There is at least one question on almost every slide in the virtual pig dissection. Scroll down and click next to move on to the next slide.

1

Sensory papillae are more commonly called and are found on the . (choose 2)

1

ID the structure

hard palate

soft palate

tongue

1

What enzyme is active in this area...and what does it break down?

1

What is the funtion of the flap in question 3?

to propel food down the esophagus

to cover the trachea so food doesnt go down

to grind food before swallowing

Skip ahead to "Through the Peritoneal Membrane"

1

Match the serous membrane with its location

Draggable item		Corresponding Item
pleural		abdominal cavity
pericardium		lungs
peritoneum		heart

1

What is the function of a serous membrane?

1

ID the structure:

small intestine

large intestine

stomach

1

Which is longer: small intestine or large intestine?

small intestine

large intestine

1

Why is the small intestine this long?

it takes time to digest food and absorb nutrients

its quicker to prepare undigested material and make feces

2

Most food stuffs are absorbed in the small intestine, but what IS absorbed in the large intestine?

1

ID the structure:

liver

stomach

gall bladder

1

What is the liver's role in digestion?

1

What is the function of the gall bladder?

digest fats

produce amylase to digest carbohydrates

store bile

absorb nutrients

1

Bile aids in the breakdown of:

lipids

fats

proteins

nucleic acids

Since fats and water dont mix, bile emulsifies the fat into microscopic droplets to aid in their digestion.

As you can see from this picture, bile can be released from the liver directly into the small intestine via the hepatic duct into the common bile duct. If bile is not needed at the time, it can divert into the gall bladder via the cystic duct (a sphincter prevents it from going into the duodenum).

1

Draggable item		Corresponding Item
sphincter of oddi		empties into the duodenum
pancreatic duct		leads out of the liver
common bile duct		leads out of the gall bladder
cystic duct		leads out of the pancreas
pancreas		secreted by the liver
hepatic duct		stores bile
bile		closes off end portion of common bile duct and pancreatic duct
gall bladder		produces insulin

1

Place a small circle on the picture where you think the pyloric sphincter is:

1

The folds in the stomach as pictured above, are called:

1

In the image above, which number is the pancreas?

1

2

3

4

1

Where pepsin is active:

1

2

3

4

1

Where trypsin is active:

1

2

3

4

The pancreas produces a number of enzymes that aid in digestion. These enzymes may flow into the small intestine via the common bile duct (exocrine), or they may enter the bloodstream (endocrine)

1

What are two endocrine hormones are produced in the pancreas?

1

What letter on the image above is the mesentery?

A

B

C

1

What structures are prominent in the mesentery?

blood vessels

smooth muscle

sphincters

glands
