It is called the systolic blood pressure and is given by the higher of the two numbers on your blood pressure reading. eg, if your blood pressure is 120/80, the systolic pressure is 120mmHg.
The actual pressure follows a wave-form. As the ventricle contracts and squeeze blood into the arteries the pressure rises (from the lower diastolic level) and as contraction continues the pressure peaks and then drops back as the contraction finishes and the heart begins to relax. So to be specific the pressure will depend upon what phase of contraction one is referring to. However generally speaking it is the peak, as explained above, that is referred to.
What else can I help you with?
As heart ventricles contract and then relax blood pressure inside of arteries change from?
systolic to diastolic
What is the name of the blood pressure measuered when the ventricles relax?
The blood pressure measured when the ventricles relax is called diastolic blood pressure. It is the lower number in a blood pressure reading, representing the pressure in the arteries when the heart is at rest between contractions.
Is the Systolic pressure is a measure of blood pressure when the ventricles relax and fill with blood?
No. I think the systolic pressure is when ventricles constrict and the blood goes out , while the diastolic pressure is when ventricles relax and fill with blood.
Do arteries have valves to allow blood to flow away from the heart?
No, they're aren't any valves in the arteries.
Ventricle force blood directly into what?
The ventricles contract and force the blood under pressure, past the semi lunar valves into the arteries. The closing of the bicuspid and tricuspid valves prevents back flow. At the same time the atria and ventricles relax and blood begins to flow back into them from the veins.
Which chambers make up a persons blood pressure?
Blood pressure is not made up of chambers. Blood pressure measurements include the systolic number, indicating the higher pressure when the ventricles contract, and the diastolic pressure, the pressure when the ventricles relax.
What is the phase in the cardiac cycle in which the ventricles relax between contractions?
The ventricles relax during diastole.
When the ventricles relax intraventricular pressure falls and?
blood is pushed against the semilunar valves, causing them to close
When the heart contracts what receives its blood supply?
Blood pressure is the force of blood against the inner walls of arterial blood vessels. Blood pressure rises when the ventricles contract and falls when the ventricles relax. Systolic pressure is the maximum pressure and diastolic pressure is the minimum pressure.
When atria relax ventricles do what?
When relaxed, the atria expand, and then the ventricles contract.
Contrast the four events answered in (a) in terms of whether the ventricles contract or relax?
diastole.systolic to diastolicThe ventricles relax during diastole
Describe how heart contraction and relaxation influence coronary blood flow?
When relaxation or diastole is occurring in the atria blood flows through the atria and the AV valves into the ventricles. When contraction or systole is occurring in the atria the remaining blood that doesn't flow through during relaxation is pushed into the ventricles. As the atria relax, the ventricles begin contracting; ventricular pressure rises, closing the AV valves. Ventricular pressure continues rising until it exceeds the pressure in the large arteries stemming from the ventricles. The SL valves are forced open and blood is expelled from the ventricles into the aorta and pulmonary trunk. During this phase the ventricles relax because the blood is no longer compressed in their chambers. Blood expelled into the aorta and pulmonary trunk backflows toward the heart, which then closes the SL valves. During the ventricle contraction the atria stays in relaxation, filling with blood and when blood pressure on the atrial side of the AV valves exceeds that in the ventricles, the AV valves are forced open and ventricular filling begin all over again.
