The correct statement is:
**Higher blood pressure, and the heart must work harder to pump blood.**
When blood thickens, it increases the viscosity of the blood, which can lead to higher blood pressure. The heart has to exert more force to pump the thicker blood, resulting in the heart having to work harder.
**Higher blood pressure, and the heart must work harder to pump blood.**
