The normal systolic pressure in human beings is:

The correct answer is 120 mm of Hg.

Key Points

• The normal systolic blood pressure in a healthy adult human is considered to be 120 mm of Hg, as defined by global medical standards.
• Systolic pressure refers to the maximum pressure exerted on artery walls during the contraction of the heart's left ventricle.
• A systolic blood pressure reading of less than 120 mm of Hg is regarded as normal, according to the American Heart Association (AHA).
• Blood pressure is typically measured in millimeters of mercury (mmHg) and is represented as a ratio of systolic to diastolic pressure, for example, 120/80 mmHg.
• Consistently high systolic pressure (≥130 mmHg) can indicate hypertension, which increases the risk of heart disease, stroke, and other health complications.

Additional Information

• Diastolic Pressure:
  • It is the minimum pressure in the arteries when the heart rests between beats.
  • The normal diastolic pressure is 80 mm of Hg.
  • A diastolic pressure reading of ≥90 mmHg is considered high and may indicate hypertension.
• Hypertension (High Blood Pressure):
  • A condition where the blood pressure consistently exceeds 130/80 mmHg.
  • It is a major risk factor for cardiovascular diseases, kidney damage, and stroke.
• Hypotension (Low Blood Pressure):
  • Occurs when blood pressure drops below 90/60 mmHg.
  • Can lead to dizziness, fainting, and in severe cases, shock.
• Blood Pressure Measurement:
  • Blood pressure is measured using a device called a sphygmomanometer.
  • The measurement includes two numbers: systolic (upper) and diastolic (lower) pressure.
• Factors Affecting Blood Pressure:
  • Age, stress, diet, physical activity, and underlying medical conditions can influence blood pressure levels.
  • Maintaining a healthy lifestyle, including a balanced diet and regular exercise, is crucial for blood pressure management.
