Doctors removed her lung due to the bacterial infection which had grown resistant to antibiotics shutting her organs, reports the Guardian.
A small artificial lung was connected to her heart and a successful lung transplant was done six days later after they got a donor.
Mammals, reptiles and birds use their musculoskeletal systems to support and foster breathing. In early tetrapods, air was driven into the lungs by the pharyngeal muscles via buccal pumping, a mechanism still seen in amphibians. In humans, the primary muscle that drives breathing is the diaphragm. The lungs also provide airflow that makes vocal sounds including human speech possible.
