How is urine produced in the kidney tubule
Web1 Answer. The process of urine concentration in mammals occurs due to the interaction of the loop of Henle and its nearby collecting tubule. When someone is dehydrated, the kidney will aim to a maximal water reabsorption. To concentrate urine, a maximal amount of ions will be reabsorbed. This is to maximalize the concentration gradient for water. WebThe urinary system includes:-Kidneys -urinary bladder -Ureters -urethra. Kidneys Functions:-filter fluid from the bloodstream. produce urine -body's major excretory organs -rid the body of toxins, metabolic wastes, and excess ions. -regulate both the volume and chemical composition of blood -capable of gluconeogenesis during prolonged fasting …
