If reabsorption does not occur in nephrons what effect will it have on the body?
Answer and explanation
Correct answer: Unnecessary loss of water and useful substances will occur
The governing concept is selective reabsorption during urine formation. Filtration moves small substances from blood into the nephron tubule, and the filtrate can include water, glucose, amino acids, and needed ions as well as wastes. Reabsorption normally returns useful materials and much of the required water to the blood. If it stopped, these substances would remain in the filtrate and be lost in urine, causing dehydration and serious imbalance. Hence option A is correct.
