TOPICS
GOALS
1. To understand the spacial relationships of structures that enter and exit the hilum of the lung
2. To relate structures of the hilum of the sternal angle of Louis and other bony landmarks
3. To relate structures of the hilum to the chambers of the heart and the aorta
4. To trace flow of blood in the pulmonary circulation
5. To relate the lungs to the clavicle and diaphragm

SUMMARY
1. The pulmonary arteries and mainstem bronchi are located superiorly in the hilum; the pulmonary veins are inferior, to enter the left atrium of the heart
2. The pulmonary arteries and mainstem bronchi are in the plane of the sternal angle of Louis inferior to the arch of the aorta (which in turn is inferior to the clavicular heads).
The pulmonary veins and left atrium are closer to the 3rd costocartilage eand intercostal space.
3. The pulmonary veins enter the posterior-most chamber of the heart (left atrium); the right pulmonary artery travels just inferior to the arch of the aorta (and anterior to the right mainstem bronchus)
4. The path of the catheter marked the flow of blood through the right side of the heart to the pulmonary trunk. Deoxygenated blood traveled via the pulmonary arteries to the lungs; oxygenated blood returned via the veins to the left atrium, then to the left ventricle and aorta
5. The lungs extend superior to the clavicle and inferior to the dome of the diaphragm
