Blood flows through the right atrium into the right ventricle. The right ventricle pumps the blood to the lungs, where the blood releases waste gases and picks up oxygen. The newly oxygen-rich ...

Deoxygenated blood from the superior and inferior vena cava and the coronary sinus collect in the right atrium. From there, blood flows across the tricuspid valve into the right ventricle ...

The electrical impulse travels through the atrium and reaches the atrioventricular node (AV node), which is the normal connection to the ventricles, the bottom chambers of the heart that pump blood to ...

The mitral valve is positioned between the heart’s left atrium and ventricle. It opens to allow blood to flow into the left ventricle and closes to prevent backflow into the left atrium.

The left-hand side pumps oxygenated blood around the body. Each side of the heart consists of an atrium and a ventricle which are two connected chambers. The atria (plural of atrium) are where the ...

Small branches to the right atrium, ventricle, and conus or sinus node, are frequently observed. The RCA shows more displacement during the cardiac cycle than does the left coronary artery.

The normal mitral valve permits unrestricted antegrade diastolic flow from the left atrium to the left ventricle (LV) and effectively seals off the atrium from the ventricle during LV systole ...

This twisting results in the shape of the heart and the positioning of the atria and ventricles seen in adult amniotes. In lungfish, the heart is partially divided into a right and left atrium. The ...

This area is sufficient to allow a great deal of blood to flow from the left atrium (LA) to the left ventricle. When any disease process decreases the mitral valve area, mitral stenosis (MS ...

Blood flows through the right atrium into the right ventricle. The right ventricle pumps the blood to the lungs, where the blood releases waste gases and picks up oxygen. The newly oxygen-rich ...

The left-hand side pumps oxygenated blood around the body. Each side of the heart consists of an atrium and a ventricle which are two connected chambers. The atria (plural of atrium) are where the ...
