Urinary System

Question 10 - Single Best Answer

Mrs. Nephro is a 29 year old black female who you have followed for a long time. She was born with abnormal kidneys. You remember her very first visit to your office: she presented at the age of 5 for her Kindergarten check-up and her urine lab studies were abnormal. She had 4.0 grams of protein in her urine, aka proteinuria (any value > 3.0 defines proteinuria). From which site/structure is she losing the protein?

E) distal convoluted tubule

Sorry...
This structure, like the collecting duct, absorbs water when needed. It is under the influence of anti-diuretic hormone (aka ADH).
