| right atrium |
In anatomy, the atrium (plural: atria) is the blood collection chamber of a heart. It has a thin-walled structure that allows blood to return to the heart. There is at least one atrium in an animal with a closed circulatory system. In fish, the circulatory system is very simple: a two-chambered heart including one atrium and one ventricle. In vertebrate groups that evolved later, the circulatory system is much more complicated. ...

| right atrium |
The heart has four chambers. A partial septum separates right and left atria. The right atrium is best developed and receives the sinus venosus. The sinus enters the right atrium through the sinoatrial canal.

| right atrium |
The upper (or "priming") pumping chamber on the right side of the heart. The right atrium sits above the tricuspid valve and gently forces blood across the tricuspid valve into the right ventricle. This actions "primes" the lower pumping chamber to improve efficiency. At the same time, the right atrium provides a temporary storage site for blood returning from the lungs during the time that the right ventricle is actually squeezing.
