A blood pressure reading has two numbers: a systolic blood pressure and a diastolic blood pressure. The systolic blood pressure is the maximum pressure the blood exerts on the vessels when the heart is beating. The diastolic blood pressure is the pressure the blood exerts on the vessels in between heartbeats. Hypertension, or high blood pressure, begins when the systolic blood pressure remains above 140 or when the diastolic blood pressure remains above 90. Hypertension can be a result of increased blood flow through vessels or increased resistance to ...Read more
Sometimes...: Low blood pressure, if low enough, can decrease blood flow to the brain. Since blood carries oxygen, the person would then have low oxygen to the brain. The brain doesn't function well with low blood flow/oxygen and the person could experience light-headedness, confusion, etc. And may even pass out. ...Read moreSee 1 more doctor answer
Requires both muscle: to work harder to drive blood forward & ?es valve leaflet loads to block reverse blood flow. Heart muscle requires more blood flow for more work (more susceptible to damage of artery Ds), muscle gets thicker/stronger but also stiffer (no longer allows blood return from veins at low pressure) over time. Both lead to ?ed heart attack rates, enlargement, congestive failure, atrial fibrillation, etc. ...Read more

Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more
