The bronchi branch out into each lung where oxygen is picked up by passing blood. The blood then carries the oxygen throughout the body. • For a variety of reasons, what happens during an asthma episode is that the bronchial tubes become narrow, or even blocked. As a result, air can't get in or out of the lungs easily, and the child begins to breathe heavily, wheeze or cough.There are two reasons the bronchi narrow: Either because they are squeezed by muscles from the outside or because they are blocked by mucus and swelling inside the bronchial tubes.
