Why is insulin useful in determining glomerular filtration rate?
Insulin is useful in determining glomerular filtration rate (GFR) because it is a substance that is freely filtered at the glomerulus and is not secreted or reabsorbed by the renal tubules. When insulin is administered intravenously, its clearance from the blood can be measured to estimate GFR accurately. This method provides a reliable assessment of kidney function, as changes in insulin clearance reflect alterations in glomerular filtration capacity. Additionally, insulin clearance is less affected by factors such as dietary intake and hydration status compared to other endogenous markers.
What is the resulting substance after filtration?
After filtration, the resulting substance is the filtrate, which is the liquid or solution that has passed through the filter, leaving behind any solid particles or impurities. The filtrate is usually collected in a separate container from the residue that is left on the filter.
Why is it important to distinguish between measures of quantity and concentration in renal function?
Distinguishing between measures of quantity (such as glomerular filtration rate) and concentration (such as plasma creatinine) in renal function is crucial because quantity measures the actual amount of substance filtered by the kidneys, while concentration reflects how much of that substance is present in the blood. Quantity helps determine the overall function of the kidneys, while concentration may be influenced by factors beyond renal function, such as hydration status or muscle mass. Evaluating both measures provides a more comprehensive assessment of renal function.
How do you separate two invisible substance?
BY THE PROCESS OF FILTRATION (by paper folding)
Why does substance remain in the funnel during filtration?
Substance may remain in the funnel during filtration due to clogging of the filter paper by fine particles, improper wetting of the filter paper before filtration, or insufficient pressure to facilitate the filtration process. Additionally, some substances may have a tendency to stick to the filter paper or be insoluble in the solvent being used for filtration, leading to retention in the funnel.
What refers to how plasma is cleared by the kidneys of a particular substance?
Clearance rate. There are formulas for rates such as creatinine clearance. Also, you may be thinking of GFR, or glomerular filtration rate.

What is GFR lab test for?
GFR on a blood test stands for Glomerular Filtration Rate. This test is used to used to test how well the kidneys are working. It estimates how much blood passes through the filters in the kidney, called the glomeruli, every minute.The normal value for GFR is 130-140 ml /min of creatinine(a substance used to check kidney functioning)glomerular filteration rate, this test is done to check the kidney function.GFR stands for glomerular flow rate. It provides an index for the function of the kidneys.
What is the substance called that is insoluble after filtration?
residue

What is ultra filtration?
The filtration of a colloidal substance through a semipermeable medium that allows only the passage of small molecules.
What is the resulting substance after filtration?
After filtration, the resulting substance is the filtrate, which is the liquid or solution that has passed through the filter, leaving behind any solid particles or impurities. The filtrate is usually collected in a separate container from the residue that is left on the filter.

What is the definition of residue in science?
In science, residue refers to the portion of a substance that remains after a process has been completed. It can be in the form of solids, liquids, or gases that are left behind as a result of a chemical reaction, filtration, or separation process. Residues are often analyzed to understand the composition of the original substance or to determine the effectiveness of a process.
What type of substance can be separated by filtration?
Substances that consist of a solid suspended in a liquid can typically be separated using filtration. The solid particles are trapped by the filter, while the liquid passes through, resulting in separation.
