Selective reabsorption is the process whereby certain molecules (e.g. ions, glucose and amino acids), after being filtered out of the capillaries along with nitrogenous waste products (i.e. urea) and water in the glomerulus, are reabsorbed from the filtrate as they pass through the nephron. [1]
The electrical and concentration gradient drives more reabsorption of Na +, as well as other cations such as magnesium (Mg 2+) and calcium (Ca 2+). Cortical thick ascending limb; The cortical thick ascending limb drains urine into the distal convoluted tubule. [3] The tissue type of the loop is simple squamous epithelium.
Fig.3) Secretion and reabsorption of various substances throughout the nephron. The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion. [5]: 395–396 These apply to numerous substances. The structure and function of the epithelial cells lining the lumen change during the course of the ...
Reabsorption allows many useful solutes (primarily glucose and amino acids), salts and water that have passed through Bowman's capsule, to return to the circulation. These solutes are reabsorbed isotonically , in that the osmotic potential of the fluid leaving the proximal convoluted tubule is the same as that of the initial glomerular filtrate.
Renal glucose reabsorption is the part of kidney (renal) physiology that deals with the retrieval of filtered glucose, preventing it from disappearing from the body through the urine. If glucose is not reabsorbed by the kidney, it appears in the urine, in a condition known as glycosuria. This is associated with diabetes mellitus. [1]
In January, the state gave YSI a $7.3 million, five-year contract to run the new Broward Youth Treatment Center, a 28-bed program less than a mile away from Thompson. And this summer, YSI won contracts to take over two more state facilities, one in the Tampa area and another in Jacksonville. Read the first part of this series »

Its treatment centers are modeled after the Healing Place, also part of the network, in Louisville. “Clients work with peers in similar circumstances to motivate one another to adopt social skills and to learn core principles central to Alcoholics Anonymous and Narcotics Anonymous programs,” according to the facility’s promotional materials.
