Refer to Figure 6.  This model shows four organs of the alimentary canal ‘stacked’ on top of each other to allow easy comparisons between these organs. For example, each of these organs shares the same types of tissue layers (labeled ‘a’ through ‘f’). But they also have major differences in their gross anatomy, such as the structures lining their lumens.  Consider these comparisons when answering the following questions. Each answer should be only 1-2 sentences or less.  1. What is the name for the shared digestive tissue layer that includes the labeled tissue f? [a] 2. What are the unique structures that are lining the lumen of organ 3? [b]
