Question
Conditions of extreme dehydration result in the subsequent high concentration of ______ in the blood.
Multiple choice question.
- erythropoietin
- renin
- ADH
- calcitonin
Solution
The correct answer is ADH.
Step 1: Understand the question. The question is asking what substance becomes highly concentrated in the blood under conditions of extreme dehydration.
Step 2: Know what each option does.
- Erythropoietin is a hormone that stimulates the production of red blood cells.
- Renin is an enzyme that helps control blood pressure.
- ADH (Antidiuretic hormone) helps regulate water balance in the body.
- Calcitonin is involved in the regulation of calcium and phosphate levels in the blood.
Step 3: Choose the correct answer. In conditions of extreme dehydration, the body would need to conserve water. ADH does this by reducing the amount of water excreted in the urine. Therefore, the concentration of ADH would be high in the blood during extreme dehydration.
