Commensal microbiota refers to the vast community of microorganisms that live on and within the human body, playing a crucial role in health and disease by aiding in digestion, synthesizing vitamins, and protecting against pathogens. This symbiotic relationship is essential for maintaining homeostasis and immune system regulation, highlighting the importance of microbial balance for overall well-being.

Digestion is the complex process by which the body breaks down food into smaller components that can be absorbed and utilized for energy, growth, and cellular repair. It involves both mechanical and chemical processes that begin in the mouth and continue through the gastrointestinal tract, ending with nutrient absorption in the intestines and waste elimination.

Homeostasis is the physiological process by which biological systems maintain stability and equilibrium in response to changing external conditions. It is essential for the survival of organisms, enabling them to regulate internal environments such as temperature, pH, and ion concentrations to ensure optimal functioning.

Homeostasis

Immune system regulation involves a complex network of cells, signals, and pathways that maintain a balance between immune activation and suppression to protect against pathogens while preventing autoimmunity. Dysregulation in this system can lead to diseases such as allergies, autoimmune disorders, and immunodeficiencies.
