PASSAGE
The human gut is home to a complex ecosystem known as the microbiome, a bustling metropolis of microorganisms including bacteria, viruses, and fungi. For much of history, these resident microbes were viewed with suspicion, often associated only with disease. However, recent scientific exploration has revealed a far more symbiotic relationship. These microbial allies play a pivotal role in everything from digestion to immune defense and even mood regulation. Maintaining the health of this internal city requires a delicate equilibrium, which can be disrupted by factors like diet, stress, and antibiotics.
What is the meaning of the phrase "a bustling metropolis of microorganisms" as it is used to describe the human gut?
