Digestive System Part 1

Today's Medical Topic:  Digestive System Part I - If you aren't in my A&P II class you probably won't understand this.

What Are We Looking For:   The difference between the two liver models on our practical exam.

Here is one of the "livers" on our practical.  This one has more parts than the other ones so if you are asking yourself "Which one is more complicated?"  It is this one.  This is the only one that has a right and left hepatic duct.

To remember it correctly place the model of the liver in anatomical position and then rotate it up to see the vessels and what not.  The common hepatic duct on this model is a little confusing so let's clarify.

That little whitish part is actually the common hepatic duct on this model.  It is just a matter of how far up the cut is made.

Lets take a look at the other less complicated model:

You should position and rotate this one the same way and you can see how this one is different.  So basically if it has numbers you can see on it it is the less complicated model.  163 is the cystic duct, 162 is the common hepatic duct, and 165 is the bile duct.

So thats is all I got for tonight.  Enjoy.
