The contraction of the heart and arteries by which the blood is forced onward and the circulation kept up; also, the contraction of a rhythmically pulsating contractile vacuole; -- correlative to diastole.
The contraction, or time of contraction, of the heart.
Period during the cardiac cycle when a chamber is contracting; thus, atrial systole, ventricular systole.
The contraction/ejection phase of the heartbeat.
The pumping phase of the heart's cycle
a contraction event of either the atria or ventricles.
The portion of the cardiac cycle in which the heart muscle contracts, forcing the blood the main blood vessels.
The period of atrial or ventricular contraction.
Systole is the phase of the heart beat during which the heart contracts, causing the blood within to be ejected.
The part of the cycle during which the muscle contracts to empty the heart is called systole. The filling portion is diastole.
in the cardiac cycle, when the heart contracts (pumps).
The contraction phase of the cardiac cycle during which blood leaves the ventricles.
The period of the cardiac cycle during which a heart chamber contracts to eject blood.
Period of the cardiac cycle during which the heart muscle contracts and pumps blood out and into the arteries.
The contraction of the ventricles that opens the semilunar valve and forces blood into the arteries. PICTURE
systole of , (), is the minimal volume of -cycle nonhomologous to zero.
Contraction of the heart, especially the ventricles
contraction of the heart chambers that forces blood outward
when the heart contracts and pumps the blood into the aorta and pulmonary artery.
The phase of the cardiac cycle in which the myocardium contracts and ejects blood from the ventricles.
Period of contraction of the heart during which blood is ejected from the ventricles.
The period during which the heart contracts, forcing blood out of the heart and into the rest of the body. The first (or upper) number in your blood pressure is the maximum pressure, which occurs during this phase.
The period of contraction of the heart muscle. The depolarisation period.
Period of contraction in the cardiac cycle when the heart squeezes or pumps the blood out of the chambers.
The time period when the heart is contracting. The period specifically during which the left ventricle of the heart contracts. See the entire definition of Systole
The phase in the cardiac cycle in which the myocardium of the ventricles is electrically and mechanically active (i.e., contracts and ejects blood).
the contraction phase of the heartbeat when the heart muscle squeezes. Return to the top
The period of cardiac contraction.
Means “to contract.†The time during which the heart muscle contracts to pump blood out. The higher number is a blood pressure reading.
Refers to the period of time during contraction of the ventricle(s), when blood is ejected from the ventricles into the aorta and pulmonary artery
The portion of the heart cycle during which the heart muscle is contracting.
Systole is the contraction of the chambers of the heart, driving blood out of the chambers. The chamber most often discussed is the left ventricle. However, all four chambers of the heart undergo systole and diastole in a timed fashion so that blood is propelled forward through the cardiovascular system.
