If GFR is 125 ml/min, and you are studying a drug that has a renal clearance rate of 20 ml/min, you can conclude that
ahrayia [7]

Answer:

(B). The drug is reabsorbed.

Explanation:

Renal clearance rate determines the excretion of drugs into the urine during excretion. It is used to study the main process associated with a drug's renal excretion.

When the renal clearance rate is lower than GFR (glomerulus filtration rate), the drug is absorbed in the renal tubules. When the renal clearance rate is higher than GFR, the drug is secreted into the urine. When the renal clearance rate is equal to the GFR, the drug is neither reabsorbed nor secreted.

As for given drug, renal clearance is 20 ml/min (less than GFR), this drug will reabsorbed.

Thus, the correct answer is option (B).

Aleonysh [2.5K]
I believe the correct answer would be the third option. Our elements that comprise over 95% of the human body are <span>carbon, hydrogen, oxygen, nitrogen. Carbon and hydrogen is the backbone of any hydrocarbon or organic compound. The cells in our body are made up organic compounds thus our body is mostly composed of carbon and hydrogen. Oxygen is also present in high percent in our body since it is important for the processes of the cells. Also, nitrogen should be present in our body in large amount since it is present in proteins which is found in our body's cells and tissues.</span>
