GENERAL HISTOLOGY

Detailed explanation-1: -Urine is formed in three main steps-glomerular filtration, reabsorption and secretion. It comprises 95 % water and 5% wastes such as ions of sodium, potassium and calcium, and nitrogenous wastes such as creatinine, urea and ammonia.

Detailed explanation-2: -There are 3 main steps of urine formation: Glomerular filtration, Reabsorption Secretion. These processes ensure that only waste and excess water are removed from the body.

Detailed explanation-3: -Urine formation occurs in three main stages in the kidney. The first is filtering things out of the blood and into the filtrate. The next is reabsorbing the important stuff from the filtrate. Finally, anything that needs to be shipped right out of the body is secreted out.

Detailed explanation-4: -Water Filtration and Reabsorption in the Nephron In the glomerulus, water is initially filtered out, along with the other solutes e.g. Na+, K+ and glucose. From here H2O needs to be reabsorbed into the tubule cells and then back into the interstitial space.

Detailed explanation-5: -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.
