Potassium Balance Regulation,tration of plasma K. affects the renal capacity to concentrate urine; this effect is directly related to a loss of connecting and principal cells?capacity to respond to AVP. The result is a marked polyuria, which is reversed when the extracellular and intracellular concentration of K. is reestablished.

Functional Anatomy of the Kidney, renal papilla. Each of the papillae drains urine into the pelvic space. The kidneys of smaller mammals, such as rodents, rabbits, and others, are unipapillar, and all urine passes through a single papilla into the pelvic space.

Functional Anatomy of the Kidney, structure of the kidney can be seen in Fig. 2.1. Each kidney is wrapped by the renal capsule. The renal parenchyma consists of a surface area or cortex and a deeper area or medulla. The shape of the medulla resembles a pyramid, where the apex is oriented towards the pelvic space and the base toward

Transport of NaCl, Organic Solutes, and Water in the Renal Tubule,ormal blood glucose levels, glucose is reabsorbed to 100%. Water is also reabsorbed above 99%. Solutes like urea are only reabsorbed nearly 60%, while 93% of the filtered potassium load is reabsorbed. The lesson from this table is that under normal circumstances, the kidneys handle each molecule ind

Regulation of the Effective Circulating Volume and the Sodium Balance,ma osmolality and water balance, the kidney indirectly regulates cell volume. By regulating the circulating volume and sodium balance, the kidney maintains the fluid volume in the arterial vascular compartment and, indirectly, the fluid volume in the interstitial compartment constant. This function

Renal Regulation of Acid-Base Balance, wider (6.80–7.80; 160–16?nM, respectively). Normal arterial plasma pH is 7.40, equivalent to a H. concentration of 40?nM, which is one million times less than the concentrations of other cations in the plasma, such as Na., K., and Ca. all in the millimolar range. The H. has a very small hydrated mo
