Verified step by step guidance

Step 1: Begin by identifying the anatomical structures involved in the heart's function. The atrioventricular valves (tricuspid and mitral valves) are responsible for preventing backflow of blood into the atria during ventricular contraction.

Step 2: Understand the role of the papillary muscles. These muscles are located in the ventricles and contract during systole to prevent the atrioventricular valves from inverting or prolapsing into the atria.

Step 3: Learn about the chordae tendineae. These are tendinous structures that connect the atrioventricular valves to the papillary muscles. They act as anchors, ensuring the valves remain closed during ventricular contraction.

Step 4: Eliminate incorrect options based on their anatomical relevance. For example, the ligamentum arteriosum is a remnant of fetal circulation, the round ligament is associated with the liver, and the fascia lata is a connective tissue structure in the thigh.

Step 5: Conclude that the correct answer is chordae tendineae, as they are the specific tendinous structures connecting the atrioventricular valves to the papillary muscles in the heart.
