What else can I help you with?
What does it mean if the clearance value of glucose in urine is zero?
it means that it has been completely reabsorbed. none secreted via urine.
Where does urine secrete from?
Urine is secreted from the kidneys into the ureters, which are tubes that transport the urine to the bladder. From the bladder, urine is expelled from the body through the urethra.
What is absorbed and secreted in the nephron?
In the nephron, water, glucose, amino acids, and some ions (such as sodium) are absorbed from the filtrate into the blood. Waste products such as urea and excess ions are secreted from the blood into the filtrate to be excreted as urine.
What hormone is secreted when blood glucose is high?
Insulin is the hormone that is secreted when blood glucose levels are high. Insulin helps to lower blood glucose levels by signaling cells to take up glucose from the bloodstream for energy or storage.
When does glucose concentration in urine become zero?
The normal glucose concentration in urine ranges from 0 to 15 mg/dL. The glucose concentration in urine becomes zero when no glucose has spilled over into the urine.
What happens to the concentration of glucose in urine as the number of glucose carriers increase?
As the number of glucose carriers increase, the concentration of glucose in the urine will decrease. This is because more glucose is being reabsorbed by the kidneys back into the bloodstream, reducing the amount of glucose that gets excreted in the urine.
What causes loss of glucose in the urine?
Insulin affects the concentration of glucose in the urine.
Why is there no glucose in urine?
All of the glucose are reabsorbed from the Proximal convoluted tubule into the surrounding capillaries,so there is no no glucose in urine.
What is the difference between glucose glycogen and glucagon?
Glucose a monosaccaride otherwise known as sugarused for energyGlycogen is secreted by the pancreas to stimulate an increase in blood sugar levelGlucagon, a hormone secreted by the pancreas, raises blood glucose levels
What blood glucose concentration what pancreatic hormone is secreted to stimulate release of stored glucose?
glucagon
Does glucose increase or decrease in sitting urine?
Glucose levels in urine typically increase after meals when blood glucose levels rise. Glucose excretion in urine is typically higher when blood glucose levels are elevated, such as in uncontrolled diabetes.
When blood glucose concentration falls what pancreatic hormone is secreted to stimulate release of stored glucose?
glucagon
