How It Works The program will display a question at the top of each screen. Click on the button with the correct answer At the end of the quiz, it will show you how many right and wrong answers you chose. Click here to begin the game Help! Nothing happened!

Troubleshooting If you weren’t able to begin the game, it’s probably because your PowerPoint security settings are set too high. Here’s what to do: –Open PowerPoint and choose ‘Options’ from the ‘Tools’ menu –Click on the ‘Security’ tab and on ‘Macro Security’ in the lower half of the screen. –Set Macro security at ‘Medium’ and close PowerPoint. Click the button below to go back to the Main Menu, and re-open this quiz. The computer should ask you whether you want to enable macros. Tell it to enable them.

Cephalic Intestinal Gastric Cephalic Pancreatic Gastric Pancreatic Intestinal Cephalic Intestinal Pancreatic Intestinal Gastric Cephalic Gastric Intestinal The three stages of digestion, in correct order, are:

Which part of the autonomic nervous system is activated during digestion? Peripheral Parasympathetic CentralMucosal Unsympathetic Sympathetic

During digestion, smooth muscle activity in the gut: Stops Increases DecreasesDoes not change Decreases and then increase Increases and then decreases

Carbohydrates are digested by the enzyme: Amylin Pepsin CarboxypeptidaseGlucagon Amylase Lipase

Carbohydrate molecules are broken down into: Saccharin Polysaccharides Polypeptides Monosaccharides and disaccharides Glycogen Glycerol

When they have been absorbed into the blood, monosaccharides: Are picked up by cells using glucose porter proteins Are released into the urine Leave the body in the sweat Stimulate glucagon secretion Are destroyed by the liver Leave the body in the stools

To make the glucose porter proteins, cells need: Glucagon Pepsin AmylinGlycogen Amylase Insulin

Without insulin, the digested sugars: Accumulate in the blood Pass out in the stools Are made into proteins Are converted back into carbohydrates Go out in the sweat Enter fat cells

If Insulin is present, excess sugar is: Picked up by cells and stored as starch picked up by the cells and stored as glycogen Returned to the intestinal contents Released into the stools Released in the urine Picked up by the cells and stored as glucagon

When the blood glucose is low, the pancreas secretes: Insulin AmylaseSecretin Amylin Glucagon Glycogen

Glucagon causes the cells to: Secrete digestive enzymes Stop all metabolic activityMake more glycogen Pick up food from the blood Break down their stored food and release it to the blood Build muscle

During the gastric phase, the stomach: Secretes trypsin and pancreatic amylase Turns off the parasympathetic nervous system secretes HCl, mucus, pepsinogen, intrinsic factor, and gastrin Closes the lower esophageal sphincter Opens the pyloric sphincter Inhibits intestinal motility

What is Gastrin? A ligament holding the stomach in position A soapy substance lining the alveoli A substance in the sweat that causes body odor A hormone that stimulates stomach activity A neurotransmitter that tells your brain your stomach is full A digestive enzyme that sometimes causes ulcers

What makes the stomach stop creating Gastrin? Decreased blood volume Hormones released from fat cells Hormones released by the intestines when food enters them The parasympathetic nervous system Stretch receptors in the stomach wall Shrunken cells

The pyloric sphincter lets food through when: The duodenum is empty The cephalic phase of digestion begins Insulin is released The parasympathetic system turns on The stomach squeezes small particles down through it The stomach has stopped secreting digestive enzymes

The duodenum releases three hormones. What are they? Cortisol, aldosterone, and testosterone Gastrin, secretin, and ghrelin Secretin, cholecystokinin, and glucagon Insulin, glucagon, and amylin Secretin, Cholecystokinin, and GIP Antidiuretic hormone, Parathyroid hormone, and Growth hormone

One effect of cholecystokinin is: Decreases intestinal motility Increases blood K+Causes hunger Nothing causes the gall bladder to send bile into the duodenum Causes insulin secretion

What does the pancreas do in response to cholecystokinin? Releases insulin Releases thyroxine Sends acid to the duodenum Sends bicarbonate to the duodenum Sends digestive enzymes to the duodenum Releases glucagon

What is bile? An antacid that protects the duodenum A compound made from bilirubin and cholesterol, used to emulsify fats A toxic compound caused by white blood cell breakdown A neurotransmitter that turns off stomach motility A hormone that tells the brain the man has eaten fats A digestive enzyme that breaks down fat molecules

Where is bile made? The liver The bone marrowThe thymus The gall bladder The stomach The spleen

A man with liver failure might develop: High blood osmolarity Sunken eyes Low body temperatureFatty stools Constipation Acne

The food absorbed from your gut contents goes straight to the: Hepatic portal vein Heart StoolsBrain Fat cells Urine
