From there, blood flows across the tricuspid valve into the right ventricle, where it is sent to collect oxygen in the lungs. The oxygenated blood flows back to the heart via the left atrium ...

are called the left and right atrium. The right atrium and right ventricle work together to receive the blood that has just traveled throughout the body and move it into the lungs. There ...

Blood flows through the left atrium into the left ventricle. The left ventricle pumps the oxygen-rich blood to all parts of the body. Do right and left seem backward? That's because you're looking ...

P-mitrale occurs when the depolarization of the right atrium and left atrium are both visible in the P wave. This is seen as a notch in the P wave and occurs when the left atrium is markedly ...

The septum separates the right-hand and left-hand side of the heart. The tricuspid valve separates the right atrium and right ventricle. It opens due to a build-up of pressure in the right atrium ...

An atrial septal defect of the secundum type is relatively common and occurs from failure of the septum secundum to develop. This results in a communication between the left and right atrium ...

The septum separates the right-hand and left-hand side of the heart. The tricuspid valve is located between the right atrium and right ventricle and opens due to a build-up of pressure in the ...
