The connective tissue rings that surround and anchor all four heart valves are called annuli fibrosi . They play a crucial role in maintaining the shape and function of the valves, as well as serving as an electrical insulator for the heart. Importantly, this structure ensures proper valve operation during the cardiac cycle. ;
The connective tissue rings surrounding the heart valves are known as annuli fibrosi, which provide structural support and insulation for proper heart functioning. These rings ensure that valves open and close correctly and withstand the pressure of blood flow. They play a significant role in coordinating the heart's rhythm and overall function.
