Lung

NOTE: Early in 2023, a new lung allocation based on continuous distribution will be implemented. The first of the FAQ documents below addresses the current lung allocation policy, which features a lung allocation score (LAS). The second FAQ document addresses the policy to be implemented in 2023 based on continuous distribution.

Questions and answers for transplant candidates about:

The lungs

Also called the windpipe, the trachea is the tube that connects your mouth and nose to your lungs. The primary bronchus transports air to and from the lungs. The right lung is larger than the left and contains the upper, middle and lower lobes. The left lung contains two lobes, the upper and lower lobe. The alveoli are tiny air sacs located in the lungs.

Functions of the lung

Lungs are a pair of highly elastic and spongy organs in the chest. They are the main organs involved in breathing. They take in air from the atmosphere and provide a place for oxygen to enter the blood and for carbon dioxide to leave the blood. The lungs are divided into lobes, with three on the right and two on the left.

Lung transplant procedures

Lung transplants may involve two lungs, a single lung or a lobe of a lung. Most of the lung lobe transplants have been performed for patients with cystic fibrosis and have involved the donation of a lung lobe from each of two living donors.
