When after contraction of ventricles of heart, blood is propelled into circulatory system (both systemic and pulmonary circulation) and that pressure is called systolic pressure, witch dilates the aorta and large(and small also) arteries. When ventricles relax in diastole aortic (and pulmonary) valves close down and then aorta and large (and small also)arteries contract, witch are dilated during systole. Peripheral resistance in closed system maintain the lower blood pressure called diastolic blood pressure.
What else can I help you with?
Is diastolic pressure the vascular pressure created during the pulmonary resting phase?
No. Diastolic pressure is the (lowest) arterial pressure that occurs just before the heart beats.
When is diastolic pressure measured?
during the period when the heart is relaxed between beats and pressure is lowest
What is the medical term meaning lowest blood pressure in the arteries when the heart muscle is relaxing?
Diastolic pressure.
When is diastolic measured?
during the period when the heart is relaxed between beats and pressure is lowest
What is the lowest pressure that remains in the arterial system during ventricular relaxation?
this is called the diastolic pressure meaning when the heart is in diastole. The diastolic number is the bottom number in common blood pressure. i.e. in a pressure 120/80 the lowest measured pressure is 80mmHg during ventricular relaxation
How does sphygmonamometer work?
A sphygmomanometer is a device which measures blood pressure. It works by reading both the systolic, which is the peak pressure as the heart contracts, and diastolic, which is the lowest pressure as the heart relaxes.
Blood pressure that remains between heart contractions?
Diastolic Blood Pressure
What does the bottom number mean in blood pressure?
The Diastolic Pressure, is the lowest pressure in an artery in the moments between beats when the heart is resting. http://www.netdoctor.co.uk/health_advice/examinations/measuringbloodpressure.htm
Where will blood be at the lowest pressure in someone who is standing upright?
If you mean, what is the lowest blood pressure, then the answer is around 60 in an average person. Blood pressure is relatively consistent through out the body, so the lowest pressure would be seen when the heart is resting (also know as diastolic blood pressure).
Can the diastolic pressure ever be higher than the systolic blood pressure?
No The systolic pressure is the highest pressure during the ejection of blood (pumping) from heart. The diastolic pressure is the blood pressure when the ventricles are filling up with blood before pumping the blood out.
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.
Is diastolic pressure equal to heart rate?
Systolic blood pressure is when the left ventricle contracts (first number), diastolic pressure is when the left ventricle relaxes (second number).
