What vessels contain elastic fibers in the walls that are stretched during systole?
Capillaries
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
Is the blood pressure in systemic arteries greatest during atrial systole or ventricular systole?
ventricular systole
What is difference with systolic and diastolic?
SYSTOLIC: Relating to a systole or happening during a systole. But what is a systole? It is the contraction of the chambers of the heart(especially the ventricles) to drive blood into the aorta and pulmonary artery. DIASTOLIC: Relating to a diastole or happening during a diastole. But what is a diastole ? The widening of the chambers of the heart between two contractions when the chambers fill with blood is called a diastole.
During ventricular systole are AV valves closed?
yes during ventricular systole AV valves are closed.
What happens in the heart during Systole?
During systole the thick muscular walls of the ventricles contract. This happens to both sides of the heart at about the same time.The contraction of the ventricular muscle raises the pressure in the ventricle. The high pressure in the ventricle forces the bicuspid valve to close and forces blood up the aorta.
Pressure in the aorta will be greatest during?
"systole"
What is the Process that causes the last 30 percent of ventricular volume to fill?
ventricular systole
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
Would yo be able to feel a pulse during atrial systole only?
yes because during atria systole, the heart muscle tissue contracts.
Blood ejected from the ventricles enters which vessels during ventricular systole?
The right ventricle empties into the pulmonary arteries and the left ventricle empties into the aorta.
What valve opens during systole?
aortic and pulmonic
