Question

what if somehow we replace lungs of humans by gills then what will happen​

Answer 1

Explanation:

A lung transplant is surgery done to remove a diseased lung and replace it with a healthy lung from another person. The surgery may be done for one lung or for both. Lung transplants can be done on people of almost all ages from newborns to adults up to age 65 and sometimes even later.

Types of lung transplant procedures include:

Single lung. This is the transplant of one lung.

Double lung. This is the transplant of both lungs.

Bilateral sequential. This is the transplant of both lungs, done one at a time. It’s also called bilateral single.

Heart-lung transplant. This is the transplant of both lungs and the heart taken from a single donor.

Most lungs that are transplanted come from deceased organ donors. This type of transplant is called a cadaveric transplant. Healthy, nonsmoking adults who are a good match may be able to donate part of one of their lungs. The part of the lung is called a lobe. This type of transplant is called a living transplant. People who donate a lung lobe can live healthy lives with the remaining lungs.

Answer 2

A lung transplant is a surgical procedure to replace a diseased or failing lung with a healthy lung, usually from a deceased donor. A lung transplant is reserved for people who have tried other medications or treatments, but their conditions haven't sufficiently improved.
