Wikipedia
In renal physiology, reabsorption or tubular reabsorption is the process by which the nephron removes water and solutes from the tubular fluid (pre-urine) and returns them to the circulating blood. It is called reabsorption (and not absorption) both because these substances have already been absorbed once (particularly in the intestines) and because the body is reclaiming them from a post glomerular fluid stream that is well on its way to becoming urine (that is, they will soon be lost to the urine unless they are reclaimed). Substances are reabsorbed from the tubule into the peritubular capillaries. This happens as a result of sodium transport from the lumen into the blood by the Na/KATPase in the basolateral membrane of the epithelial cells. Thus, the glomerular filtrate becomes more concentrated, which is one of the steps in forming urine. 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. However, glucose, amino acids, inorganic phosphate, and some other solutes are reabsorbed via secondary active transport through cotransport channels driven by the sodium gradient.
Renin–angiotensin system:
1. The kidneys sense low blood pressure.
2. Release renin into the blood.
3. Renin causes production of Angiotensin I.
4. Angiotensin Converting Enzyme (ACE) converts Angiotensin I to Angiotensin II.
5. Angiotensin II stimulates the release of Aldosterone, ADH, and thirst.
6. Aldosterone causes kidneys to reabsorb sodium; ADH increases the uptake of water.
7. Water follows sodium.
8. As blood volume increases, pressure also increases.
Usage examples of "reabsorption".
Hindu cycles of destruction and rebirth, and seems especially to refer to the pralaya or cosmic catastrophes which lead to the dissolution and reabsorption of our world into the Eternal.
I have to take a dozen different drugs to prevent reabsorption of calcium from my bone, collapse of my circulatory system, fluid retention, all the bad stuff micro-gravity does to unedited Earth stock.
It promotes increased reabsorption of salt in the kidney tubules, keeps potassium ions from leaving the cells to an undue extent, and maintains the proper volume of water outside the cells.
These extracts, usually called pituitrin, encouraged the reabsorption of water and therefore diminished the volume of urine.
