Tricuspid valves
Tricuspid Valve
The Tricuspid Valve (pronunciation: /ˈtraɪˌkʌspɪd ˈvælv/) is one of the four valves in the human heart, located between the right atrium and the right ventricle. The term "tricuspid" refers to the three flaps or leaflets that make up the valve, which open and close to regulate blood flow and prevent backflow.
Etymology
The term "tricuspid" is derived from the Latin words "tri" meaning three, and "cuspis" meaning point or prong. The name reflects the valve's three-pointed structure.
Function
The primary function of the Tricuspid Valve is to prevent the backflow of blood from the right ventricle into the right atrium. When the right atrium contracts, the tricuspid valve opens, allowing blood to flow into the right ventricle. When the right ventricle contracts, the tricuspid valve closes, preventing blood from flowing back into the right atrium.
