Hormonal Regulation of Body Fluids | ADH, RAAS & ANP Explained (Part 3)

How does the body regulate water, sodium, and blood volume? In Part 3 of our Body Fluids Physiology series, we explore the hormonal regulation of body fluids, focusing on the key systems that maintain osmolarity, volume, and blood pressure. In this lecture, you will learn: • Antidiuretic hormone (ADH): regulation, mechanism, and clinical relevance • Renin–angiotensin–aldosterone system (RAAS) • Aldosterone and sodium handling in the kidney • Atrial natriuretic peptide (ANP) and volume overload • Thirst mechanism and hypothalamic osmoreceptors • Integrated hormonal responses to dehydration and volume depletion • Clinical correlations: SIADH, heart failure, hyperaldosteronism, dehydration This video builds directly on: 👉 Part 1: Body Fluid Compartments & Electrolytes 👉 Part 2: Fluid Movement, Starling Forces & Edema 📌 This is Part 3 of a structured Body Fluids Physiology series. 👉 In Part 4, we will integrate everything clinically and discuss fluid therapy and real bedside decision-making.
