A. What is/are the primary role(s) of the large intestine? a. to complete enzymatic digestion and store indigestible material b. to initiate enzymatic digestion of carbohydrates and to store water c. to absorb water from digested material, with essentially no digestive role of its own d. to secrete water into the material that is left over after all available nutrients have been absorbed e. to digest fats A. In the intestine most nutrients are absorbed regardless of whether the body has an immediate need or shortfall of them; ie there is little control over amounts taken up – which of the following does not follow this rule? a. absorption of sodium b. absorption of water c.absorption of iron d. absorption of fat soluble vitamins e. none of the above follow this rule – close control is exerted over all of them

A.
The first segment of the alimentary tract is the duodenum.
B.
Amylase hydrolyzes starches into simple sugars.
C.
Bile hydrolyzes amylase into simple sugars.
D.
Trypsin and chymotrypsin degrade lipids into free fatty acids.
E.
All of the above answer choices correctly answer the question.
Match the organ or gland with the enzyme(s) it secretes. Enzymes may be used more than once. An organ or gland may secrete more than one enzyme.(1) salivary glands (serous cells) (2) stomach (chief cells) A. peptidase B. amylase C. nuclease (3) pancreas (acinar cells) (4) small intestine D. lipase E. pepsinogen F. trypsin, chymotrypsin, carboxypeptidase G. sucrase, maltase, lactase

Stretch receptors located in the duodenum and jejunum initiate a long-lasting reflex that relaxes the internal anal sphincter several hours after food initially passes from the stomach to the intestines.B. Stretch receptors located in the rectal wall initiate the defecation reflex inresponse to an incoming mass movement.C. The defecation reflex involves contraction of the rectal wall and simultaneous relaxation of the internal anal sphincter.D. Digestive fluids secreted from the pancreas and gall bladder contain enzymesthat act on the smooth muscle of the intestine, stimulating peristalsis.E.
