Question
Which substance is lost from the body of a healthy person by the kidneys, but not by the lungs? Question 16Select one:A.glucoseB.ureaC.waterD.carbon dioxide
Solution
The substance that is lost from the body of a healthy person by the kidneys, but not by the lungs, is urea.
Here's why:
A. Glucose - This is not typically excreted by the kidneys in a healthy person. The body uses glucose for energy, and any excess is stored.
B. Urea - This is the correct answer. Urea is a waste product that is produced in the liver, transported in the blood to the kidneys, and excreted in the urine. It is not excreted by the lungs.
C. Water - Both the kidneys and lungs play a role in the excretion of water. The kidneys excrete water as a component of urine, and the lungs excrete water vapor during exhalation.
D. Carbon dioxide - This is excreted by the lungs during exhalation. It is not excreted by the kidneys.
So, the correct answer is B. Urea.
