What is the phase in the cardiac cycle in which the ventricles relax between contractions?
The ventricles relax during diastole.
What is the term that refers to the portion of the cardiac cycle when the ventricles contract and eject blood from the heart?
Systolic pressure
Which phase in cardiac cycle is systolic pressure?
Blood flows into the relaxed atria while the ventricles contract. <rephrased> The ventricles contract, carrying blood into the aorta, and blood flows into the relaxed atria.
Relaxation of the ventricles is?
Is the beginning of the cardiac cycle when the ventricles start to relax all four chambers are in diastole.
What part of the cardiac cycle is associated with the QRS complex?
The cardiac cycle refers to a complete heartbeat, including the systole and diastole. The QRS complex occurs during the depolarization of the right and left ventricles of the human heart.
Cardiac cycle when do you hear the first heart sound snd second?
when the ventricles closes and between the atria and the ventricles.
Coronary blood flow is greatest during what phase of the cardiac cycle?
diastolic
What is produced when the heart contracts?
What are you asking? The heat consists of 4 chambers (in humans) that contract (squeeze) and force blood through out the body, with the cycle constantly replenishing oxygen into the blood and delivering it to the rest of the body, returning the blood to the heat, and the cycle continues.
What is a terminal systole?
is the sthrenght of the last contraction of the ventricles of the heart, at the end of the cardiac cycle.
Are both sets of valves closed during the cardiac cycle?
Pulmonary and aortic valves are semilunar valves having three semilunar cusps each. these valves open with the free ends facing the vessels when the heart contracts and closes when heart relaxes thus preventing regurgitation
What are the two main phases of a heartbeat?
There is the contraction of the atria and the contraction of the ventricles. When the atria contract, the AV valves are open, allowing the blood to fall into the ventricles. The AV valves then close, and the ventricles contract, pumping the blood out into the arteries.
Which is the phase of cardiac cycle in which the auricles contract?
The auricles will contract during the systolic phase of the cardiac cycle. This is one of the numbers that is measured when a patient has their blood pressure taken.
