How is the amount of urine produced regulated?
Answers
The amount of urine largely depends on the amount of excess water or water reabsorbed and also dissolved wastes present in the body. When excess water in the body is more, large quantities of dilute urine is excreted out. On the other hand if the excess water is less, a small quantity of concentrated urine is excreted. When there is more quantity of dissolved wastes in the body, more quantity of water is required to excrete them. As a result of which, the urine produced increases. The amount of urine produced also depends on some other factors like: (a) Habitat of an organism (b) Anti-diuretic hormone (ADH).
Answer:
Urine volume and attentiveness is regulated through the same procedures that adjust blood volume. Antidiuretic hormone (ADH) — formed by the posterior pituitary gland — increases the quantity of water reabsorbed in the distal complicated tubule and collecting duct.
The hypothalamus panels the mechanisms of ADH secretion, either by adaptable blood volume or the concentration of water in the blood. Water interchanges out of the kidney tubules through the aquaporins, falling urine volume.
