A. systole causes a complete emptying of all blood from the ventricle
B. systole increases the pressure in the ventricles ejecting blood out through the cardiac outflow tracts
C. systole occupies a longer period of time than does diastole.
D. systole is the phase of the cardiac cycle when the heart fills with blood.
E. None of the above
when the heart ventricular muscle contracts, squeezing blood out to the lungs/body

Is the blood pressure in systemic arteries greatest during atrial systole or ventricular systole?
ventricular systole
What is the time taken by atrial systole and ventricular systole?
0.4sec
Which part is atrial systole in ECG?
identify the portion of the ECG that represents the electrcal activity associated with atrial systole.
Would yo be able to feel a pulse during atrial systole only?
yes because during atria systole, the heart muscle tissue contracts.
What are ventricles doing atrial systole?
During atrial systole, the SA node ( power house for heart to keep on beating) is unable to send signals to ventricles. But heart has some back up power houses which take over, so the ventricles can still keep on beating but at a slower rate than normal during atrial asystole.
During atrial systole 70 percent of ventricular filling occurs?
No. Most (~70%) of ventricular filling occurs passively, without atrial contraction.
Is the blood pressure in systemic arteries greatest during atrial systole or ventricular systole?
ventricular systole
What is the time interval of atrial systole?
The time interval of atrial systole is typically around 0.1 seconds, representing the contraction of the atria to push blood into the ventricles. This phase occurs during the cardiac cycle as part of the heart's pumping action.
Who comes first atrial systole or ventricle systole?
Atrial systole -- The atrium contracts, then the ventricle.
Which is the phase of cardiac cycle in whitch the auricles contract?
The phase of the cardiac cycle in which the atria contract is called atrial systole. This occurs during the P wave on an ECG and helps to push blood from the atria into the ventricles.
Would yo be able to feel a pulse during atrial systole only?
yes because during atria systole, the heart muscle tissue contracts.
What is the time taken by atrial systole and ventricular systole?
0.4sec
Which part is atrial systole in ECG?
identify the portion of the ECG that represents the electrcal activity associated with atrial systole.
What percent of blood pass from the atria to the ventricles before the atrial walls contract?
70% the remaining 30% is pushed into the ventricles during atrial systole
What are ventricles doing atrial systole?
During atrial systole, the SA node ( power house for heart to keep on beating) is unable to send signals to ventricles. But heart has some back up power houses which take over, so the ventricles can still keep on beating but at a slower rate than normal during atrial asystole.
Does the p wave in an ekg indicate atrial depolarization?
No it does not. Atrial repolarization is generally not visible on the telemetry strip because it happens at the same time as ventricular depolarization (QRS complex). The P wave represents atrial DEpolarization (and atrial systole). Atrial repolarization happens during atrial diastole (and ventricular systole).
Does atrial systole occur before or after the firing of the sinoatrial node?
The SA node makes the action potential for the heart. Atrial systole must occur after the action potential.
