Hypertension (High Blood Pressure)

120/80 mm Hg is the NORMAL blood pressure, not hypertension. Hypertension means the pressure stays higher than 120/80. NCERT says if repeated checks read 140/90 or higher, it is hypertension. So 120/80 is the healthy value you should remember as the reference point.

The first number, 120 mm Hg, is the systolic pressure, also called the pumping pressure. It is the pressure when the ventricles contract and push blood out. The second number, 80 mm Hg, is the diastolic pressure, also called the resting pressure, measured when the heart relaxes. Both are measured in mm Hg (millimetres of mercury).

NCERT states that if repeated checks of blood pressure of an individual read 140/90 (140 over 90) or higher, it shows hypertension. Note the word 'repeated' and 'or higher'. A single high reading is not enough; it must be repeatedly high. This exact 140/90 value is a common one-mark NEET fact.

Yes. Hypertension is simply the medical term for blood pressure that is higher than normal. NCERT lists it as 'High Blood Pressure (Hypertension)'. Both words mean the same disorder, so in NEET they are used interchangeably.

NCERT clearly says high blood pressure leads to heart diseases and also affects vital organs like the brain and kidney. So the three organs to remember are heart, brain and kidney. This is a frequently asked recall point.

The normal blood pressure is 120/80 mm Hg, where 120 mm Hg is the systolic pressure and 80 mm Hg is the diastolic pressure.

If repeated checks show a blood pressure of 140/90 mm Hg or higher, the person is said to have hypertension.

Blood pressure is measured in mm Hg, that is millimetres of mercury pressure.

High blood pressure leads to heart diseases and also affects vital organs like the brain and kidney, so it damages several important organs at once.

Systolic pressure (120 mm Hg) is the pumping pressure, measured when the ventricles contract. Diastolic pressure (80 mm Hg) is the resting pressure when the heart relaxes.
