It is TRUE that each lung is fed oxygen by a separate bronchus.
Humans respire through the use of lungs. Each human being possess two lungs and each lung has its own bronchi. The bronchi serve as the path for the movement of air from the nose / mouth to the alveoli in the lungs. The alveoli are surrounded by blood vessels and the oxygen from the outside enter the blood through the thin capillary wall of the blood vessels while the carbon dioxide is released to the outside through the same medium.
I would help but this is the type of project to do on your own. I'd suggest planning out the image then building from there, or use graphs on the internet for inspiration. I wish you luck though :>
