About The Transplant

Lung Transplant
Lungs are amongst the most vital organs in the living body and are a must for survival. Normal humans have two healthy lungs though a single healthy lung is also enough for survival. Lungs are the main organ responsible for respiration and all other related biological process. These are present in the thoracic cavity of the chest. The main function of lungs is to transfer the inhaled oxygen to the bloodstream and to absorb the carbon dioxide from the bloodstream and finally exhale it out from the body. Lungs are vital since they are carriers of oxygen into the blood and oxygen is a must for all biological processes and hence for human survival.

Lung Transplant is the surgical process of replacing deceased lungs of an individual partially or wholly with donor’s lung’s lobe. Sometimes an individual needs only one lung to be transplanted for his or her survival but some other times both the lungs must be transplanted to ensure patient’s survival. Usually, the individuals suffering from one or the other kind of end-stage pulmonary diseases qualify for a lung transplant.
