Biol 20B: Human Anatomy & Physiology Lab 12 — Gut Microbiome
Introduction In this lab, you will learn about one of my personal favorite topics, the gut microbiome. You will learn about how the bacteria in our digestive tract play a significant role in our lives.
Part I —Attending a Virtual Research Talk on the Gut Microbiome
For Part I, watch the recorded research talk below and answer the questions provided.
Your Microbiome: What Is It, and How Can It Help Or Hurt You? by Dr. Sonnenburg (Stanford Gut Micriobiome Research Center)
Questions on the Main Portion of the Talk
1. What is your gut microbiome?
2. Where in your gut do most of the microbes in more body live?
3. Can microbes in the gut influence obesity? How was this figured out?
4. Can microbes in the gut influence your mood and behavior?
5. In general, what is better for your health: having a more diverse population of microbes or a more homogenous population of microbes?
6. What is the one thing that many chronic western diseases share in common?
7. Why is eating dietary fiber important for your gut microbiome?
8. What do your gut microbes eat when there isn’t any dietary fiber present in the gut?
