the right and left pulmonary arteries arise from the pulmonary trunk at what level?
sternal angle
do pulmonary arteries follow the same course as the bronchi in the lung? what about veins?
yes, but veins run independently
where does the deoxygenated blood from the bronchial venous system drain?
into the pulmonary veins (yes, those with oxygenated blood returning to the heart)
describe how the bronchial arteries arise?
the two on the left arise directly from thoracic aorta
the one on the right is variable (aorta, posterior intercostal artery, left superior bronchial artery)
either way, the arteries are posterior to the branching of the trachea
what does it cause
how is it transmitted
*respiratory secretions

lymphatic drainage of the lungs
starting from the superficial subpleural and deep lymphatic plexuses, all lymph leaves along the root of the lung and drains to the inferior or superior tracheobronchial lymph nodes...the inferior lobe of BOTH lungs drains to the centrally placed inferior tracheobronchial nodes (mostly right side) as the left superior lobe follows a left sided course

from here, onwards to paratracheal nodes and bronchomediatstilnal trunks that empty into the subclavian trunks
what vessel is the internal thoracic artery a branch of?
R: phrenic nerve and root of the lung
nerve is anterior
