our blood pressure is measured in ______________
Blood pressure is measured in ‘millimetres of mercury’ (mmHg). The normal reading of blood pressure in a healthy person is 120/80mmHg.
Question 116 (ii)
Health Application A doctor reports blood pressure in millimetres of mercury (mm Hg) as a ratio of systolic blood pressure to diastolic blood pressure (such as 140 over 80). Systolic pressure is measured when the heart beats and diastolic pressure is measured when it rests. Refer to the table of blood pressure ranges for adults. Manohar is a healthy 37 yr old man whose blood pressure is in the normal category. If Manohar's systolic blood pressure is 102 mm Hg, then use the ratio from part (a) to predict his diastolic blood pressure.

Systolic pressure is measured when the heart beats and diastolic pressure is measured when it rests. Refer to the table of blood pressure ranges for adults. Manohar is a healthy 37 yr old man whose blood pressure is in the normal category. Calculate the ratio of average systolic to average diastolic blood pressures in the prehypertension category.
