Question

Pulmonary trunk and aorta are attached by

• A. Chordae tendinae
• B. Ligamentum arteriosus
• C. Coronary sulcus
• D. Pericardium.

Answer 1

The correct option is B Ligamentum arteriosus

B. Ligamentum arteiosus

Solution: Chordace tendinae is a connective tissue that connects the papillary musscles to the tricuspid valve and mitral valve.

Ligamentum arteriosus attaches pulmonary trunk and aorta.

Coronary sulcus separates atria from ventricles.

Pericardium is the fibrous sac that encloses the heart.

So the correct answer is "Ligamentum arteiosus".
