Answer 26

Right pulmonary artery

Left pulmonary artery

Question 27

Pulmonary Trunk divides at

Answer 27

at lower border of T4)

Question 28

Right pulmonary artery runs

Answer 28

behind ascending aorta & SVC to enter root of right lung

Question 29

Left pulmonary artery runs

Answer 29

in front of descending aorta to enter root of left lung.

Question 30

Ligamentum arteriosum

Answer 30

It is important in embryonic circulation, when it is a patent vessel (the ductus arteriosus).
It connects the pulmonary trunk with the arch of the aorta and allows blood to bypass the
lungs during development.
The vessel closes soon after birth and forms the ligamentous connection observed in the
adult.
