What else can I help you with?
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
The atrioventricular valves are closed during the entire period of?
The atrioventricular valves are closed during the entire period of ventricular contraction to prevent blood from flowing back into the atria. This closure ensures that blood is pushed out of the ventricles and into the arteries.
What is the phase in the cardiac cycle in which the ventricles relax between contractions?
The ventricles relax during diastole.
What is the period of isovolumetric contraction is immediately followed by?
The period of isovolumetric contraction is immediately followed by the period of ventricular ejection in the cardiac cycle. During isovolumetric contraction, the ventricles contract while all valves are closed, and this is followed by the opening of the semilunar valves to allow blood to be ejected from the heart during ventricular ejection.
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
Does the tricuspid valve open during is ventricular contraction?
No, the tricuspid valve does not open during ventricular contraction. During this phase, known as systole, the ventricles contract to pump blood out of the heart, which causes the pressure in the ventricles to rise and forces the tricuspid valve to close. This closure prevents backflow of blood into the right atrium. The tricuspid valve opens during diastole, when the ventricles relax and blood flows from the atria into the ventricles.
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
What does diastolic pressure measure?
Diastolic is the period at which your heart is relaxing and your ventricles are dilating (filling with blood).
