What is the Origin of Biological Ecosystem?

This term is a direct application of the ecological concept of an 'ecosystem'—a community of living organisms interacting with their non-living environment—to the internal human environment. Its clinical relevance has surged with the extensive research into the gut-brain-endocrine axis, highlighting the microbiota's role as a virtual endocrine organ.

What is the Mechanism of Biological Ecosystem?

The gut microbiota, a central part of this ecosystem, ferments dietary fibers to produce short-chain fatty acids (SCFAs), which are critical signaling molecules impacting satiety hormones and immune cell function. Furthermore, the microbiome modulates the enterohepatic circulation of estrogens, directly influencing systemic hormone levels and metabolism. Disruption of this delicate ecosystem, known as dysbiosis, can lead to chronic inflammation and subsequent hormonal imbalance, underscoring its regulatory power.

Biological Ecosystem

Meaning

The Biological Ecosystem refers to the integrated, dynamic network of all living components within the human body, encompassing the host cells, the vast microbiome (gut, skin, oral), and their collective metabolic byproducts and signaling molecules. This complex internal environment functions as a unified system, where the health and diversity of the microbial populations exert profound regulatory influence on host physiology, including immune function and the endocrine system. Maintaining the integrity and balance of this ecosystem is paramount for systemic health and resilience.
