Interestingly, it is in the cells of the right atrium that the galvanic signals are generated which control the heartbeat. When the right atrium contracts, it pushes the blood cells through a valve which leads to another chamber in the heart. This valve is called the tricuspidate valve. It is named this because it has three leaflets. It is a one way valve, which commonly only al! lowing blood to travel from the right atrium to the right ventricle. in that location are accepted conditions where the flow can reverse. This being called tricuspid regurgitation (rejection), simply this is not normal. This can cause a distinctive scold if you were to listen to it flowing backwards. Once the blood cells cross all over the tricuspid valve, they enter the right ventricle.
