In case of severe burn injuries, a person experiences a sudden increase in the number of dangerous bacteria in the gastrointestinal tract approximately 32%. The increase in the dangerous bacteria increase the chance of developing gastrointestinal conditions like irritable bowel disease, and other non-related conditions like rheumatoid arthritis and diabetes.
But in case of less severe burn injuries, the dangerous bacteria accounted for just 0.5% of the bacteria. An imbalance in the bacteria cause long term health consequences, in fact some of the complications could possibly even result in death of a person with severe burn injuries.
Alveolar walls are thin to enable the quick passage of oxygen in and out of the lungs. The lungs works hand-in-hand with the heart and also is responsible in converting blood that's de-oxygenated into an oxygenated blood that is usable by the organ systems of the body. The alveolar walls are also designed to have thin membranes so that it can expand and constrict quickly allowing us to breather properly.
