The chordae tendineae are fibrous cords that attach the papillary muscles of the heart to the atrioventricular (AV) valves, specifically the mitral and tricuspid valves. They play a crucial role in preventing the valves from inverting or prolapsing during ventricular contraction, ensuring proper blood flow direction. By anchoring the valves, the chordae tendineae help maintain the integrity of the heart's structure during the cardiac cycle.

Are the chordae tendinae and papillary muscles in a pig's heart?

Yes, chordae tendinae and papillary muscles are present in a pig's heart. Chordae tendinae are fibrous cords that connect the papillary muscles to the valves of the heart, providing support and preventing backflow of blood. Papillary muscles contract to tighten the chordae tendinae during ventricular contraction, aiding in the proper function of the heart valves.
