HUMAN ANATOMY/PHYSIOLOGY II
* Note that these images probably do not cover all the objects you will study in your
lab, and some of these may be omitted by your lab instructor for test purposes. Your
lab instructor will indicate which of these lab objects you are responsible for learning.

HOW TO PRINT THIS PDF FILE FROM THE WEB
It is best to study these slides on the web (fast connection), but if you want to print
them, follow these steps:
Click on File.
Click on Print.
Click on Pages per sheet (4 per sheet is recommended).
Click on Properties at the top of the page.
Click on Color. If you are printing from a computer at VSCC, you should choose Print in grayscale and
Black print cartridge only. Using your home computer and printer, you can choose color print if you wish.
Then click on OK a couple of times.
Lung cross-section showing alveoli; the wall of an
alveolus consists of simple squamous epithelium and
cuboidal epithelium
Lung c. s. showing a much magnified alveolus; note the squamous epithelial
Cells (type 1 cells) and the cuboidal epithelial cells (type 2); the type 2 cells
secrete surfactant which prevents the collapse of the alveoli after exhalation.

Spleen
Know the structures of the pancreas:
Know the parts of the small intestinal wall.
Know that the villus contains a lacteal (tiny lymphatic vessel for absorption
of the products of fat digestion) and blood capillaries for absorbing glucose
and amino acids:
Know that the liver contains compartments called lobules and that there
typically is a central vein within each lobule.
