Where does most water reabsorption occur?
Most water reabsorption in the body occurs in the proximal convoluted tubule of the kidney. This is the first part of the nephron where water is reabsorbed back into the bloodstream.
Which part of the nephron is under the control of the hormones ADH and aldosterone?
The distal tubule and collecting duct are the parts of the nephron that are under the control of the hormones ADH (antidiuretic hormone) and aldosterone. These hormones regulate water reabsorption and sodium reabsorption, respectively, in these segments of the nephron.
Where does obligatory water reabsorption occur?
Obligatory water reabsorption occurs in the proximal convoluted tubule of the nephron in the kidney. This process helps to maintain the body's water balance by reabsorbing a majority of the filtered water back into the bloodstream.
What part of the renal tubule does reabsorption occur?
Reabsorption primarily occurs in the proximal convoluted tubule of the nephron in the kidney. This is where the majority of essential substances such as water, glucose, amino acids, and ions are reabsorbed back into the bloodstream from the filtrate.
What part of nephron does adh influence?
ADH (antidiuretic hormone) acts on the collecting duct of the nephron in the kidney. It increases the permeability of the collecting duct to water, allowing the reabsorption of more water back into the body, thus concentrating the urine.
Where does most water reabsorption occur?
Most water reabsorption in the body occurs in the proximal convoluted tubule of the kidney. This is the first part of the nephron where water is reabsorbed back into the bloodstream.
What part of the renal tubule has an elaborate countercurrent mechanism for reabsorption of sodium and water?
The loop of Henle has an elaborate countercurrent mechanism for reabsorption of sodium and water in the renal tubule. This mechanism allows for the generation of a concentration gradient that helps in the concentration of urine.
What organ system is the lage intestine in?
The large intestine is part of the digestive system. Its main function is reabsorption of water from undigested food waste.
Which part of the nephron is under the control of the hormones ADH and aldosterone?
The distal tubule and collecting duct are the parts of the nephron that are under the control of the hormones ADH (antidiuretic hormone) and aldosterone. These hormones regulate water reabsorption and sodium reabsorption, respectively, in these segments of the nephron.

Obligatory water reabsorption occurs in the proximal convoluted tubule of the nephron in the kidney. This process helps to maintain the body's water balance by reabsorbing a majority of the filtered water back into the bloodstream.
What pumps sodium ions in order to reabsorb water?
The sodium-potassium pump located on the basolateral membrane of the renal tubular cells pumps sodium ions out of the cell, creating a concentration gradient that drives the reabsorption of water. This process occurs in the kidneys as part of the renal reabsorption mechanism to maintain fluid balance in the body.
What part of the renal tubule does reabsorption occur?
Reabsorption primarily occurs in the proximal convoluted tubule of the nephron in the kidney. This is where the majority of essential substances such as water, glucose, amino acids, and ions are reabsorbed back into the bloodstream from the filtrate.

ADH (antidiuretic hormone) acts on the collecting duct of the nephron in the kidney. It increases the permeability of the collecting duct to water, allowing the reabsorption of more water back into the body, thus concentrating the urine.
Which part of human body has maximum water?
The human brain has the highest water content, with approximately 75-80% of its weight being water.
Which part of the kidney is reabsorption dependent upon the body's needs at the time and regulated by hormones?
Distal convoluted tubule
Does corticosterone promote Na and water retention?
Yes, corticosterone can promote sodium and water retention in the body by acting on the kidneys to increase reabsorption of these substances. This is part of the body's stress response system to maintain fluid balance and blood pressure during times of stress.
Where does most reabsorption occur in the kidney?
The proximal tubule is the site of most reabsorption via glucose transporters (reabsorb 100% of glucose in healthy individuals), approx. 65% Sodium and various other solutes are also reabsorbed.
