systole
Contraction of the ventricles and atria is called systole. Relaxation is called diastole.
Relaxation = Diastole Contraction of the atria=Atrial systole Contraction of the ventricles = Ventricular systole
d. contraction of the ventricles
The period of time marked by contraction of the ventricles
during the systole phase of the heart contraction.
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.
The ventricles of heart have two states: systole(contraction) and diastole (relaxation). During diastole blood fills the ventricles and during systole the blood is pushed out of the heart into the arteries. The auricles contract anti-phase to the ventricles and chiefly serve to optimally fill the ventricles with blood.http://www.answers.com/systole
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
Trick question. Systole means contraction and is commonly assumed to mean ventricular systole - contraction of the ventricles. These both contract at the same time and as the right is full of deoxygenated blood and the left full of oxygenated blood both types are pumped during systole.
is the sthrenght of the last contraction of the ventricles of the heart, at the end of the cardiac cycle.
contraction phase and relaxation phase of the ventricles
