F10 F11 F12 Home F6 SysRa Prnt F4 F5Explanation / Answer
12) the higher the pressure exerted by the heart, the faster blood will flow. Same is the relationship shown here.
13) heart generates this blood pressure. It depends on the flow rate and the resistance of blood vessel to blood flow.
14) blood pressure of 150 mm Hg would be considered as hypertension. There are basically 2 pressures. One is systolic other is diastolic which in normal conditions is 120/80 mm Hg
Systolic pressure upto 140 mm Hg is considered in a normal range
Diastolic pressure upto 90 mm Hg is considered normal.
