1.	Question : (a) Whatis being shown in the given Fig. A and B ?(b)Name the instrument used to measure this value.(c)Why is their difference in the reading in Fig. A and B ?(d)Discuss some common reasonsthat may lead to increase in thisvalue.
Answer» Solution :(a) The given figure shows MEASUREMENTOF blood pressure. (b)Blood pressure is measured by the instrument of blood pressure. (c)Fig. A shows systolic pressure while Fig. B showsdiastolic pressure. The force that blood EXERTS against the WALL of a vessel is called blood pressure. This pressure is much greater in arteires than in veins. The pressure of blood inside the arteryduringventricularsystole (contraction) is called systolic pressureand pressure in arteryduringventricular diastole (relaxation) is called diastolic pressure. The normal systolic pressure is about120 mm and distolic is 80 mm of Hg. Since, during contraction the BPincreasesand duringrelaxation the BPdecrease, hencethe difference. (d)Common reasons for increase in BP that leadsto Hypertension are : (i) GENETIC factors (ii)Sedentary life style (iii)Obesity (iv)Poor eating habits (v)Stress.
