If the left av valve does not close all the way what happens when the left ventricle contracts?
Blood is pumped back into the left atrium (the wrong direction) as well into the aorta (the right direction)
What happens when the ventricles of your contract?
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 happens in the right atrium?
The atria are the two upper chambers of the heart (the ventricles are the lower two) The atria are the 'filling' chambers, so blood entering the heart passes through the atria first, which then push it down into the ventricles. The two largest veins in the body (the superior and inferior venae cavae) empty deoxygenated blood returning from the body into the right atrium. The right atrium then contracts, pushing the blood into the right ventricle. The right ventricle then pumps the deoxygenated blood to the lungs where it is oxygenated. After leaving the lungs, the newly oxygenated blood is returned via the pulmonary veins into the left atrium. The left atrium then contracts and pushes the blood into the left ventricle, which pumps the oxygenated blood around the rest of the body.
As the left ventricle contracts the blood is prevented from going back into the left atrium by a one-way valve called the?
The Mitral Valve is positioned between the left atrium and the left ventricle. Closing of the mitral valve prevents the blood from flowing back to the left atrium.
What happens when the ventricles of heart contract?

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.
How does blood from the lungs get to the heart?
The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium of the heart. As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricle is full, the mitral valve shuts.
How does blood get from the lungs to the heart?

Where does blood pumped by the left ventricle pass through?
Blood enters the left ventricle from the left atrium by passing through the mitral valve. The mitral valve functions to prevent blood from flowing back into the left atrium when the left ventricle contracts.
What happen when the right atrium contracts?
At the beginning of the cardiac cycle after they receive an action potential from they synoatrial node. After a short pause, they produce the 'lubb' sound as the atrioventricular valves close to prevent back flow of blood.
What does the left atrium 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.
What is the third chamber of the heart that the blood reaches?
there are 4 chambers of the heart. the left and right atrium and the left and right ventricle. the left atrium is where the blood enters the heart and leaves through the left ventricle and the opposite for the only side only to the lungs instead of the body
