Define systolic and diastolic blood pressure?
Blood Pressure: The force at which blood flows through the arteries in the body. Systolic: Refers to the pressure on the arteries as the heart contracts (squeezes). Diastolic: Refers to the pressure on the vessels as the heart relaxes.
What causes a high diastolic but low systolic reading?
When a person is evaluated for high blood pressure), 2 values are recorded: systolic and diastolic blood pressures. Systolic (the higher number) is the pressure in the arteries when the heart contracts; diastolic (the lower number) is the pressure when the heart rests between contractions. A blood pressure reading is recorded as systolic /diastolic pressure, or "systolic over diastolic." Both systolic and diastolic blood pressures are measured in millimeters of mercury (mmHg). An example of how to read a blood pressure measurement is "120 mmHg/80 mmHg" or "120 over 80." High blood pressure in adults is defined as having either a systolic pressure of 140 mmHg or more, or having a diastolic pressure of 90 mmHg or more. In some people with high blood pressure, both systolic and diastolic pressures are high. However, older people often have a higher systolic pressure with a normal. This condition is called isolated systolic hypertension, which is still considered high blood pressure. In older adults because the arteries reduce in elasticity, they do not expand as easily causing an increase in the systolic blood pressure (Imagine the same quantity of blood flowing through a vessel that doesn't expand. It gets really crammed in there causing systolic blood pressure to increase). But because diastolic pressure is the minimum pressure exerted on the arteries during diastole, there isn't much distension and contraction of the arteries. Thus, reduced elasticity does not effect diastolic pressure causing a normal blood pressure reading.
Is blood pressure the pressure of blood in the arteries?
Yes, blood pressure is a measure of the pressure exerted on your arterial walls as the heart pumps blood throughout the body (systolic) over the pressure when your heart is relaxed (diastolic).
As heart ventricles contract and then relax blood pressure inside of arteries change from?
systolic to diastolic
What is the difference between systolic pressure and diastolic pressure?
systolic pressure when ventricals are contracting while during diastole they are in relaxed state
Explain the readings for systolic and diastolic pressure that is what is actually happening?
What does the BP numbers mean? The number on the top is the systolic blood pressure and the number on the bottom is the diastolic blood pressure. The systolic BP is the pressure in the arteries right when the blood is pumped out of the heart, therefore the pressure is bigger. The diastolic BP is the pressure in the arteries after the blood has been pumped out and before the next heart contraction. At this moment, the heart is relaxed and the pressure is much lower.
What is the systolic and diastolic?
Systole is the top number of a blood pressure reading. It is the heart contracting forcing blood out. Indicated by the first heart sound. Diastole is the bottom number of a blood pressure reading. It is the heart relaxing bringing blood back in.
The difference between systolic and diastolic pressures?
Systolic BP should always be higher than diastolic BP.The number on the top is the systolic blood pressure and the number on the bottom is the diastolic blood pressure. The systolic BP is the pressure in the arteries right when the blood is pumped out of the heart, therefore the pressure is bigger. The diastolic BP is the pressure in the arteries after the blood has been pumped out and before the next heart contraction. At this moment, the heart is relaxed and the pressure is much lower.
What is the pressure in the arteries during relaxation of the ventricles called?
Blood can only enter an artery, be it the aorta, when the left ventricle contracts, or the pulmonary arteries, when the right ventricle contracts, which both occur at the same time after ventricular systole which is contraction. Therefore, the answer is contract.
What is the highest pressure against the blood vessels?
systolic, its the number on top, that's why that number is larger
How does the pulsating blood pressure in the largest arteries relate to their structure?
It reveals their elasticity. When the heart contracts and forces blood into the large arteries near the heart, they stretch to accommodate the greater blood volume (systolic pressure). Then, as the blood continues on in the circuit, their walls recoil, keeping pressure on the blood which keeps it moving (diastolic pressure).
Why is there a variation in systolic and diastolic pressure among members in different age groups and different genders?
As we age, our arteries lose the elasticity that allows the systolic/diastolic to be within the norms. Without that flexibility, the differences between systolic & diastolic will be greater. Such as the diastolic will decrease. The normal upper limit of pulse pressure is 60 mm. In example: 120/80 would be only 40. Well within. With hardening of the arteries, the difference might be something like 120/50-60, and so forth. This explains the differences between age groups. Different genders don't make any difference.
