Human Variation
High altitudes disrupts homeostasis in that it can limit a person's’ ability to accomplish easy tasks, such as walking or climbing, can cause dehydration, and can cause hardships in breathing. This is due to the fact that in higher altitudes, the atmosphere is less dense, therefore the molecules are farther apart, making it more difficult to breath. In higher atmospheres as well, our heart has to do twice the work in order to get oxygen into our lungs, which can be a lot of stress for some people and make them feel fatigued. 1. Short Term A short-term adaptation would be when our heart pumps harder in order to get oxygen into our lungs. Image #1 Facultative A facultative adaptation would be “the increase of oxygen carrying blood cells.” This is an adaptation that occurs genetically and this trait will continue as long as someone needs it when living in high altitude habitats. Developmental: One way humans have adapted to high altitude would be by “dev...
