Demo VIII: Respiratory Changes in PregnancyOne way to help illuminate respiratory physiology is a discussion of how breathing changes during pregnancy, the topic of the animation in this module. The pictures on the screen act as a visual aid for students trying to grasp the normal physiology of breathing in pregnant women. Dr. Michael Parker explains that the diagram also hits on the actual mechanics of breathing, respiratory patterns, and how hormones affect breathing in pregnant women. On the screen, students see two women, a non-pregnant woman on the left and a pregnant woman on the right. Both women have an accompanying schematic that represents their lung volume. The animation shows each woman taking breaths in and out, so students get a sense for how the rib cage moves. A quick visual comparison also reveals that the angle formed by the lower part of the rib cage is different between the two women-this is one of the changes that occurs during pregnancy that allows a woman to maintain a higher volume of air as she breathes in and out. To further highlight the mechanisms that cause these changes, there is a "Show Me" button in the lower left-hand corner that students can click on. This starts a narration that walks through more detailed explanations of respiratory physiology during pregnancy, including discussion of the hormone progesterone, which softens certain cartilages in women, accounting for changes in the rib cage angle. Key Lesson: In this animated diagram, students can study the divergent breathing patterns of pregnant and non-pregnant women while listening to supplementary narration about the effect of hormones on the body's physiology. |
