The part of the colon that surrounds theanus is the:Selected Answer:anal canalThe function of salivary amylase is to beginthe digestion of:starchesThe organ of the alimentary tube that is areservoir for gradual digestion is the:stomachThe part of saliva that dissolves food fortasting is:waterThe layer of the alimentary tube that isresponsible for peristalsis is the:external muscle layerThe functions of the colon include all ofthese except:absorption of proteinsThe end products of carbohydratedigestion are:monosaccharidesThe purpose of transamination in the liver isto:synthesize the nonessential amion acidsThe plasma protein produced by the liverthat is important to help maintain bloodvolume is:albuminThe liver stores the minerals:iron and copper

Explain why villi are not necessary.Villi assist in increasing the surface area ofthe small intestine so that maximumabsorption of nutrients can take place. Theonly substances that are absorbed by thecolon are water and dissolved vitamins andminerals (including positive and negativeions). The surface area for the colon isadequate for this "minimal" absorption.
Name 1)the vitamins and minerals stored inthe liver, and 2)the substances excreted bythe liver into bile. 3)Name the fixedmacrophages of the liver, and 4) explainthe function. 5) What organ receives bilefrom the liver, what occurs to bile oncereceived by the organ, and what purposedoes bile serve?1)B12, A, D, E, K, iron, and copper. 2) Excesscholesterol and bilirubin. 3)Kupffer cells -destroy old red blood cells andphagocytize pathogens (especially bacteriaabsorbed by the colon) removing themfrom the blood before the blood returns tothe heart. 5) Gallbladder - stores andconcentrates bile until needed to aid in thedigestion (emulsification) of fats in the smallintestine.
