Doctor insights on: Breathing Simulate Chronic Lung Disease Caused Smoking

Share

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

How would breathing through a straw simulate chronic lung disease caused by smoking?

Transplant center: The transplant center will list you for the allocation of the new donor lungs. The time that a patient remains on the list prior to finding a donor that is a good match varies and depends on a number of factors. Your age is only one of the factors. It also depends how many other kids your age are waiting. Once a good match is determined, the center moves quickly to perform the transplantation. ...Read more
