Q.17 Describe the urine formation, filtration and re-absorption process.
Answers
Answer:
Reabsorption Moves Nutrients and Water Back into the Bloodstream. The glomerulus filters water and small solutes out of the bloodstream. The resulting filtrate contains waste, but also other substances the body needs: essential ions, glucose, amino acids, and smaller proteins.

Answer:
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. Osmoregulation is the process of maintaining homeostasis of the body. There are four basic processes in the formation of urine starting with plasma.
Filtration.
Reabsorption.
Regulated reabsorption, in which hormones control the rate of transport of sodium and water depending on systemic conditions, takes place in the distal tubule and collecting duct.
Secretion.
Excretion.
