This 26-minute lecture from NPTEL-NOC IITM explores the fundamental mechanisms of homeostasis in the human body. Delve into the chemical composition of intracellular and extracellular fluids and understand how solute equilibrium is maintained in cells. Learn about glucose regulation processes in the liver and pancreas, mechanisms of temperature regulation, and factors controlling arterial blood pressure. Examine the concept of variability and elasticity in physiological processes, and discover the important relationship between sleep cycles/circadian rhythms and the homeostasis of temperature and melatonin production. The lecture concludes with a Q&A session addressing key concepts about these regulatory mechanisms that maintain the body's internal stability.
