1.	What is. Process ofmechanism of urine formation?
Answer» Glomerulus is a tuft of capillaries at the point of origin of each vertebrate nephron that passes a protein-free filtrate to the surrounding Bowman\'s capsule. Glomerulus is a tiny ball-shaped structure composed of capillary blood vessels actively involved in the filtration of the blood to form urine. The glomerulus is one of the key structures that make up the nephron, the functional unit of the kidney.\xa0Different steps involved in the urine formation are\xa0Glomerular filtration, Reabsorption and Secretion.\xa0Glomerular filtration\xa0is the first step in urine formation. Blood comes to the kidney via the renal artery, branches into even smaller arteries and eventually into the afferent arteriole. The afferent arteriole feeds into the glomerulus, providing the blood for the glomerular capillaries.\xa0As the blood travels through these capillaries, filtration causes a lot of the plasma contents to spill out. They spill out of the glomerular capillaries which end up within the glomerular capsule. The glomerular capsule is continuous with the rest of the renal tubules. The solution that spills out in the renal corpuscle is the solution that we will clean out to make urine.\xa0Reabsorption\xa0is the process which involves the reabsorption of valuable solutes and water back into the blood.Secretion\xa0is the third step in urine formation which helps in maintaining the acid-balance of the body.
