(En español: Broncoconstricción) Doesn't this sound like a cross
between a dinosaur and a snake? Actually, bronchoconstriction
affects the airways in a person's lungs. You can think of
airways like straws or tubes. They let air flow in and out so
you can breathe. These airways have muscles, but not the kind
you flex! When bronchoconstriction occurs, the muscles
surrounding the airways contract, or tighten. This narrows the
airways so there's less space inside for air to get through.
Bronchoconstriction happens to people who have asthma, but
asthma medicines can help relax the muscles in the airways and
make breathing easier.
