The function of the right atrium is to receive deoxygenated blood from the body (through the superior and inferior vena cavae, and the coronary sinus) and pump it into the right ventricle, which then pumps it to the lungs to be reoxygenated.
The function of the tricuspid valve is to prevent blood from flowing back into the atrium when the right ventricle contracts.

The rooms in a Roman villa were called the same as the rooms in the domus. There was the Vestibulum which was a small entrance hall. Then there was the Atrium which was the formal entrance hall with sometimes ala, or "wings" opening from the atrium. There were small rooms off the atrium called Cubicula which could be either bedrooms or used for other purposes. There was the Tablinum whuich was an office or study. There was the Triclinium which was the dining room. Most villas also had a room or rooms off the garden which was called an Exedra.
