Here is the list of structures you should be able to identify: 
Tongue 
Salivary Glands 
Pharynx 
Papillae (taste buds) 
Soft palate / Hard palate 
Esophagus 
Liver 
Small Intestine
 Duodenum 
Ileum (Jejunum)
 Large Intestine (colon)
 Cecum
 Gall bladder / Bile duct
 Pancreas
 Pyloric Sphincter

 Anus 

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

1

What is the funtion of the flap in question 3?

Skip ahead to "Through the Peritoneal Membrane"

1

Match the serous membrane with its location

Draggable item		Corresponding Item
pericardium		abdominal cavity
peritoneum		lungs
pleural		heart

1

What is the function of a serous membrane?

1

Identify the structure (its the thin membrane attached to the small intestine)

1

Which is longer: small intestine or large intestine?

1

Why is the small intestine this long?

2

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

1

ID the structure:

1

What is the liver's role in digestion?

1

What is the function of the gall bladder?

1

Bile aids in the breakdown of:

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

Where pepsin is active:

1

Where trypsin is active:

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?
