Step 1: Understand normal blood pressure.
The normal blood pressure for a healthy adult human is typically around
120/80 mmHg.
- The first number (120) is the systolic pressure, which is the pressure when the heart beats.
- The second number (80) is the diastolic pressure, which is the pressure when the heart rests between beats.
Step 2: Conclude.
The correct normal blood pressure is
120/80.
