Organs 9: Lungs
In this layer, we will take a close look at the lungs and pancreas.
  • The lungs are difficult to locate in a preserved frog.
  • They're at the anterior end of the body cavity on either side of the heart.
  • In the pithed frog, they are much easier to locate. (Only one lung expands because the other one was punctured.)
  • Move your pointer over each picture to see the lungs highlighted.
