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

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

Skip ahead to "Through the Peritoneal Membrane"

What is the function of a serous membrane?

1

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

What is the liver's role in digestion?

1

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).

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)

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

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"

Match the serous membrane with its location

Draggable item		Corresponding Item
pleural		abdominal cavity
pericardium		lungs
peritoneum		heart

What is the function of a serous membrane?

Which is longer: small intestine or large intestine?

small intestine

large intestine

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

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

What is the liver's role in digestion?

What is the function of the gall bladder?

digest fats

produce amylase to digest carbohydrates

store bile

absorb nutrients

Bile aids in the breakdown of:

lipids

fats

proteins

nucleic acids

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).
