Question

nephrons, the functional unit of kidneys, are responsible for formation of urine. the sentences describe situations that are the result of problems in the urine - formation process. for the nephron shown below, match each situation to the step in the urine - formation process where the problem lies. stellas urine sample shows the presence of large proteins. johns blood test report indicates a high toxin level. miguels blood test shows an increase in metabolic waste. janices urine report shows the presence of vital minerals. reabsorption filtration secretion

Explanation:

In the urine - formation process by nephrons, filtration is the first step where large proteins should not pass through the glomerular - filtration barrier. Reabsorption is when vital minerals are taken back into the bloodstream. Secretion is for getting rid of toxins and metabolic waste. Stella's urine with large proteins indicates a problem in filtration. John's high toxin level suggests an issue in secretion. Miguel's increased metabolic waste also points to a problem in secretion. Janice's presence of vital minerals in urine shows a problem in reabsorption.

Answer:

Stella: Filtration
John: Secretion
Miguel: Secretion
Janice: Reabsorption
