Detailed explanation-1: -What is glomerular filtration? Glomerular filtration is the first step in making urine. It is the process that your kidneys use to filter excess fluid and waste products out of the blood into the urine collecting tubules of the kidney, so they may be eliminated from your body.

Detailed explanation-2: -The filtrate absorbed in the glomerulus flows through the renal tubule, where nutrients and water are reabsorbed into capillaries. At the same time, waste ions and hydrogen ions pass from the capillaries into the renal tubule.

Detailed explanation-3: -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-4: -The glomerulus filters the blood and removes water, glucose, salts and waste urea from it. The blood is under high pressure at the start of the nephron, which aids the filtration of the blood. These waste substances all pass from the capillaries in the glomerulus into the Bowman’s capsule. This purifies the blood.

Detailed explanation-5: -The filtrate flows from the proximal tubule and into the Loop of Henle. The loop of Henle concentrates the filtrate, by removing more water from it, and passes it to the distal tubule. From the distal tubule it travels to the collecting duct-now called urine.
