Select the INCORRECT statement.
- ABlood pressure is directly proportional to the viscosity of blood.
- BIn women, usually the BP increases after menopause.
- Correct answerCThe hormone ADH reduces BP.
- DBlood loss in an accident decreases the BP.
Solution
Blood pressure is directly proportional to the viscosity of blood, as higher viscosity increases resistance to blood flow.
In women, blood pressure usually increases after menopause due to the decline in estrogen levels, which normally help keep blood vessels relaxed.
Blood loss in an accident decreases blood volume, which in turn decreases blood pressure.
The hormone ADH (Antidiuretic Hormone), also known as vasopressin, promotes water reabsorption in the kidneys and causes vasoconstriction. Both of these effects lead to an increase in blood pressure, not a reduction. Therefore, the statement that ADH reduces BP is incorrect.
Answer: The hormone ADH reduces BP.
