In the absence of our regular face-to-face interaction in our class, please participate in a discussion with other students about what topics from this week have been most interesting or difficult. In the same discussion, please share why you thought it was interesting or why you experienced difficulties with these topics and how you have improved your understanding.
You should include any recommended study tips, review videos, or other materials you used to follow up on or help improve your understanding of the topic(s). Please respond to at least two other students in this discussion board - you can choose to respond by helping others out with suggestions for studying, you can choose to respond to students who had difficulties with the same topics as you, you can choose to respond to students who found the same topic interesting, etc.
The topic I found most interesting this week was the effect that altitude has on a person's respiratory system and how humans can adapt based on where they live. Here in Sacramento, we are anywhere between 30 and 150 feet above sea level. This means there is a lot of oxygen and our lungs don't have to work as hard. Those who live in higher elevations have a greater risk of hypoxia which is when the body has an insufficient amount of oxygen in its tissues. In order to compensate with this lack of oxygen those who are born in higher altitudes develop larger hearts and a greater lung capacity that we don't see in those who are born in a lower-altitude environment. We do not see this same adaptation in those people who move to higher altitudes in adulthood. One was that the human body can adapt for those who move to a greater elevation is by increasing the rate of respiration, heart rate, and production of red blood cells (because red blood cells carry oxygen). It is for this reason professional athletes train in higher-altitude environments. I found this video that helps to explain how the red blood cells increase at higher altitudes and stay increased for about 2 weeks after that and how it helps athletes. Also good luck to everyone this week on our first midterm.
