Definition that contains right atrium
- coronary sinus a short sinus receiving most of the veins of the heart; empties into the right atrium
- right atrioventricular valve valve with three cusps; situated between the right atrium and the right ventricle; allows blood to pass from atrium to ventricle and closes to prevent backflow when the ventricle contracts
- tricuspid valve valve with three cusps; situated between the right atrium and the right ventricle; allows blood to pass from atrium to ventricle and closes to prevent backflow when the ventricle contracts
- inferior vena cava receives blood from lower limbs and abdominal organs and empties into the posterior part of the right atrium of the heart; formed from the union of the two iliac veins
- right ventricle the chamber on the right side of the heart that receives venous blood from the right atrium and pumps it into the pulmonary trunk
- vena cava either of two large veins that return oxygen-depleted blood to the right atrium of the heart
- postcava receives blood from lower limbs and abdominal organs and empties into the posterior part of the right atrium of the heart; formed from the union of the two iliac veins
- sinus coronarius a short sinus receiving most of the veins of the heart; empties into the right atrium
- atrioventricular node a node of specialized heart muscle located in the septal wall of the right atrium; receives impulses from the sinoatrial node and transmits them to atrioventricular bundle
- precava receives blood from the head and arms and chest and empties into the right atrium of the heart; formed from the azygos and both brachiocephalic veins
