There are three stages involved in the process of urine formation. They are- Show
2. Selective reabsorption 3. Tubular secretion Glomerular filtration
Therefore: 55-(30 +15) = 10mmHg.
Selective reabsorption
Tubular secretion
Composition of human urine Water – 96% Urea – 2% Uric acids, creatinine, pigments- 0.3% Inorganic salts – 2% Bad smell is due to Urinoid Pale yellow color due to urochrome or urobillin (which is a breakdown product of haemoglobin) Micturation:

Physiology of Urine formation
During which steps of urine formation are substances removed from the blood?Tubular Secretion
Secretion usually removes substances from the blood that are too large to be filtered (ex: antibiotics, toxins) or those that are in excess in the blood (ex: H+, K+). These substances secreted into the tubule are destined to leave the body as components of urine.
What are the 3 steps of urine formation clear response?Urine is formed in three main steps- glomerular filtration, reabsorption and secretion.
How does blood become filtered to produce urine?Blood flows into your kidney through the renal artery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.
What two ways are substances removed from blood and added to urine?What are the two ways substances are removed from the blood and added to the forming urine? *Substances are removed from the blood during glomerular filtration and tubular secretion. While glucose is filtered out at the glomerulus, none is excreted in the urine.
