Glomerulus

clearance. GFR is the volume of filtrate formed per unit time. By comparing the clearance of creatinine to GFR, it was able to determine whether there was any reabsorption or secretion of creatinine by the kidney. If a substance is filtered at the glomerulus and fully, completely reabsorbed and not secreted, the clearance will be zero. If a substance is filtered and unmodified by the nephron, clearance will equal GFR. Clearance will be greater than GFR when a substance is filtered and secreted,…

Functions of the Kidneys The kidneys assist in the internal regulation of the body by performing the following function- * Filtration - The kidneys remove the end products of metabolism and substances that have accumulated in the blood in undesirable amounts during the filtration process. Substances removed from the blood include urea, creatinine, uric acid and urates. Undesirable amounts of chloride, potassium, sodium, and hydrogen ions are also filtered from the blood. The glomerular…
