The ventricles contract to pump blood out of the heart.

∙ 6y agoBoth chambers contract but the upper chambers (atria) contract at a much lower pressure than the lower ones (ventricles). The contraction and relaxation of the chambers can be measured and noted as systolic pressure. I remember the difference best by: diastolic = dilate. That then leaves the second term to mean higher pressure (systolic).

What is ventricular contractions?
It is the muscular contraction of the heart muscles to pump blood out of the heart. The right ventricle contracts to send blood through the pulmonary arteries, and the left ventricle contracts to send blood into the aorta.
What is the cardiac muscles function?
It contracts causing the heart to pump and move more blood.
What is another name for ventricular contraction?

A muscular pump that forces blood through blood vessels?
The heart is the muscular pump which pushes blood through blood vessels, to reach all our body cells with vital nutrients and oxygen, as well as removing some waste products.
What does the left artriam do?
The left atrium is like a "turbocharger" for the left ventricle of the heart. It fills with oxygenated blood from the lungs, then contracts to pump the blood into the left ventricle. Here, the ventricle then contracts to pump the oxygenated blood all around your body.
Why do they say that the heart is a muscle?
Because your heart is a muscle, a cardiac muscle. a muscles job is to contract an that is exactly what the heart does, it contracts to pump blood.
In the heart what job dos the muscle tissue have?
The heart is made up of muscle tissue (cardiac muscle). The muscle tissue contracts to pump blood.
Where does blood flow when the ventricle contracts?
Blood flows to the heart when the ventricle contracts
