Answer Details
In the kidney, both useful substances and wastes are removed from the blood by filtration. The renal artery carries blood to the kidney, which then enters the nephrons where the blood is filtered. The process of filtration separates useful substances like water, glucose, amino acids, and minerals from wastes such as urea, uric acid, and creatinine. The useful substances are then reabsorbed into the blood while wastes are excreted through the renal tubules into the urine. Overall, filtration is a vital process for maintaining homeostasis in the body by keeping a balance between useful substances and waste products in the blood.
