If the process of urine formation is disrupted or inhibited, over an extended period of time, toxins begin to accumulate in the body and this can cause quite serious medical conditions and eventually results in death.
Basically, the process of urine formation takes place in three (3) stages, as blood plasma flows through the nephrons.
After water and other substances leave the surface of the renal tubule, they are reabsorbed by the capillaries, into the bloodstream.
Tubular secretion is the process in which renal tubule extracts chemicals from the capillary's blood and secretes them into the tubular fluid.
Fluids comprising excess water, salt and metabolic waste products are extracted from the blood as it enters the Glomerular filtration is a process in which water and some other substances in the blood plasma pass from the capillaries of the glomerulus into the Bowman's capsule.
The kidneys are not only responsible for eliminating metabolic wastes from the body but they also prevent excessive water loss, in doing so.
Urine formation is a very sophisticated process that takes place in the kidneys.
This important process provides a mechanism for the body to get rid of metabolic wastes and toxins, which can be deadly if allowed to accumulate in the body.
It allows them to maintain a relatively stable glomerular filtration rate in spite of changes in arterial blood pressure.
The second stage of urine formation is tubular reabsorption and secretion.
