The liquid that remains in the kidney after reabsorption is primarily urine, which consists of water, urea, electrolytes, and various waste products. The kidneys filter blood to remove waste and excess substances, reabsorbing essential nutrients and water back into the bloodstream. What is left, primarily in the collecting ducts, is concentrated urine, which is then excreted from the body.
What else can I help you with?
What is the material that remains after reabsorption?
The material that remains after reabsorption in the kidney is urine, which contains waste products, excess ions, and water that were not reabsorbed back into the bloodstream.
What structure is important for the reabsorption of water?
The loop of Henle in the nephron is important for the reabsorption of water in the kidney. It creates a concentration gradient in the kidney medulla, allowing for the reabsorption of water back into the bloodstream.
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.
Is it possible for the kidney to increase water reabsorption without increasing salt absorption Explain?
Yes, it is possible for the kidney to increase water reabsorption without increasing salt absorption. This can occur through the action of antidiuretic hormone (ADH), which promotes the reabsorption of water in the collecting ducts without directly affecting sodium reabsorption. In conditions such as hyperosmolarity, the kidneys can concentrate urine by reabsorbing more water, while sodium levels in the body remain stable. Thus, water reabsorption can be enhanced independently of sodium absorption.
Why are the renal plasma clearances of glucose urea and creatinine different?
Renal plasma clearances of glucose, urea, and creatinine are different due to variations in their reabsorption and secretion mechanisms in the kidney. Glucose is almost completely reabsorbed, while urea has variable reabsorption rates, and creatinine is primarily excreted without reabsorption. This difference in handling by the kidney results in different clearance values for each substance.

Why is the reabsorption of certain materials in the kidney is important to your health?
why reabsorption of certain materials in the kidneys is important for the health
The hormone that influences sodium reabsorption in the kidney is?
aldosterone
What are the three regulators of kidney function?
filtration, reabsorption and secretion
When water moves from a nephron in the kidney back to the blood it is called?
Reabsorption
In which two body organs does reabsorption of water take place?
Kidney and Colon
What is two hormones that enhance sodium reabsorbtion in the kidney?
Two hormones that enhance sodium reabsorption in the kidney are aldosterone and antidiuretic hormone (ADH). Aldosterone acts on the distal tubules and collecting ducts to increase sodium reabsorption, while ADH, also known as vasopressin, increases water reabsorption in the collecting ducts, which indirectly leads to increased sodium reabsorption.

Explain how antidiuretic hormone can help regulate hypotension Be specific?
it can help by increasing reabsorption of water by the kidney. With the reabsorption, blood plasma volume increases, thus raising blood pressure
Parathyroid hormone PTH increases what?
increases Ca++ (but not phosphate) reabsorption from the glomerular filtrate of kidney nephrons
