The correct Answer is:
To solve the question regarding the blood pressure measurement of 120/80 mm of Hg, we will break down the components of the blood pressure reading step by step. ### Step-by-Step Solution: 1. **Understanding Blood Pressure Measurement**: Blood pressure is expressed in two numbers, typically written as systolic pressure over diastolic pressure. The unit of measurement is millimeters of mercury (mm Hg). 2. **Identifying the Components**: In the reading 120/80 mm Hg: - The first number (120) represents the systolic pressure. - The second number (80) represents the diastolic pressure. 3. **Defining Systolic Pressure**: Systolic pressure is the pressure in the arteries when the heart beats and pumps blood. It is the maximum pressure exerted on the arterial walls. 4. **Defining Diastolic Pressure**: Diastolic pressure is the pressure in the arteries when the heart is at rest between beats. It is the minimum pressure in the arteries. 5. **Conclusion**: Therefore, in the blood pressure reading of 120/80 mm Hg, the term 120 specifically refers to the systolic blood pressure. ### Final Answer: The term 120 refers to the systolic blood pressure. ---
