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.

Why is the proximal convoluted tubule twisted?
to increase the surface area for reabsorbtion
What organ controls pH levels?
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 help to regulate the PH of body fluids by controlling the?
The kidneys control pH by secreting or reabsorbing H+ ions.
What is the hormone ANH?
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.
What are three routes for the loss of water in the human body?
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.
What is selective reabsorbtion?
explain the process of selective reabsorbtion
What is the primary site of tubular reabsorbtion?
In the proximal convoluted tubule
Why proximal convoluted tubule is twisted?
to increase the surface area for reabsorbtion
Why is the proximal convoluted tubule twisted?
to increase the surface area for reabsorbtion
What is two hormones that enhance sodium reabsorbtion in the kidney?
cortisol and aldosterone
What step in urine formation allows the blood to retain most body nutrients?
filtration, reabsorbtion, and secretion
What step involved in urine formation allows the blood to retain most body nutrients?
filtration, reabsorbtion, and secretion
When the kidneys return salts and water to the blood it is called?
Reabsorption via a process called "secretion".
What organ controls pH levels?
Kidneys have the most significant role in regulating the blood PH level by controlling the excretion and reabsorbtion of the main acids and bases.
What is the relationship between antidiuretic hormone and the colour of urine?
As adh aids in the reabsorbtion of water in the kidneys urine becomes more concentrated so urine becomes darker.
What is the difference between filtration and reabsorbtion?
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.
The kidneys help to regulate the PH of body fluids by controlling the?
The kidneys control pH by secreting or reabsorbing H+ ions.
