Detailed explanation-1: -The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes. Each nephron has a glomerulus to filter your blood and a tubule that returns needed substances to your blood and pulls out additional wastes.
Detailed explanation-2: -The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion.
Detailed explanation-3: -It contains urea, uric acid, salts, water and other waste products that are the result of various metabolic processes occurring in the body. It is formed in the primary excretory organs– the kidneys. The structural and functional unit of the kidneys is called the nephrons.
Detailed explanation-4: -Nephrons perform the primary function of the kidneys: regulating the concentration of water and other substances in the body. They filter the blood, reabsorb what the body needs, and excrete the rest as urine. The kidneys filter unwanted substances from the blood and produce urine to excrete them.
