- How Do Tibetans Survive at High Altitudes?
- If you live in the lowlands, you may have experienced the huffing and puffing that typically accompany a trip to higher altitudes. That's because oxygen levels go down as one goes up. Travelling to Denver from sea level means a 17% decrease in available oxygen. Our bodies compensate for even this small change with faster breathing and a higher heart rate — at least until we acclimate to the thinner atmosphere.
- Modeling the Alimentary Canal with String
- The entire length of the adult GI tract from mouth to anus is approximately 9-10 meters in length. In this activity we will be measuring out the length of the gastrointestinal (GI) tract in a scaled version to compare the lengths of each section. The scale model represents approximations of the length of each section of the GI tract.
