The "beat" of your heart is the contraction of the right and left ventricles.
The right atrium passes blood from the body into the right ventricle -- when the ventricle contracts, it forces shut the valve leading back to the atrium, and the blood is pushed into the pulmonary arteries that lead to the lungs.
The blood returns from the lungs to the left atrium, and flows into the left ventricle. When the left ventricle contracts, the blood is pushed out of the ventricle into the aorta, the body's main artery, to be carried through the arterial system to the various parts of the body.
What else can I help you with?
Where is blood pumped when ventricles contract?
Into the heart
What happens when your ventricles of your heart contact?
When the ventricles of your heart contract, blood is pumped out of the heart into the major arteries. The left ventricle pumps blood into the aorta, and the right ventricle into the pulmonary artery.
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 contract together to pump blood?
The ventricles contract to pump blood out of the heart.
What happens when ventricales contracts?
When the ventricles contract, they pump blood out of the heart and into the arteries for circulation throughout the body. This contraction is part of the cardiac cycle and is responsible for the main pumping action of the heart.
Why is it an advantage for the ventricles to contract from the bottom?
The pulmonary artery and the aorta lead upward and away from the ventricles. Since the ventricles contract from the bottom, blood is more efficiently pushed out of the heart.
What are the electrical impulses in the heart that are relayed to the ventricles by what?
A junction box, also known as the AV node, is how electrical impulses in the heart are relayed to the ventricles. The ventricles help make the muscle contract and then pump the blood.
What is cardiac preload?
it is the amount of blood available for the heart to pump when the ventricles contract
What fibers in the heart cause the ventricles to contract?
pukinje fibers
What happens to A-V valves during ventricular contraction?
As the ventricles of the heart contract the pressure in the ventricles rises beyond that of the atria. This pressure differential causes the AV valves to shut.
What happens to A V valves during ventricular contraction?
As the ventricles of the heart contract the pressure in the ventricles rises beyond that of the atria. This pressure differential causes the AV valves to shut.
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
