Question

In a foetus, ductus arteriosus connects

• A. Aorta and pulmonary artery
• B. Aorta and pulmonary vein
• C. Hepatic and pancreatic duct
• D. Pulmonary artery and vein

Answer 1

The correct option is A Aorta and pulmonary artery

The ductus arteriosus connects the pulmonary artery to the proximal descending aorta in the developing foetus. It allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs.

So, the correct answer is option A.
