This worksheet is a supplement to the frog dissection activity where students examine a preserved specimen. The main structures of the abdominal cavity are shown on this image and students practice identifying them using the included word bank. ( The worksheet could be modified to not include it should students need a greater challenge. )
I usually do this practice the day after students have dissected the frog to help them conceptualize how the structures fit together. Beginning anatomy students often make the mistake of trying to memorize drawings or photos rather than attempt to make a mental diagram of how the parts fit together. We trace the path of food from the esophagus to the stomach, duodenum, ileum, and finally the large intestine (cloaca). I also show them a photo album of frogs we have looked at over the years and help them to compare the photos of the frogs to diagrams of their anatomy.
