Exercise 1 (20 marks) 1. What happens to the blood pressure and heart rate when the arterial resistance is increased? When arterial resistance is increased‚ the blood pressure increases and heart rate decreases. For instance‚ when arterial resistance increased to 150%‚ systolic blood pressure increases to 132.8mmHg‚ diastolic pressure increases to 82.1 mmHg‚ and heart rate decreased to 51.8/min. 2.
