What is the alternating relaxation and contraction of the heart called?
Diastole is the relaxation phase. Systole is the contraction phase. If you put these phases together you have the Cardiac Cycle...
Which is the phase of cardiac cycle in whitch the auricles contract?
Systole is the correct answer
What is the phase of the cardiac cycle that is caused by the sliding of actin and myosin?
Systole
When do the AV valve close during the cardiac cycle?
AV valves close during the systole phase of the cardiac cycle.
What is a contraction phase of the heartbeat?
The cardiac cycle of the heart has two phases - the diastole phase and systole phase. In the systole phase, the ventricles contract and pump blood into the arteries.
What does the term systole mean?
Systole is the period of heart contraction within the cardiac cycle.
During which phase of the cardiac cycle do the ventricles relax and fill with blood?
diastole is when all 4 chambers of the heart are at rest after a cardiac cycle systole is the term used to describe the heart during a contraction
What is systole phase of the heart?
Refers to the phase of the cardiac cycle when the heart is in its contracted state. This phase of the cardiac cycle contributes to the upper number in blood pressure readings, called the "systolic blood pressure." A value of greater than 140 on three or more different readings over time is used to define hypertension
What event of the cardiac cycle is arterial blood pressure at its highest?
systole
What is a complete cycle of a heart contraction and relaxation called?
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
What do you know about heart systole?
Heart systole refers to the phase of the cardiac cycle when the heart muscle contracts to pump blood out of the chambers (ventricles) into the circulatory system. This contraction leads to an increase in blood pressure within the arteries, pushing blood to the rest of the body. Systole is typically followed by diastole, the relaxation phase of the heart.
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.
