LUNG AND CHEST WALL GRAPH | COMPLIANCE explained | USMLE STEP 1 | RESPIRATORY PHYSIOLOGY

* We can compare balloon with aorta, wooden mug with stiff aorta in elder people or fibrosis in lung and shopping bag with veins or alveoli in emphysema.
* Chest wall try to move outward (expand) and lungs try to move inward(collapse).
* You can also compare inspiration in hysteresis graph with filling air in balloon.

* If you are first or second year medical student or if you have more than one year to prepare for USMLE Step 1 or any other exam then I strongly recommend you to watch Dr. Najeeb lectures to make your concepts very clear. If you don't have enough time to prepare for USMLE Step 1 then I would not recommend you to go through all the videos of Dr. Najeeb, just watch Neurology and Immunology.
