATA: Serum amylase was normal at 64. Cultures of peritoneal fluid at the time of discharge showed no growth. CBC performed as a follow-up on January 16 showed a white count of 12‚400 (decreased from 21‚000 on January 14). Hemoglobin today is 12 (decreased from 15.5

pickles into smaller particles or boluses so that the enzymes can digest the food much easier. Lettuce contains carbohydrates‚ proteins and fat. The tongue helps turn food in the mouth and mix with the saliva in the mouth which contains salivary amylase enzyme. It then passes through the esophagus to the stomach which is a mixer and grinder of food. The stomach secrets Hydrochloric acid and enzymes that are used in the breaking down of the food. The food then leaves the stomach in form of a liquid

Name different parts of a nephron. Write absorption and secretion of different parts of a nephron. Nephron: It is the functional part of the kidney‚ encharged of filtration of blood and eliminates the nitrogenous waste of our bodies.

Abstract The aim of the experiment is to test the existence of macromolecules which are carbohydrates‚ lipids‚ nucleic acids and proteins in given samples. The first experiment is to test the existence of carbohydrates in starch suspension and potato cell. If carbohydrate is present in starch suspension‚ the solution will turn into dark blue when iodine solution is added. If carbohydrate is present in potato cell‚ starch granules can be seen clearly under microscope when iodine solution is added

polysaccharide form of this is too big for the body to simply break down directly. So‚ instead the body uses multiple forms of procedures to break down the molecule into a usable size‚ such as glucose. The body begins breaking it down with salivary amylase. This is the process of chewing it in your mouth. The disaccharides then go through intestinal digestion which break them down
