The contraction of heart, more specifically, heart or cardiac muscle tissue is called systole. It happens in the both atria and ventricles and the increased pressure due to contraction is, thus, called systolic pressure.

∙ 6y agoA small cluster of cardiac muscle cells called the sinoatrial nodes make the heart contract. When these are triggered by the nervous system, they give off electrical impulses into the heart muscles. If these cells provide signals that are inconsistent or insufficient, they can be augmented with an artificial pacemaker.

∙ 13y agoCalled systole or systolic when the heart contracts (squeezes) to pump blood out into the ascending aorta. diastole or diastolic is the heart relaxing to fill with blood from the veins. It is checked by a doctor or nurse with the band that goes around your upper arm and is pumped up then slowly deflated.

How does the heart contract or relax?
The heart contracts and relaxes during a cardiac cycle.
Is it true when alcohol is consumed the heart function is depressed and the ability of the heart to contract and move blood is reduced?
When alcohol is consumed, the heart function is increased and the ability of the heart to contract and move blood is increased
Is the heart involuntary or voluntary?
the heart is and involuntary muscle because you cannot contract the muscle.
What is an asystole?
An asystole is an absence of systole, the inability or failure of the heart to contract.
What is happening during a complete heart block?
Complete heart block is where the electrical impulses from the SA node of the heart cannot reach the ventricles along the normal pathway. Instead the atrial contract from the SA node singles and the ventricles contract from the ventricular cells
Do the ventricles contract at the apex or at the base of the heart?
Not really sure what you mean by the base, the ventricles contract from the Apex (which is at the bottom) upwards.
What are myogenic cells?
A myogenic heart is a heart that can naturally contract and relax and doesn't need to receive impulses from a nerve to make it contract. your heart is a Myogenic heart
What two chambers contract last in the heart?
During diastole the atria fills with blood.
What is the contract phase of the heart?
systole.
How the heart is signaled to contract?
uhh... what?
When alcohol is consumed the heart function is increased and the ability of the heart to contract and move blood is increased.?
When alcohol is consumed, the heart function is increased and the ability of the heart to contract and move blood is increased
When alcohol is consumed the heart functions is increased and the ability of the heart to contract and move blood is increased?
When alcohol is consumed, the heart function is increased and the ability of the heart to contract and move blood is increased
What contract together to pump blood?
The ventricles contract to pump blood out of the heart.
Where is blood pumped when ventricles contract?
Into the heart
How does the heart contract or relax?
The heart contracts and relaxes during a cardiac cycle.
When electrical impulse arrive at the heart and the heart is ready to contract is called?
diastylic
What is the muscle when the heart forces blood?
The ventricles are the lower heart chambers that contract to pump blood. The upper chambers, atria, also contract, but to a lesser degree.
