Final answer:

Intercalated discs facilitate rapid cardiac muscle contractions through gap junctions, supporting heart function.


Explanation:

Intercalated discs play a crucial role in the rapid passing of contractions between cardiac muscle fibers. These discs contain gap junctions that allow the depolarizing current to flow between cells, facilitating the coordinated contraction of the heart. This electric coupling enables the swift transmission of action potentials, essential for the synchronized heart muscle contraction.
