Regarding structure of human heart chordae tendinae are present in:
Correct answer: D. Ventricle
- A. Atria
- B. Hepatic portal veins
- C. Coronary artery
- D. Ventricle
Explanation
Chordae tendineae are present in the ventricles of the heart.Chordae tendineae are fibrous cords that attach the flaps of the heart valves to the papillary muscles. The papillary muscles are located in the ventricles of the heart The chordae tendineae help to keep the flaps of the heart valves closed during ventricular contraction. When the ventricles contract, they push against the chordae tendineae. This pulls on the flaps of the heart valves, keeping them closed. This prevents blood from flowing back into the atria from the ventricles.
