Heart Skeleton

Fibrous connective tissue that provides a point of attachment for cardiac muscle cells, electrically insulates the atria from the ventricles, and forms the fibrous rings around the valves.

Electrical Insulation

Materials or systems that prevent the passage of electrical current, used to protect, isolate, and contain electrical conductors.

Atria

The two upper chambers of the heart that receive blood from the veins and pump it to the ventricles.
