What happens if the reabsorption of sodium by the renal tubule is inhibited?

reabsorption of water by renal tubule decreases

∙ 13y ago
If the reabsorption of sodium by the renal tubule is inhibited, it can lead to increased sodium excretion in the urine, which can result in higher urine output (diuresis). This can lead to loss of water and electrolytes, potentially causing dehydration, electrolyte imbalances, and alterations in blood pressure.

What types of transport are utilized during glucose reabsorption and where do they occur?
Glucose reabsorption in the kidney primarily involves secondary active transport, specifically sodium-glucose cotransporters (SGLTs) located in the proximal convoluted tubule of the nephron. SGLT1 is responsible for glucose and sodium reabsorption in the early proximal tubule, while SGLT2 reabsorbs glucose in the late proximal tubule. Transporters like GLUT2 are also involved in moving glucose out of the tubule cells and into the bloodstream.
Aldosterone acts on what part of the kidney?
Aldosterone acts on the distal convoluted tubule and collecting duct in the kidney to increase sodium reabsorption and potassium secretion.
Name the process by which molecules move from the proximal convoluted tubule into the blood?
Reabsorption is the process by which molecules move from the proximal convoluted tubule into the blood.
What is the effect of ANP in the distal tubule?
Atrial natriuretic peptide (ANP) acts on the distal tubule of the kidney to inhibit sodium reabsorption and increase sodium excretion. This leads to increased urine production and ultimately helps regulate blood pressure and fluid balance in the body.
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.
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.
Aldosterone acts on what part of the kidney?
Aldosterone acts on the distal convoluted tubule and collecting duct in the kidney to increase sodium reabsorption and potassium secretion.
Where does reabsorption primarily occur in the urinary system?
Reabsorption primarily occurs in the renal tubules of the kidneys. As the filtrate passes through the tubules, essential substances like water, glucose, and ions are reabsorbed back into the bloodstream to maintain the body's balance of fluids and electrolytes.
Where does sodium get reabsorbed?
Sodium is primarily reabsorbed in the kidneys, specifically in the proximal tubule and the thick ascending loop of Henle. Around 67-70% of sodium reabsorption occurs in the proximal tubule, while the remaining 25-30% occurs in the thick ascending loop of Henle.
Name the process by which molecules move from the proximal convoluted tubule into the blood?
Reabsorption is the process by which molecules move from the proximal convoluted tubule into the blood.
Mechanisms of tubular reabsorption include what?
Reabsorption of nutrients in the renal tubule occurs via active transport and facilitated diffusion. Amino acids, glucose and phosphates are reabsorbed at the proximal convoluted tubule via active transport. Water and sodium chloride is reabsorbed at the loop of henle via facilitated diffusion.
Where does glucose reabsorption occur in the nephron?
Glucose reabsorption takes place in the proximal renal tubule. This tubule is a portion of the nephron that contains fluid. The functions of the nephron include the reabsorption and secretion of various substances like ions, glucose, and amino acids.
Where does selective reabsorption takes place?
The proximal convoluted tubule
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.
Reabsorption of filtered glucose from the lumen in the PCT is largely by means of?
Reabsorption of filtered glucose from the lumen in the proximal convoluted tubule (PCT) is largely by means of the sodium-glucose cotransporter 2 (SGLT2). This transporter is responsible for actively transporting glucose and sodium from the renal tubule back into the bloodstream. The glucose is then further passively reabsorbed through the facilitative glucose transporter 1 (GLUT1) in the PCT cells.
What is the primary site of tubular reabsorption in the kidneys?
The distal convoluted tubule or the collecting tube.
What hormone regulates sodium re absorption in the distal convoluted tubule?
Aldosterone is the hormone that regulates sodium reabsorption in the distal convoluted tubule of the nephron. It acts on the epithelial cells of the tubule to increase the reabsorption of sodium and water, helping to maintain electrolyte balance and blood pressure in the body.
