The relaxation phase of the heartbeat is called?

The relaxation phase of the heartbeat is called diastole. During diastole, the heart ventricles relax and fill with blood in preparation for the next contraction.


The terms systole and diastole refer respectively to the?

Systole refers to the phase of the heartbeat when the heart muscle contracts and blood is pushed out of the heart chambers. Diastole refers to the phase when the heart muscle relaxes and the heart chambers fill with blood.


Resting phase of the heart?

Diastole. It is the resting Phase. The Heart Chambers fill with blood. (Systole is the working or contracting Phase)


What is systole and diastole?

Systole and diastole describe the phase/state the heart is in during a heartbeat. Systole refers to the heart when contracted, and blood is pumped into the arteries. Diastole refers to the heart when it is relaxed and blood enters the upper chambers.


What coronary arteries fill with blood to deliver to heart during what phase?

Why does stroke volume decrease when heart rate increases?

When heart rate increases, there is less time for the heart to fill with blood before it contracts again. This results in a decrease in the amount of blood pumped out with each heartbeat, known as stroke volume.

What are the definition or meaning of diastole?

definiton or meaning of diastole : Refers to the phase of the cardiac cycle when the heart is relaxed. This phase of the cardiac cycle contributes to the lower number in blood pressure readings, called the "diastolic blood pressure." A value of greater than 90 on three or more different readings over time is used to define hypertension.


Sequence of events in one heartbeat?

During one heartbeat, the sequence of events is as follows: 1) The sinoatrial (SA) node generates an electrical impulse, initiating the heartbeat. 2) The electrical signal spreads through the atria, causing them to contract and push blood into the ventricles. 3) The electrical signal reaches the atrioventricular (AV) node, which delays the impulse slightly to allow the ventricles to fill with blood. 4) The signal then travels down the bundle of His and Purkinje fibers, causing the ventricles to contract and pump blood out of the heart.
