What happens during the t wave in the heart?
During the T-wave the ventricles are repolarizing, preparing for the next beat.
The period during which the ventricles are depolarizing which precedes their contraction?
QRS wave
During what phase does the ventricles force blood through the aorta?
ejection period
What is the phase in the cardiac cycle in which the ventricles relax between contractions?
The ventricles relax during diastole.
What does systole refer to?
The period of time marked by contraction of the ventricles
What is meant by systole and diastole?
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
Contrast the four events answered in (a) in terms of whether the ventricles contract or relax?
diastole.systolic to diastolicThe ventricles relax during diastole
The pressure in the arteries during relaxation of the ventricles is know as?
systole
What occurs during left ventricular relaxation?
open
When is blood ejected from the ventricles?
during the systole phase of the heart contraction.
What does diastolic pressure measure?
Diastolic is the period at which your heart is relaxing and your ventricles are dilating (filling with blood).
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
