Verified step by step guidance

Understand the anatomy of the heart: The heart contains four chambers and valves that regulate blood flow between these chambers.

Identify the role of tendinous chords: Tendinous chords, also known as chordae tendineae, are fibrous cords that connect the papillary muscles to the tricuspid and mitral valves in the heart.

Explore the function of tendinous chords: These chords prevent the inversion or prolapse of the valves during ventricular contraction, ensuring that blood flows in the correct direction.

Differentiate from other options: Tendinous chords do not store calcium, transmit nerve impulses, or connect muscles to bones. Their primary role is related to heart valve stabilization.

Conclude with the correct function: The primary function of tendinous chords is to stabilize the heart valves, preventing backflow of blood and maintaining efficient circulation.
