Answer :
1. Stella's urine contains protein, which is a sign of poor filtration or insufficient absorption. The protein is left in the filtrate and excreted in urine because there is less reabsorption at the proximal tubule.
2. The high level of toxins found in Johns' blood test suggests that the kidneys are not properly secreting toxins out of the body. As a result, the amount of toxin in the blood rises due to decreased elimination.
3. The kidneys are used to remove metabolic waste from the body. The insufficient reabsorption will be the cause of the metabolic waste. Miguel's blood levels of waste may have increased because his kidneys either failed to filter waste properly or the waste was reabsorbed.
4. Following filtration, the majority of the body's valuable substances are reabsorbed. This enables the body to retain minerals. Vital minerals may be released into Janice's urine as a result of insufficient reabsorption.
What percentage of the kidneys are nephrons?
The total number of nephrons (glomeruli) in healthy human kidneys has been shown to vary significantly in several studies. The average number of nephrons per kidney, according to studies, is between 900,000 and one million, but the number of nephrons in a single kidney can range from 200,000 to more than 2.5 million.
