Heart valves allow blood to flow one way and prevent it from flowing in the wrong direction. The tricuspid valve controls blood flow between the right atrium and right ventricle. The bicuspid or ...

The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs. The right ventricle is one of the heart’s four chambers.

Right atrium: This upper chamber receives unoxygenated blood from the body and ejects it through the tricuspid valve to the right ventricle.; Right ventricle: This lower chamber receives blood ...

Learn about the anatomy of the heart and how its chambers, valves, and vessels work together to maintain effective blood circulation throughout the body to sustain life.

Diffuse sickness of the atrium can cause very rapid and chaotic signals in the atrium resulting in atrial fibrillation or somewhat more organized rhythms called atrial flutter. Damage to the ventricle ...

Pacemakers regulate the right atrium and right ventricle to maintain a good heart rate and keep the atrium and ventricle working together. This is called AV synchrony.

End-diastolic volume is how much blood is in the ventricles after the heart fills up with blood, but before it contracts to pump the blood around the body. Doctors use end-diastolic volume to ...

X-ray study showed enlargement of the right ventricle and left atrium. On clinical grounds she was thought to have significant mitral regurgitation as well as stenosis.

As the opacified left atrium emptied into the left ventricle, an aneurysm that filled from the base of the ventricle was discovered (Fig. 3 B). The aneurysm, which showed systolic expansion, ...

The left ventricle is one of four chambers of the heart. It is located in the bottom left portion of the heart below the left atrium, separated by the mitral valve.
