How lung capacity increases when doing consistent cardio and what happens anatomically?

Answer 1

My understanding is that at the very ends of your lungs are microscopic train stations where fresh oxygen gets into your blood and CO2 gets off. Cardio is like the maintenance team that keeps the train station running efficiently. Through exercise, this concentrated flushing of the system keeps it clean, shiny, working as intended. Without the flushing of the system gunk builds up and the train station stops working at its optimum.
