Which valve in the heart that stops the oxygenated blood from going backwards during systole of the ventricles?
The valve that prevents oxygenated blood from flowing backward during ventricular systole is the aortic valve. Located between the left ventricle and the aorta, it opens to allow blood to be pumped into the aorta and closes to prevent the backflow of blood into the heart once the ventricles relax. This ensures efficient circulation of oxygenated blood throughout the body.

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
Name of the kind of blood ejected during systole?
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.
The pressure in the arteries during relaxation of the ventricles is know as?
systole
When is blood ejected from the ventricles?
during the systole phase of the heart contraction.
What is the phase of ventricular contraction called?
It is called systole. This is when the ventricles contract and eject blood into the lungs (from the right ventricle) or into the systemic circulation (from left ventricle).
When is blood pressure in the systematic arteries the greatest?
Blood pressure in the systemic arteries is greatest during systole. Systole is the part of the heart cycle during which the ventricles contract.
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
What heart valves are closed during systole?
In late diastole (relaxation phase), the semilunar (pocket) valves close, due to decreasing arterial pressure, to prevent blood flowing back into the ventricles. These stay closed during atrial systole. (But open again during ventricular systole.)Then, as the ventricles contract during ventricular systole, the bicuspid and tricuspid valves close to prevent blood from flowing back to the atria.So, it really depends on which phase of the contraction we are looking at.(Ed: format)
What are ventricles doing atrial systole?
During atrial systole, the SA node ( power house for heart to keep on beating) is unable to send signals to ventricles. But heart has some back up power houses which take over, so the ventricles can still keep on beating but at a slower rate than normal during atrial asystole.
How many seconds does the Ventricular systole last?
The ventricular systole lasts for about 0.3 seconds, during which time the ventricles of the heart contract to push blood out into the arteries.
When do the atria contact?
The atria contract during the cardiac cycle's atrial systole phase, which occurs just before the ventricles contract. This contraction helps push blood from the atria into the ventricles, completing the filling of the ventricles before they contract during ventricular systole. Atrial contraction is facilitated by electrical signals from the sinoatrial (SA) node, ensuring synchronized heart function.
What is the function of the AV valve?
AV valves stop the back flow of blood from ventricles to atrium during ventricular systole
