Refer to Figure 2.  The model labeled A shows the lungs within the thoracic cavity. As you can see, this cavity is a tightly packed space with multiple blood vessels, airways, and the beginning of the digestive tract. Additionally, the lungs need to expand and contract without relying on dense fibrous connective tissue  or smooth muscle pulling on them.  Answer the following questions about the organs located in this space and the structures that impact their function. Each answer should be only 1-2 sentences or less.  1. The right lung has a larger volume but is often described as ‘shorter’; what makes the right lung shorter than the left? 2. Acid reflux is also called ‘heart burn’; why would indigestion feel like pain in the heart? 3. Fluid between two membranes helps expand and contract the lungs; what is the name of the membrane closest to the surface of the lungs?

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? 2. What are the unique structures that are lining the lumen of organ 3?
