Search Menu. Instructions: Internal anatomy Scroll down to read all the instructions. Close the Instructions to begin activity. Start with the fat bodies. Locate the liver the large, dark three-lobed organ and the smaller gall bladder that lies beneath it. Locate the esophagus. Locate the stomach -the largest of the digestive organs. Locate the small and large intestines.

Locate the small pancreas. Locate the dark red spleen, also in the tissues of the mesentery. Locate the two small dark pink lungs, which are on either side of the heart. Locate the heart, usually near the top of the liver. Here, you can clearly see the pylorus, where the stomach ends and the small intestines begin. Food is moved down the esophagus by a process called peristalsis, which is coordinated muscular contraction of muscles in the esophagus.

The glottis can prevent foreign objects from entering the lungs. Nares These small slits are called external nares and allow a frog to float on the surface of the water and still inhale oxygen. Eustachian openingsThese small holes are the openings to the tympanum and are allow for equalization of pressure on either side of the tympanum.

Topics include Biology, organ systems, and ecological systems. Virtual classroom programs are designed for up to 40 student participants on zoom. A minimum of 2 weeks' advance notice is required for all registration requests. If you have questions, please contact us at Thus a major part of the game is making sure you leave the organs that will obscure other ones until last.

For example, choosing the skeleton or liver first is not a good idea. If you get stuck you have several options.

You can delete some of the currently visible organs if you think they are obscuring the one you have currently selected. To delete an organ that you have already placed, just uncheck its checkbox. Alternatively, you can click on the arrows control at the top of the frog to change the angle on the frog in the same way as in the dissection kit.
