In this course, we teach you the basic physiology of sodium homeostasis in the human body. We begin by explaining the important concept of body fluid compartments and the factors controlling the distribution of water between these compartments. We explain the meaning of the terms plasma osmolarity and plasma osmolality and explain how they are related. We teach you how plasma osmolarity is regulated by ADH, thirst mechanisms and the renin-angiotensin-aldosterone system.
