The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Chordae Tendineae**: Chordae tendineae are cord-like structures found in the heart. They are made of connective tissue and resemble strings or cords. 2. **Location of Chordae Tendineae**: These structures are primarily associated with the heart's ventricles. They connect the papillary muscles to the atrioventricular valves (which include the bicuspid/mitral valve and the tricuspid valve). 3. **Function of Chordae Tendineae**: The main function of the chordae tendineae is to prevent the eversion (or flipping) of the atrioventricular valves into the atria during ventricular contraction. This helps to prevent backflow of blood from the ventricles into the atria. 4. **Identifying the Correct Answer**: Given the options: - 1st: Ventricle - 2nd: Left auricle - 3rd: Right auricle - 4th: None of these Since chordae tendineae are found in the ventricles, the correct answer is the first option: **Ventricle**. **Final Answer**: Chordae tendineae in the heart are found in the **ventricle**. ---
