Summary
Chapter 7 References Sands JM, Blount MA and Klein JD. Regulation of Renal Urea Transport by Vasopressin. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3116377/ In this invited piece, Sands and colleagues explain that although urea is permeable across membranes, this is slow, thus urea transporters in the kidney, under control of vasopressin, are needed to facilitate transport and create the medullary gradient. Text book using 20% of extracellular compartment being in the intravascular compartment. https://courses.lumenlearning.com/ap2/chapter/body-fluids-and-fluid-compartments-no-content/ another one: https://med.libretexts.org/Bookshelves/Anatomy_and_Physiology/Book%3A_Anatomy_and_Physiology_(Boundless)/25%3A_Body_Fluids_and_Acid-Base_Balance/25.2%3A_Body_Fluids/25.2B%3A_Fluid_Compartments The chapter I wrote where I went through the math in figure 7-3.

Interrelations between serum sodium concentration, serum osmolarity and total exchangeable sodium, total exchangeable potassium and total body water. JCI 1958. This classic paper calculates the total body exchangeable sodium and potassium and establishes the relationship between these. Understanding this painstacking work helps understand the effect of supplementing potassium in the setting of hyponatremia. https://dm5mi…
