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) because these substances have already been absorbed once (particularly in the intestines) and the body is reclaiming them from a postglomerular fluid stream that is on its way to becoming urine (that is, they will soon be lost to the urine unless they are reabsorbed from the tubule into the peritubular capillaries.

It is when the body absorbs particles back into the body.
what is the reabsorption process ?
to increase the surface area for reabsorbtion
Kidneys have the most significant role in regulating the blood PH level by controlling the excretion and reabsorbtion of the main acids and bases.
The kidneys control pH by secreting or reabsorbing H+ ions.
ANH stands for atrial natriuretic hormone. It is released by the atria when to much pressure is bing applied to them (Blood pressure is to high). The hormone inhibits water reabsorbtion in the kidneys, thereby reducing blood volume and lowering blood pressure.
Breatheing, sweating, extraction by the kidneys to make urine, and loss through the large bowel because of inefficient water reabsorbtion. Tears,mucous secretions from the nose and elsewhere are insignificant sources as is spitting.

Reabsorption via a process called "secretion".

As adh aids in the reabsorbtion of water in the kidneys urine becomes more concentrated so urine becomes darker.
Filtration Filtration is accomplished by the movement of fluids from the blood into the bowmans capsule. = Reabsorption = = Reabsorption involves the selective transfer of essential solutes and = water back into the blood.
